Studies have shown Pre-eclampsia as a risk indicator for Postpartum hemorrhage and D-dimer tends to rise in women with pre-eclampsia. Few studies that have shown the association between D-dimer and PPH have been controversial and differ according to ethnicity and lifestyle. Hence there is no suitable reference interval for D-dimer in predicting Postpartum hemorrhage among women with pre-eclampsia. Broad Objective: This study aimed to assess the association, sensitivity, and specificity of D-dimer as a laboratory predictor of postpartum hemorrhage among women with pre-eclampsia at KCMC hospital. Methodology: This was a hospital-based analytical cross-sectional study conducted at KCMC Hospital in Northern Tanzania from September 2022 to March 2023. A total of 195 women with pre-eclampsia were included in this study. Plasma D-dimer levels were taken from women with pre-eclampsia pre-delivery. Haematocrit was compared before and after delivery, and a fall of 10% was considered as Postpartum hemorrhage together with clinical assessment of the patient. Participants were divided among those who had severe features and those who did not have severe features and were further categorized into those who had PPH and those who did not have PPH. Logistic regression was used to determine the association between D-dimer and PPH adjusting for other factors. The Receiver Operating Curve (ROC) was used to evaluate the predictive value. Results: Higher median D-dimer levels were seen among women who had PPH compared to those who had no PPH. D-dimer was seen to be associated with PPH, thus for every unit increase of µg/ml of D-dimer among women who had pre-eclampsia without severe features there was a 14% significant increase in the odds of having postpartum hemorrhage and a 45% significant increase of having postpartum hemorrhage among those who had pre-eclampsia with severe features. Furthermore, the cut-off point of a D-dimer level of 0.66 µg/ml significantly predicts postpartum hemorrhage with a sensitivity of 75% and specificity of 55%. For those who had no severe features the cut-off point was 0.53 µg/ml with a sensitivity of 95% and specificity of 53%, and for those who had severe features the cut-off point was 3.58 µg/ml with a sensitivity of 50% and specificity of 96%. Conclusion: D-dimer can be used to predict postpartum hemorrhage among pre-eclampsia, especially among those who have severe features. This shows that D-dimer has specificity in predicting PPH in women with pre-eclampsia and can be applied in clinical services to save women from maternal morbidity and mortality. Blood products such as fresh frozen plasma, platelets, and whole blood together with tranexamic acid should be readily available in women with pre-eclampsia especially those with severe features with a D-dimer level of 3.58 µg/ml and above during delivery as they are at high risk of developing PPH.展开更多

Most maternal deaths from hemorrhage are preventable with support measures for clinical practice, such as: guiding protocols, training of professionals, organization and management of health services and provision of adequate conditions for the parturition process. Objective: To validate Rangel’s instrument with its application in the Maternity Ward of the General Hospital of Huambo, Angola. Methodology: This is a descriptive study with a quantitative approach. This is the sixth stage, called pre-test, of the Translation and Cultural Adaptation process. This instrument was sent for evaluation by the validators using the electronic data collection form named Google forms, with a seven-point Likert-type scale (from 7—totally agree to 1—totally disagree). The analysis was performed with the Cronbach’s Alpha coefficient index (>0.91) and the Content Validity Index (CVI > 0.98). Results: Of the 10 items of evaluation criteria of the instrument analyzed by the 20 validators, 100% of them obtained a Cronbach’s Alpha index rating of 0.91: clarity;coherence;scientific writing;relevance;sequence;uniqueness and updating. Coverage, item criticality and objectivity reached a Cronbach’s Alpha of 0.95. The Content Validity Index was 0.95 for coverage, coherence, item criticality, scientific writing, relevance and updating. Conclusion: Rangel’s instrument for nursing care aimed at preventing and controlling hemorrhage in the third period of birth, translated into Angolan Portuguese and validated by nurses, through the statistical results obtained in the validation, was considered reliable and necessary for clinical nursing practice in Huambo, Angola. .展开更多

Deaths are mostly preventable, and are related to socioeconomic development, organization of health services and professional training. Objective: To systematize alerts for the prevention of postpartum hemorrhage. Method: This is a technical essay developed from reflections on previously produced and published texts about maternal mortality and has hemorrhage as the focus of this study. Results: It presents the concept, classification of hemorrhage, risk factors and their classification, prevention strategies, universal recommendations, pharmacological and non-pharmacological interventions when hemorrhage already exists, bleeding assessment techniques;clinical evaluation, by laboratory examination and by shock index. Conclusions: Hemorrhage is a preventable cause of maternal death through the accomplishment of multiple care. Hospital care must be conducted by qualified professionals and in adequate numbers. The risk diagnosis must be carried out during prenatal care with the recording of clinical data accessible in the health care network. All references studied are not specific to nursing, as hemorrhage prevention requires multidisciplinary action.展开更多

Over half of these deaths occur in Sub-Saharan Africa with mortality rates of 500 - 1000 per 100,000 births, compared to approximately 5 - 10 in developed countries. Over decades in Sub Saharan Africa preventive measures and treatment protocols have been made to reduce maternal mortality caused by PPH. While rates of postpartum hemorrhage have continued to rise, there is a need to evaluate if its etiology and patterns have changed over time. Broad Objective: This study aims at describing trends in incidence, causes and maternal outcomes of Postpartum Hemorrhage at Muhimbili National Hospital for a period of 7 years. Methodology: This is a retrospective descriptive hospital-based study that has included all cases of postpartum hemorrhage at Muhimbili National Hospital, a tertiary hospital in Tanzania from 2014 to 2020. The data was analyzed using SPSS Version 26 and presented using frequency tables, figures and percentages. The trends of postpartum hemorrhage over time were determined using chi-square test and P-value where less than 0.05 was considered statistically significant. Results: Overall, the incidence of postpartum hemorrhage has been fluctuating over the years with minimum of 1.78% and maximum of 2.87% with no statistical significance. Out of 1113 enrolled cases of PPH, 422 (37.9%) were attributed to genital tears followed by uterine atony 285 (25.6%). A statistically significant increase in linear trend was observed in the postpartum hemorrhage cases due to uterine atony, uterine rupture and sub analysis on genital tears (cervical tear). Overall, there was a statistically significant change in trend of maternal outcomes throughout the years, with a P-value < 0.001 and likelihood of complications increasing over time. Conclusion: The trend in the incidence of postpartum hemorrhage has been fluctuating over the years during the study period. The leading cause of postpartum hemorrhage was genital tears, followed by uterine atony with a significant increase in adverse maternal outcomes over the years. Continuous health education to medical personnel to improve timely and proper diagnosis of women in danger of PPH and timely referral, thus improve maternal morbidity and mortality.展开更多

Our aim is to detect the risks of multilevel PPH in different cesarean section (CS) groups [including nulliparous CS with indications, nulliparous CS without indications, repeat cesarean (RC), vaginal birth after cesarean (VBAC), cesarean after vaginal birth (CAVB)]. We conducted a retrospective cohort study, and the data on 127 145 women collected from January 2014 to May 2016 and from 35 tertiary hospitals in Shanxi province, China, were reviewed. Based on the measuring results of PPH, an ordered logistic regression model was used to analyze the adjusted PPH risks for each of the CS groups, and comparisons were drawn between them. Finally, a total of 99 066 nulliparous (77.92%) and 28 079 multiparous (22.08%) women were observed. The number of CS cases was 61 117, and the rate for CS was 48.07%. A total of 10 029 women did not show indications for CS and accounted for 16.41% of the CS parturient, whereas 9103 women underwent a repeated cesarean, with a CS frequency of 14.89%. The number of VBAC cases was 989, whose rate was 9.88% in prior CS women. The number (proportions) of PPH was 3658 (2.88%) in L1 (PPH volume: ≥900 and 〈1500 mL), 520 (0.41%) in L2 (PPH volume: ≥1500 and〈2100 mL), and 201 (0.16%) in L3 (PPH volume: ≥2100 mL). The Ln (n= 1, 2, 3, etc.) represented the increasing order of PPH severity. In the adjusted results, compared with spontaneous vaginal delivery (SVD) as the reference group, in the adjusted result for nulliparous, there was a decreased PPH risk in CS with indications (OR: 2.32; CI: 2.04-2.62), which was lower than that of CS without indications (OR: 2.50; CI: 2.01-2.96). The highest PPH risk in all subgroups (i.e. nulliparous and multiparous groups) was observed in the RC (OR: 3.61; CI: 3.16-4.17), which was nearly twice higher than that of the VBAC (OR: 1.82; CI: 1.33-2.52). CAVB (OR: 1.03; CI: 0.65-1.62) showed no significant difference with the reference group. Thus, we deemed that CS should be avoided in nulliparous pregnancies unless indicated, to prevent or reduce the rates for the use of RC or VBAC which are high risks of severe PPH to the parturient women.展开更多

Methods We retrospectively reviewed the medical records of patients with placenta accreta between January 2010 and August 2014. Totally 18 women(mean age 30.8±4.2 years) of primary massive postpartum hemorrhage with diagnosis of placenta accrete received treatment of UAE after delivery. Images of DSA and medical records were reviewed. Technical success was defined as control of bleeding after embolization. The complications, control of hemorrhage and recurrent bleeding of the placenta left inside the uterus were retrospectively collected for assessment. Results All patients underwent transcatheter embolization of bilateral uterine arteries. The technical success rate of embolization was 100%. Bleeding was controlled in 17 of 18 patients(94%) during follow-up period(median 18 months, 3-31months) without further bleeding recurred. One patient with placenta percreta undertook an emergent hysterectomy along with surgical bladder repair after UAE because of persistent uterine bleeding. Eight patients had postembolization syndrome and no other complications occurred. Conclusion Uterine artery embolization is an effective and safe treatment for the management of primary postpartum massive hemorrhage associated with placenta accreta.展开更多

Methods: Retrospective review of 58 women who underwent balloon tamponade for severe PPH, during a period of 5 years and 10 months, at Russells Hall Hospital, a busy district general hospital in UK. Clinical success was defined as control of bleeding without need for further intervention. Results: Fifty-eight women (mean age, 30 years;range, 18 - 42) underwent balloon tamponade, of which twenty seven (46.5%) women delivered vaginally and 31 (53.5%) women were delivered by cesarean section. Uterine atony was the main cause of PPH (31 cases). Balloon tamponade was used prophylactically in 11 high risk women in anticipation of potential PPH. Rusch balloon was used in 48 cases and Bakri balloon in 10 cases. Clinical success rate of balloon tamponade was 87.2%. Three patients in this study required hysterectomy. Conclusion: Balloon tamponade is an effective means of controlling severe PPH with success rates of around 87%. There should also be a low threshold for prophylactic use of balloon tamponade in women at high risk of PPH, considering its ease of use, low complication rate and ability to maintain reproductive ability.展开更多

It has been commonly used in gynecology and obstetrics, especially for the management of postpartum hemorrhage (PPH). For this purpose, 1000 μg intrarectal (insertion of five 200 μg tablets) has been recommended as the third line after injectable oxytocin and methylergometrine. We proposed to manufacture a 1000 μg misoprostol suppository by determining formulation, release and stability. The administration facility was also evaluated. Several formulations of misoprostol suppositories were set up and evaluated. Misoprostol tablets and lipophilic bases (Hard fat—Adeps solidus Ph. Eur., Witepsol? H15 and Suppocire? AM and AS2X) were used to obtain suppositories. Surfactants were also tested (polysorbates Tween? 20, Tween? 80 and sodium lauryl sulfate (SLS)). The formula was monitored by the misoprostol release curve with an in vitro test and dosed by a HPLC method. Stability was determined by evaluating the percentage of misoprostol content remaining over the time in suppositories stored at 4℃ and 25℃. Facility of use versus tablets was evaluated by obstetricians of a Swiss regional hospital using a questionnaire. Misoprostol release was facilitated by adding surfactant to the lipophilic base. After 30 minutes, 59% ± 1.4% and 57% ± 8.2% of misoprostol was released with Adeps solidus + 1% SLS and Adeps solidus + 5% Tween 20 respectively. SLS was discarded to the final formula because of its irritating effect. After 7 months, suppositories still contained 94% ± 3.7% misoprostol with storage at 4℃. The administration was considered easier and faster compared with intra rectal use of tablets. The formula, consisting of 5 crushed misoprostol tablets dispersed in a suppository base made of Adeps solidus + 5% Tween? 20, is stable for at least 7 months at 4?C and facilitates the rectal administration of misoprostol in the treatment of PPH.展开更多

Study Design: We conducted a survey of OB/GYNs (n = 220) and HEMs (n = 30) to describe the characteristics of current treatment strategies for postpartum hemorrhage. Surveys were administered via a structured questionnaire on a secure internet website from 5 - 12 October 2009. Results: The majority of OB/GYN and HEM respondents were practicing in a community hospital environment (77%). Of the OB/GYNs, the majority practiced at hospitals with over 2000 deliveries per year (77%). A majority (58%) of OB/GYNs were affiliated with hospitals that lacked a massive transfusion protocol to treat severe postpartum hemorrhage. Subsequent to uterine massage and additional oxytocin, the majority of OB/GYNs (73%), preferred the administration of Methergine? as the next level of intervention for postpartum hemorrhage. There was considerable variability in response to specific treatment strategies for several hypothetical case scenarios;however, the large majority of OB/GYNs favored obstetrical procedures over interventional radiology or administration of rFVIIa. A large majority (77%) of physicians who are familiar with rRVIIa as treatment for postpartum hemorrhage reported being very satisfied with the agent for this indication. Conclusions: An established, systematic treatment strategy among OB/GYNs emerged only in the case of mild postpartum hemorrhage.展开更多

We hypothesize that magnesium sulfate (MgSO4) could be a contributing factor. MgSO4 might increase the incidence of PPH by induction of vasodilation, tocolytic effects, and effects on the blood like red cell deformity, platelet activity inhibition and a prolonged bleeding time. Based on these effects of MgSO4 a correlation with PPH is suspected. MgSO4 is widely used in the prevention of eclampsia. However, the working mechanism of this effective drug is largely unknown. We performed a systematic search to find all Randomized Controlled trials (RCTs) containing MgSO4 in preeclamsia as well as all MgSO4 studies with information on PPH. Titles, abstracts and references of publications were evaluated for appropriateness and whether they met the inclusion criteria. RCTs about MgSO4 with original data on PPH prevalence were included in our systematic review. We calculated the relative risk of PPH in every study as well as an overall relative risk. Four relevant and valid RCTs were found, totalling 11,621 relevant patients. The relative risk of PPH in women treated with MgSO4 is 0.964 (95% CI 0.886 - 1.050) In this systematic review we found no significant increase in PPH in women treated with MgSO4. However, there is still room for discussion due to the heterogeneity in methods (dosage and duration of treatment), results, and tertiary outcomes, as well as the small number of studies found with respect to this important issue.展开更多

Materials and Methods: The subjects were 40 women (mean age, 33 years;age range, 21 - 42 years) who underwent UAE for PPH at two institutes from June 2001 to May 2011. The rates of clinical success (avoidance of hysterectomy) and complications were calculated. Differences in related factors between primary PPH and secondary PPH and between caesarean section and vaginal delivery were examined. The risk factors associated with hysterectomy were also examined. Results: The overall clinical success rate was 90% (93% of primary PPH, 77% of secondary PPH, and 87.5% of PPH with cesarean section), and the overall complication rate was 10%. There were significant differences in time to PPH (P < 0.0001) and in blood infusion after UAE (P = 0.0158) between subtypes of primary and secondary PPH and in blood infusion before UAE (P = 0.0052) between delivery methods. The significant factors associated with hysterectomy were cesarean section (P = 0.02), severe PPH (>1000 mL bleeding, P = 0.03), and embolization of non-uterine arteries (P = 0.02).展开更多

Material and Methods: A retrospective analysis was carried out on all 24 cases of postpartum hemorrhage due to uterine atony with an estimated blood loss of more than 800 mL, in which standardized guidelines were obtained. We included all women who gave birth at the General Hospital of Vienna, the Medical University Vienna, during the period from January 1st 2003 and December 31st 2009 and who suffered blood loss 800 mL at minimum due to uterine atony. Results: The guidelines were in use for 14% - 71%. The average blood loss of the 24 cases with uterine atony was 1342 mL. Conclusion: The management process of postpartum hemorrhage due to uterine atony deviates from the hospital’s guidelines in many cases.展开更多

Previous reports have shown that misoprostol is effective in reducing blood loss during and after CS. However, the optimum time for its administration to decrease the amount of PPH is still under discussion. Objective: To compare the effect of preoperative and postoperative administration of sublingual misoprostol (400 μg) in reducing the amount of blood loss during and 24 hours after CS. Setting: Obstetrics and Gynecology Department, Faculty of Medicine, Assiut University, Assiut, Egypt, between January 2017 and July 2018. Study Design: A prospective, randomized clinical trial. Methods: Four-hundred thirty women fulfilling the inclusions criteria: elective lower segment CS at term (≥37 weeks) with normal fetal heart tracing who accepted to participate in the study. Patients were divided into two groups;Patients assigned to group 1 received 400 μg sublingual misoprostol immediately after urinary catheterization and before skin incision, while patients assigned to group 2 received sublingual misoprostol immediately after skin closure. The primary outcome was the estimation of intraoperative and postoperative blood loss for 24 hours. Results: There was a significant reduction in the intraoperative blood loss in group 1 compared with group 2 (403.51 ± 72.99 vs. 460.99 ± 74.66 ml, respectively). Also, there was a significant reduction in postoperative blood loss in group 1 compared with group 2 with a statistical significance (169.45 ± 12.03 vs. 195.77 ± 13.34 ml, respectively). Postoperative hemoglobin and Hematocrit values were significantly higher in group 1 compared with group 2. Conclusions: Preoperative administration of sublingual misoprostol (400 μg) during CS is better than postoperative administration as it is associated with a reduction in the amount of intraoperative and postoperative blood loss and drop in hemoglobin level.展开更多

According to the medication, each group was divided into the carbetocin group and oxytocin group with 64 cases in each group. After fetus delivery, the puerpera in the carbetocin group were given intravenous injection of carbetocin (100μg), while the puerpera in the oxytocin group were given intravenous injection of oxytocin (10 U)+0.9% NaCl (500 mL) for 2 h. The amount of bleeding at delivery, 2 h and 24 h after delivery in each group was observed. A volume of 5 mL elbow venous blood before delivery and 24 h after delivery was extracted. The automatic blood cell analyzer was used to detect the decreased value of 24 h hemoglobin in each group. The coagulation detector was used to detect PT, APTT, and FIB before delivery and 24 h after delivery. The blood pressure and heart rate before and after medication in each group were observed.Results: The amount of bleeding at delivery, 2 h and 24 h after delivery in the carbetocin group was signiifcantly less than that in the oxytocin group (P<0.05). The decreased value of 24 h hemoglobin after delivery in the carbetocin group was signiifcantly less than that in the oxytocin group (P<0.05). The indicators of coagulation function 24 h after delivery in each group were not signiifcantly changed (P>0.05). The heart rate and blood pressure after medication in each group were not significantly changed when compared with before medication (P>0.05).Conclusions:Carbetocin can effectively prevent the postpartum hemorrhage caused by uterine inertia, and is safe and effective in application of vaginal delivery and cesarean section;therefore, it deserves to be widely recommended in the clinic.展开更多

Strengthening the Reporting of Observational Studies in Epidemiology(STROBE) strategy was chosen as the tool for quality assessment of included studies, and data concerning the basic study characteristics and assessment indicators were extracted.Results: Eleven studies were included in this review. The assessment indicators in different reports covered heart rate, blood pressure, placental and birth canal check, hemoglobin(Hb), hematocrit(HCT),coagulation function tests, hemodynamic parameters and arterial blood gas, but no data on the assessment of postpartum uterine contraction were found. The relationship between indicators and blood loss varies.The overall quality of 9 manuscripts was comparatively high or moderate, and 2 were rated as low.Conclusions: The association between blood loss and clinical symptoms is not conclusive based on the present studies, and specific cut-off points could not be formulated to determine the approximate amount of blood loss. However, some cut-off points can be considered warning signs for the need of advanced interventions, such as heart rate, prothrombin time, and placental implantation. Further research on comprehensive assessment and cut-off points should be performed such that birth attendants can distinguish PPH as early as possible.展开更多

Methods:70 patients with postpartum hemorrhage after placenta previa cesarean section who were treated in Chengdu Women & Children's Central Hospital between January 2014 and February 2017 were collected and then divided into the control group (n=35) who received uterine packing therapy and the observation group (n=35) who received Hemabate combined with packing therapy according to random number table. Serum levels of oxidative stress indexes and stress hormones immediately after operation and 24 h after operation were compared between two groups of patients.Results: Immediately after operation and 24 h after operation, serum oxidative stress indexes ROS and MDA levels of observation group were significantly lower than those of control group while SOD, GSH-px and CAT levels were significantly higher than those of control group, and serum stress hormones NE, E and Cor levels were significantly lower than those of control group.Conclusion: Hemabate combined with packing therapy can effectively reduce systemic stress response in patients with postpartum hemorrhage after placenta previa cesarean section, is a more ideal way of the bleeding.展开更多
文摘Objective:To evaluate the effect of bilateral hypogastric artery ligation(BHGAL)on women's pregnancy outcomes and fertility rates in cases with severe postpartum hemorrhage.Methods:Patients hospitalized in a tertiary care center between 2007 and 2018 were included in the study.The records of cases were obtained from the hospital database,retrospectively.Maternal demographic data,morbidities or complications associated with BHGAL surgery,any additional haemostatic interventional or surgical procedures,preoperative admission and lowest postoperative haematocrit-hemoglobin values,blood products given,type of anaesthesia,intensive care unit(ICU)and length of hospital stay were recorded.In cases without surgical sterilization,future fertility and subsequent pregnancy outcomes were assessed for at least two years after operation.Information was obtained through face-to-face or telephone interviews with patients whose long-term fertility and subsequent pregnancy outcomes were assessed.Results:Sixty-eight patients with BHGAL surgery history were included in the study.26 Of 37 cases(70%)that did not undergo surgical sterilization had a desire for pregnancy after the surgery.Six of these cases(23%)were diagnosed with secondary infertility.The fertility rate of these cases was 77%,and subsequent pregnancy was detected in 20 women.A total of 25 pregnancies,including first and second pregnancies,developed,and 15 of these pregnancies resulted in term delivery,six preterm births,one stillbirth,and three abortions.Conclusions:The postoperative pregnancy rate was found to be higher than the rate of women with infertility problems,and this surgery does not seem to adversely affect pregnancy outcomes.This is a tertiary center experience and cohort studies with large patient series are needed.

文摘BACKGROUND Postpartum hemorrhage(PPH)is a leading cause of maternal mortality,and hysterectomy is an important intervention for managing intractable PPH.Accurately predicting the need for hysterectomy and taking proactive emergency measures is crucial for reducing mortality rates.AIM To develop a risk prediction model for PPH requiring hysterectomy in the ethnic minority regions of Qiandongnan,China,to help guide clinical decision-making.METHODS The study included 23490 patients,with 1050 having experienced PPH and 74 who underwent hysterectomies.The independent risk factors closely associated with the necessity for hysterectomy were analyzed to construct a risk prediction model,and its predictive efficacy was subsequently evaluated.RESULTS The proportion of hysterectomies among the included patients was 0.32%(74/23490),representing 7.05%(74/1050)of PPH cases.The number of deliveries,history of cesarean section,placenta previa,uterine atony,and placenta accreta were identified in this population as independent risk factors for requiring a hysterectomy.Receiver operating characteristic curve analysis of the prediction model showed an area under the curve of 0.953(95%confidence interval:0.928-0.978)with a sensitivity of 90.50%and a specificity of 90.70%.CONCLUSION The model demonstrates excellent predictive power and is effective in guiding clinical decisions regarding PPH in the ethnic minority regions of Qiandongnan,China.
文摘Background: Postpartum hemorrhage (PPH) is the major contributor to maternal mortality and morbidity worldwide as well as in Tanzania. Studies have shown Pre-eclampsia as a risk indicator for Postpartum hemorrhage and D-dimer tends to rise in women with pre-eclampsia. Few studies that have shown the association between D-dimer and PPH have been controversial and differ according to ethnicity and lifestyle. Hence there is no suitable reference interval for D-dimer in predicting Postpartum hemorrhage among women with pre-eclampsia. Broad Objective: This study aimed to assess the association, sensitivity, and specificity of D-dimer as a laboratory predictor of postpartum hemorrhage among women with pre-eclampsia at KCMC hospital. Methodology: This was a hospital-based analytical cross-sectional study conducted at KCMC Hospital in Northern Tanzania from September 2022 to March 2023. A total of 195 women with pre-eclampsia were included in this study. Plasma D-dimer levels were taken from women with pre-eclampsia pre-delivery. Haematocrit was compared before and after delivery, and a fall of 10% was considered as Postpartum hemorrhage together with clinical assessment of the patient. Participants were divided among those who had severe features and those who did not have severe features and were further categorized into those who had PPH and those who did not have PPH. Logistic regression was used to determine the association between D-dimer and PPH adjusting for other factors. The Receiver Operating Curve (ROC) was used to evaluate the predictive value. Results: Higher median D-dimer levels were seen among women who had PPH compared to those who had no PPH. D-dimer was seen to be associated with PPH, thus for every unit increase of µg/ml of D-dimer among women who had pre-eclampsia without severe features there was a 14% significant increase in the odds of having postpartum hemorrhage and a 45% significant increase of having postpartum hemorrhage among those who had pre-eclampsia with severe features. Furthermore, the cut-off point of a D-dimer level of 0.66 µg/ml significantly predicts postpartum hemorrhage with a sensitivity of 75% and specificity of 55%. For those who had no severe features the cut-off point was 0.53 µg/ml with a sensitivity of 95% and specificity of 53%, and for those who had severe features the cut-off point was 3.58 µg/ml with a sensitivity of 50% and specificity of 96%. Conclusion: D-dimer can be used to predict postpartum hemorrhage among pre-eclampsia, especially among those who have severe features. This shows that D-dimer has specificity in predicting PPH in women with pre-eclampsia and can be applied in clinical services to save women from maternal morbidity and mortality. Blood products such as fresh frozen plasma, platelets, and whole blood together with tranexamic acid should be readily available in women with pre-eclampsia especially those with severe features with a D-dimer level of 3.58 µg/ml and above during delivery as they are at high risk of developing PPH.
文摘BACKGROUND Transcatheter arterial embolization(TAE)has been widely used as an effective and a safe treatment method and was often used as an alternative to the surgical management,but there are limited studies on the efficacy and the safety for patients undergoing their secondary postpartum hemorrhage(PPH).AIM To evaluate the usefulness of TAE for secondary PPH focusing on the angiographic findings.METHODS We conducted a research from January 2008 to July 2022 on all 83 patients(mean:32 years,range:24-43 years)presented with secondary PPH and they were treated with TAE in two university hospitals.The medical records and angiography were retrospective reviewed in order to evaluate the patients’characteristics,delivery details,clinical status and peri-embolization management,angiography and embolization details,technical/clinical success and complications.The group with active bleeding sign and the group without it were also compared and analyzed.RESULTS On angiography,46(55.4%)patients showed active bleeding signs such as contrast extravasation(n=37)or pseudoaneurysm(n=8)or both(n=1),and 37(44.6%)patients showed non-active bleeding signs such as only spastic uterine artery(n=2)or hyperemia(n=35).In the active bleeding sign group there were more multiparous patients,low platelet count,prothrombin time prolongation,and high transfusion requirements.The technical success rates were 97.8%(45/46)in active bleeding sign group and 91.9%(34/37)in non-active bleeding sign group,and the overall clinical success rates were 95.7%(44/46)and 97.3%(36/37).An uterine rupture with peritonitis and abscess formation occurred to one patient after the embolization,therefore hysterostomy and retained placenta removal were performed which was a major complication.CONCLUSION TAE is an effective and a safe treatment method for controlling secondary PPH regardless of angiographic findings.
文摘In the immediate postpartum period, women need to be observed by the obstetric nurse so that measures can be taken to prevent hemorrhages and reduce its complications. Most maternal deaths from hemorrhage are preventable with support measures for clinical practice, such as: guiding protocols, training of professionals, organization and management of health services and provision of adequate conditions for the parturition process. Objective: To validate Rangel’s instrument with its application in the Maternity Ward of the General Hospital of Huambo, Angola. Methodology: This is a descriptive study with a quantitative approach. This is the sixth stage, called pre-test, of the Translation and Cultural Adaptation process. This instrument was sent for evaluation by the validators using the electronic data collection form named Google forms, with a seven-point Likert-type scale (from 7—totally agree to 1—totally disagree). The analysis was performed with the Cronbach’s Alpha coefficient index (>0.91) and the Content Validity Index (CVI > 0.98). Results: Of the 10 items of evaluation criteria of the instrument analyzed by the 20 validators, 100% of them obtained a Cronbach’s Alpha index rating of 0.91: clarity;coherence;scientific writing;relevance;sequence;uniqueness and updating. Coverage, item criticality and objectivity reached a Cronbach’s Alpha of 0.95. The Content Validity Index was 0.95 for coverage, coherence, item criticality, scientific writing, relevance and updating. Conclusion: Rangel’s instrument for nursing care aimed at preventing and controlling hemorrhage in the third period of birth, translated into Angolan Portuguese and validated by nurses, through the statistical results obtained in the validation, was considered reliable and necessary for clinical nursing practice in Huambo, Angola. .
文摘Background: Postpartum hemorrhage is one of the main causes of maternal mortality, mainly in underdeveloped countries. Deaths are mostly preventable, and are related to socioeconomic development, organization of health services and professional training. Objective: To systematize alerts for the prevention of postpartum hemorrhage. Method: This is a technical essay developed from reflections on previously produced and published texts about maternal mortality and has hemorrhage as the focus of this study. Results: It presents the concept, classification of hemorrhage, risk factors and their classification, prevention strategies, universal recommendations, pharmacological and non-pharmacological interventions when hemorrhage already exists, bleeding assessment techniques;clinical evaluation, by laboratory examination and by shock index. Conclusions: Hemorrhage is a preventable cause of maternal death through the accomplishment of multiple care. Hospital care must be conducted by qualified professionals and in adequate numbers. The risk diagnosis must be carried out during prenatal care with the recording of clinical data accessible in the health care network. All references studied are not specific to nursing, as hemorrhage prevention requires multidisciplinary action.
文摘Worldwide obstetric hemorrhage remains the leading cause of maternal mortality, accounting for over one quarter of maternal deaths. Over half of these deaths occur in Sub-Saharan Africa with mortality rates of 500 - 1000 per 100,000 births, compared to approximately 5 - 10 in developed countries. Over decades in Sub Saharan Africa preventive measures and treatment protocols have been made to reduce maternal mortality caused by PPH. While rates of postpartum hemorrhage have continued to rise, there is a need to evaluate if its etiology and patterns have changed over time. Broad Objective: This study aims at describing trends in incidence, causes and maternal outcomes of Postpartum Hemorrhage at Muhimbili National Hospital for a period of 7 years. Methodology: This is a retrospective descriptive hospital-based study that has included all cases of postpartum hemorrhage at Muhimbili National Hospital, a tertiary hospital in Tanzania from 2014 to 2020. The data was analyzed using SPSS Version 26 and presented using frequency tables, figures and percentages. The trends of postpartum hemorrhage over time were determined using chi-square test and P-value where less than 0.05 was considered statistically significant. Results: Overall, the incidence of postpartum hemorrhage has been fluctuating over the years with minimum of 1.78% and maximum of 2.87% with no statistical significance. Out of 1113 enrolled cases of PPH, 422 (37.9%) were attributed to genital tears followed by uterine atony 285 (25.6%). A statistically significant increase in linear trend was observed in the postpartum hemorrhage cases due to uterine atony, uterine rupture and sub analysis on genital tears (cervical tear). Overall, there was a statistically significant change in trend of maternal outcomes throughout the years, with a P-value < 0.001 and likelihood of complications increasing over time. Conclusion: The trend in the incidence of postpartum hemorrhage has been fluctuating over the years during the study period. The leading cause of postpartum hemorrhage was genital tears, followed by uterine atony with a significant increase in adverse maternal outcomes over the years. Continuous health education to medical personnel to improve timely and proper diagnosis of women in danger of PPH and timely referral, thus improve maternal morbidity and mortality.

文摘Postpartum hemorrhage (PPH) is one of the most adverse obstetric outcomes. Our aim is to detect the risks of multilevel PPH in different cesarean section (CS) groups [including nulliparous CS with indications, nulliparous CS without indications, repeat cesarean (RC), vaginal birth after cesarean (VBAC), cesarean after vaginal birth (CAVB)]. We conducted a retrospective cohort study, and the data on 127 145 women collected from January 2014 to May 2016 and from 35 tertiary hospitals in Shanxi province, China, were reviewed. Based on the measuring results of PPH, an ordered logistic regression model was used to analyze the adjusted PPH risks for each of the CS groups, and comparisons were drawn between them. Finally, a total of 99 066 nulliparous (77.92%) and 28 079 multiparous (22.08%) women were observed. The number of CS cases was 61 117, and the rate for CS was 48.07%. A total of 10 029 women did not show indications for CS and accounted for 16.41% of the CS parturient, whereas 9103 women underwent a repeated cesarean, with a CS frequency of 14.89%. The number of VBAC cases was 989, whose rate was 9.88% in prior CS women. The number (proportions) of PPH was 3658 (2.88%) in L1 (PPH volume: ≥900 and 〈1500 mL), 520 (0.41%) in L2 (PPH volume: ≥1500 and〈2100 mL), and 201 (0.16%) in L3 (PPH volume: ≥2100 mL). The Ln (n= 1, 2, 3, etc.) represented the increasing order of PPH severity. In the adjusted results, compared with spontaneous vaginal delivery (SVD) as the reference group, in the adjusted result for nulliparous, there was a decreased PPH risk in CS with indications (OR: 2.32; CI: 2.04-2.62), which was lower than that of CS without indications (OR: 2.50; CI: 2.01-2.96). The highest PPH risk in all subgroups (i.e. nulliparous and multiparous groups) was observed in the RC (OR: 3.61; CI: 3.16-4.17), which was nearly twice higher than that of the VBAC (OR: 1.82; CI: 1.33-2.52). CAVB (OR: 1.03; CI: 0.65-1.62) showed no significant difference with the reference group. Thus, we deemed that CS should be avoided in nulliparous pregnancies unless indicated, to prevent or reduce the rates for the use of RC or VBAC which are high risks of severe PPH to the parturient women.
文摘Objective To evaluate the efficacy and safety of uterine artery embolization(UAE) in the management of primary postpartum hemorrhage associated with placenta accreta. Methods We retrospectively reviewed the medical records of patients with placenta accreta between January 2010 and August 2014. Totally 18 women(mean age 30.8±4.2 years) of primary massive postpartum hemorrhage with diagnosis of placenta accrete received treatment of UAE after delivery. Images of DSA and medical records were reviewed. Technical success was defined as control of bleeding after embolization. The complications, control of hemorrhage and recurrent bleeding of the placenta left inside the uterus were retrospectively collected for assessment. Results All patients underwent transcatheter embolization of bilateral uterine arteries. The technical success rate of embolization was 100%. Bleeding was controlled in 17 of 18 patients(94%) during follow-up period(median 18 months, 3-31months) without further bleeding recurred. One patient with placenta percreta undertook an emergent hysterectomy along with surgical bladder repair after UAE because of persistent uterine bleeding. Eight patients had postembolization syndrome and no other complications occurred. Conclusion Uterine artery embolization is an effective and safe treatment for the management of primary postpartum massive hemorrhage associated with placenta accreta.
文摘Objective: To evaluate the effectiveness of balloon tamponade in the management of postpartum hemorrhage (PPH). Methods: Retrospective review of 58 women who underwent balloon tamponade for severe PPH, during a period of 5 years and 10 months, at Russells Hall Hospital, a busy district general hospital in UK. Clinical success was defined as control of bleeding without need for further intervention. Results: Fifty-eight women (mean age, 30 years;range, 18 - 42) underwent balloon tamponade, of which twenty seven (46.5%) women delivered vaginally and 31 (53.5%) women were delivered by cesarean section. Uterine atony was the main cause of PPH (31 cases). Balloon tamponade was used prophylactically in 11 high risk women in anticipation of potential PPH. Rusch balloon was used in 48 cases and Bakri balloon in 10 cases. Clinical success rate of balloon tamponade was 87.2%. Three patients in this study required hysterectomy. Conclusion: Balloon tamponade is an effective means of controlling severe PPH with success rates of around 87%. There should also be a low threshold for prophylactic use of balloon tamponade in women at high risk of PPH, considering its ease of use, low complication rate and ability to maintain reproductive ability.

文摘Misoprostol is a prostaglandin E1 analogue used to prevent and treat gastric ulcers. It has been commonly used in gynecology and obstetrics, especially for the management of postpartum hemorrhage (PPH). For this purpose, 1000 μg intrarectal (insertion of five 200 μg tablets) has been recommended as the third line after injectable oxytocin and methylergometrine. We proposed to manufacture a 1000 μg misoprostol suppository by determining formulation, release and stability. The administration facility was also evaluated. Several formulations of misoprostol suppositories were set up and evaluated. Misoprostol tablets and lipophilic bases (Hard fat—Adeps solidus Ph. Eur., Witepsol? H15 and Suppocire? AM and AS2X) were used to obtain suppositories. Surfactants were also tested (polysorbates Tween? 20, Tween? 80 and sodium lauryl sulfate (SLS)). The formula was monitored by the misoprostol release curve with an in vitro test and dosed by a HPLC method. Stability was determined by evaluating the percentage of misoprostol content remaining over the time in suppositories stored at 4℃ and 25℃. Facility of use versus tablets was evaluated by obstetricians of a Swiss regional hospital using a questionnaire. Misoprostol release was facilitated by adding surfactant to the lipophilic base. After 30 minutes, 59% ± 1.4% and 57% ± 8.2% of misoprostol was released with Adeps solidus + 1% SLS and Adeps solidus + 5% Tween 20 respectively. SLS was discarded to the final formula because of its irritating effect. After 7 months, suppositories still contained 94% ± 3.7% misoprostol with storage at 4℃. The administration was considered easier and faster compared with intra rectal use of tablets. The formula, consisting of 5 crushed misoprostol tablets dispersed in a suppository base made of Adeps solidus + 5% Tween? 20, is stable for at least 7 months at 4?C and facilitates the rectal administration of misoprostol in the treatment of PPH.
文摘Objective: To identify current treatment strategies for postpartum hemorrhage used by obstetricians (OB/GYNs) and hematologists (HEMs). Study Design: We conducted a survey of OB/GYNs (n = 220) and HEMs (n = 30) to describe the characteristics of current treatment strategies for postpartum hemorrhage. Surveys were administered via a structured questionnaire on a secure internet website from 5 - 12 October 2009. Results: The majority of OB/GYN and HEM respondents were practicing in a community hospital environment (77%). Of the OB/GYNs, the majority practiced at hospitals with over 2000 deliveries per year (77%). A majority (58%) of OB/GYNs were affiliated with hospitals that lacked a massive transfusion protocol to treat severe postpartum hemorrhage. Subsequent to uterine massage and additional oxytocin, the majority of OB/GYNs (73%), preferred the administration of Methergine? as the next level of intervention for postpartum hemorrhage. There was considerable variability in response to specific treatment strategies for several hypothetical case scenarios;however, the large majority of OB/GYNs favored obstetrical procedures over interventional radiology or administration of rFVIIa. A large majority (77%) of physicians who are familiar with rRVIIa as treatment for postpartum hemorrhage reported being very satisfied with the agent for this indication. Conclusions: An established, systematic treatment strategy among OB/GYNs emerged only in the case of mild postpartum hemorrhage.
文摘The incidence of Postpartum Hemorrhage (PPH) is increasing in the western world. We hypothesize that magnesium sulfate (MgSO4) could be a contributing factor. MgSO4 might increase the incidence of PPH by induction of vasodilation, tocolytic effects, and effects on the blood like red cell deformity, platelet activity inhibition and a prolonged bleeding time. Based on these effects of MgSO4 a correlation with PPH is suspected. MgSO4 is widely used in the prevention of eclampsia. However, the working mechanism of this effective drug is largely unknown. We performed a systematic search to find all Randomized Controlled trials (RCTs) containing MgSO4 in preeclamsia as well as all MgSO4 studies with information on PPH. Titles, abstracts and references of publications were evaluated for appropriateness and whether they met the inclusion criteria. RCTs about MgSO4 with original data on PPH prevalence were included in our systematic review. We calculated the relative risk of PPH in every study as well as an overall relative risk. Four relevant and valid RCTs were found, totalling 11,621 relevant patients. The relative risk of PPH in women treated with MgSO4 is 0.964 (95% CI 0.886 - 1.050) In this systematic review we found no significant increase in PPH in women treated with MgSO4. However, there is still room for discussion due to the heterogeneity in methods (dosage and duration of treatment), results, and tertiary outcomes, as well as the small number of studies found with respect to this important issue.
文摘Purpose: To investigate the efficacy of uterine arterial embolization (UAE) in patients with post-partum hemorrhage (PPH). Materials and Methods: The subjects were 40 women (mean age, 33 years;age range, 21 - 42 years) who underwent UAE for PPH at two institutes from June 2001 to May 2011. The rates of clinical success (avoidance of hysterectomy) and complications were calculated. Differences in related factors between primary PPH and secondary PPH and between caesarean section and vaginal delivery were examined. The risk factors associated with hysterectomy were also examined. Results: The overall clinical success rate was 90% (93% of primary PPH, 77% of secondary PPH, and 87.5% of PPH with cesarean section), and the overall complication rate was 10%. There were significant differences in time to PPH (P < 0.0001) and in blood infusion after UAE (P = 0.0158) between subtypes of primary and secondary PPH and in blood infusion before UAE (P = 0.0052) between delivery methods. The significant factors associated with hysterectomy were cesarean section (P = 0.02), severe PPH (>1000 mL bleeding, P = 0.03), and embolization of non-uterine arteries (P = 0.02).
文摘Objective: To evaluate the management process and the guidelines for management of postpartum hemorrhage due to uterine atony at the General Hospital Vienna, Medical University Vienna. Material and Methods: A retrospective analysis was carried out on all 24 cases of postpartum hemorrhage due to uterine atony with an estimated blood loss of more than 800 mL, in which standardized guidelines were obtained. We included all women who gave birth at the General Hospital of Vienna, the Medical University Vienna, during the period from January 1st 2003 and December 31st 2009 and who suffered blood loss 800 mL at minimum due to uterine atony. Results: The guidelines were in use for 14% - 71%. The average blood loss of the 24 cases with uterine atony was 1342 mL. Conclusion: The management process of postpartum hemorrhage due to uterine atony deviates from the hospital’s guidelines in many cases.
文摘Background: Blood loss is one of the important complications during cesarean section (CS). Previous reports have shown that misoprostol is effective in reducing blood loss during and after CS. However, the optimum time for its administration to decrease the amount of PPH is still under discussion. Objective: To compare the effect of preoperative and postoperative administration of sublingual misoprostol (400 μg) in reducing the amount of blood loss during and 24 hours after CS. Setting: Obstetrics and Gynecology Department, Faculty of Medicine, Assiut University, Assiut, Egypt, between January 2017 and July 2018. Study Design: A prospective, randomized clinical trial. Methods: Four-hundred thirty women fulfilling the inclusions criteria: elective lower segment CS at term (≥37 weeks) with normal fetal heart tracing who accepted to participate in the study. Patients were divided into two groups;Patients assigned to group 1 received 400 μg sublingual misoprostol immediately after urinary catheterization and before skin incision, while patients assigned to group 2 received sublingual misoprostol immediately after skin closure. The primary outcome was the estimation of intraoperative and postoperative blood loss for 24 hours. Results: There was a significant reduction in the intraoperative blood loss in group 1 compared with group 2 (403.51 ± 72.99 vs. 460.99 ± 74.66 ml, respectively). Also, there was a significant reduction in postoperative blood loss in group 1 compared with group 2 with a statistical significance (169.45 ± 12.03 vs. 195.77 ± 13.34 ml, respectively). Postoperative hemoglobin and Hematocrit values were significantly higher in group 1 compared with group 2. Conclusions: Preoperative administration of sublingual misoprostol (400 μg) during CS is better than postoperative administration as it is associated with a reduction in the amount of intraoperative and postoperative blood loss and drop in hemoglobin level.
文摘Objective:To explore the effect of carbetocin in preventing postpartum hemorrhage caused by uterine inertia.Methods: A total of 256 puerpera with single full-term delivery who were admitted in our hospital from May, 2015 to May, 2016 were included in the study and divided into the vaginal delivery group and cesarean section group with 128 cases in each group according to the delivery ways. According to the medication, each group was divided into the carbetocin group and oxytocin group with 64 cases in each group. After fetus delivery, the puerpera in the carbetocin group were given intravenous injection of carbetocin (100μg), while the puerpera in the oxytocin group were given intravenous injection of oxytocin (10 U)+0.9% NaCl (500 mL) for 2 h. The amount of bleeding at delivery, 2 h and 24 h after delivery in each group was observed. A volume of 5 mL elbow venous blood before delivery and 24 h after delivery was extracted. The automatic blood cell analyzer was used to detect the decreased value of 24 h hemoglobin in each group. The coagulation detector was used to detect PT, APTT, and FIB before delivery and 24 h after delivery. The blood pressure and heart rate before and after medication in each group were observed.Results: The amount of bleeding at delivery, 2 h and 24 h after delivery in the carbetocin group was signiifcantly less than that in the oxytocin group (P<0.05). The decreased value of 24 h hemoglobin after delivery in the carbetocin group was signiifcantly less than that in the oxytocin group (P<0.05). The indicators of coagulation function 24 h after delivery in each group were not signiifcantly changed (P>0.05). The heart rate and blood pressure after medication in each group were not significantly changed when compared with before medication (P>0.05).Conclusions:Carbetocin can effectively prevent the postpartum hemorrhage caused by uterine inertia, and is safe and effective in application of vaginal delivery and cesarean section;therefore, it deserves to be widely recommended in the clinic.

文摘Objective: The assessment indicators of postpartum hemorrhage(PPH) were systematically reviewed to explore their relationship with blood loss as an early warning sign to identify potential PPH for prompt intervention.Methods: A systematic literature search of 9 databases was conducted according to inclusion and exclusion criteria using a comprehensive strategy. Strengthening the Reporting of Observational Studies in Epidemiology(STROBE) strategy was chosen as the tool for quality assessment of included studies, and data concerning the basic study characteristics and assessment indicators were extracted.Results: Eleven studies were included in this review. The assessment indicators in different reports covered heart rate, blood pressure, placental and birth canal check, hemoglobin(Hb), hematocrit(HCT),coagulation function tests, hemodynamic parameters and arterial blood gas, but no data on the assessment of postpartum uterine contraction were found. The relationship between indicators and blood loss varies.The overall quality of 9 manuscripts was comparatively high or moderate, and 2 were rated as low.Conclusions: The association between blood loss and clinical symptoms is not conclusive based on the present studies, and specific cut-off points could not be formulated to determine the approximate amount of blood loss. However, some cut-off points can be considered warning signs for the need of advanced interventions, such as heart rate, prothrombin time, and placental implantation. Further research on comprehensive assessment and cut-off points should be performed such that birth attendants can distinguish PPH as early as possible.

文摘Objective:To discuss the effect of Hemabate combined with packing therapy on the systemic stress response in patients with postpartum hemorrhage after placenta previa cesarean section. Methods:70 patients with postpartum hemorrhage after placenta previa cesarean section who were treated in Chengdu Women & Children's Central Hospital between January 2014 and February 2017 were collected and then divided into the control group (n=35) who received uterine packing therapy and the observation group (n=35) who received Hemabate combined with packing therapy according to random number table. Serum levels of oxidative stress indexes and stress hormones immediately after operation and 24 h after operation were compared between two groups of patients.Results: Immediately after operation and 24 h after operation, serum oxidative stress indexes ROS and MDA levels of observation group were significantly lower than those of control group while SOD, GSH-px and CAT levels were significantly higher than those of control group, and serum stress hormones NE, E and Cor levels were significantly lower than those of control group.Conclusion: Hemabate combined with packing therapy can effectively reduce systemic stress response in patients with postpartum hemorrhage after placenta previa cesarean section, is a more ideal way of the bleeding.
