Clinical nursing value of predictive nursing in reducing complications of pregnant women undergoing short-term massive blood transfusion during cesarean section

BACKGROUND Cesarean hemorrhage is one of the serious complications,and short-term massive blood transfusion can easily cause postoperative infection and physical stress response.However,predictive nursing intervention has important clinical significance for it.AIM To explore the effect of predictive nursing intervention on the stress response and complications of women undergoing short-term mass blood transfusion during cesarean section(CS).METHODS A clinical medical record of 100 pregnant women undergoing rapid mass blood transfusion during sections from June 2019 to June 2021.According to the different nursing methods,patients divided into control group(n=50)and observation group(n=50).Among them,the control group implemented routine nursing,and the observation group implemented predictive nursing intervention based on the control group.Moreover,compared the differences in stress res-ponse,complications,and pain scores before and after the nursing of pregnant women undergoing rapid mass blood transfusion during CS.RESULTS The anxiety and depression scores of pregnant women in the two groups were significantly improved after nursing,and the psychological stress response of the observation group was significantly lower than that of the control group(P<0.05).The heart rate and mean arterial pressure(MAP)of the observation group during delivery were lower than those of the control group,and the MAP at the end of delivery was lower than that of the control group(P<0.05).Moreover,different pain scores improved significantly in both groups,with the observation group considerably less than the control group(P<0.05).After nursing,complications such as skin rash,urinary retention,chills,diarrhea,and anaphylactic shock in the observation group were 18%,which significantly higher than in the control group(4%)(P<0.05).CONCLUSION Predictive nursing intervention can effectively relieve the pain,reduce the incidence of complications,improve mood and stress response,and serve as a reference value for the nursing of women undergoing rapid mass transfusion during CS.

Survey on Blood Transfusion Practices among Medical and Paramedical Staff in the Pediatric Unit of the Mohammed VI University Hospital in Marrakesh, Morocco

Blood transfusion is a complex activity, involving many actors. As a high-risk activity, it necessitates the implementation of specific methods for effective control. The safety of blood transfusion is significantly influenced by the beliefs of healthcare workers and organizational factors, constituting two major considerations. We conducted a cross-sectional, descriptive, and analytical survey to examine the knowledge and practices related to transfusion among the medical and paramedical staff at the Pediatric Department (Mother-Child) of CHU Mohammed VI from September 1, 2022, to December 31, 2022. Among the 135 staff members interviewed, only 41% had received training in blood transfusion. A majority (65.2%) of the staff noted that a mismatch in cross-matching led to transfusion complications. Two-thirds (66.7%) identified chills as the primary clinical sign of potential accidents. Regarding elements to monitor during a reaction, hemolysis (78.5%) and temperature (76.3%) were most commonly mentioned. Surprisingly, more than half (53.3%) of the personnel interviewed did not conduct post-transfusion monitoring. This survey highlighted significant deficiencies in knowledge and practices related to transfusion. To address these issues, we recommend implementing guidelines and providing tailored training for the staff, aiming to rectify these deficiencies and enhance overall practices.

The Effect of the Direct Anti-Human Globulin Test on the Clinical Outcome of Patients Receiving Blood Transfusion

Objective:To study the effect of the direct anti-human globulin test on the clinical efficacy of blood transfusion patients.Methods:52 transfused patients were selected for this study,of which 26 cases with positive direct anti-human globulin tests were included in the positive group,and another 26 cases with negative direct anti-human globulin tests were included in the negative group.The apparent efficacy of the patients in the two groups after blood transfusion was compared.Results:After blood transfusion,the apparent efficacy of the negative group was significantly higher,P<0.05;in the positive group,the proportion of the predominantly multi-antibody group was the highest;after blood transfusion,the post-transfusion apparent efficacy of the simple IgG group was higher than that of the multi-antibody group,P<0.05;comparing the intensity of the different antibodies resulted in the 1+group,and the 3+to 4+groups were significantly lower after blood transfusion,P<0.05.Conclusion:The use of the direct antiglobulin test in transfused patients showed that patients with positive results would have better clinical efficacy.Direct anti-human globulin tests will have an impact on the clinical efficacy of blood transfusion in patients with positive results,so it is very important to carry out a direct anti-human globulin test on blood transfusion patients.

Machine Learning for Detecting Blood Transfusion Needs Using Biosignals

Adequate oxygen in red blood cells carrying through the body to the heart and brain is important to maintain life.For those patients requiring blood,blood transfusion is a common procedure in which donated blood or blood components are given through an intravenous line.However,detecting the need for blood transfusion is time-consuming and sometimes not easily diagnosed,such as internal bleeding.This study considered physiological signals such as electrocardiogram(ECG),photoplethysmogram(PPG),blood pressure,oxygen saturation(SpO2),and respiration,and proposed the machine learning model to detect the need for blood transfusion accurately.For the model,this study extracted 14 features from the physiological signals and used an ensemble approach combining extreme gradient boosting and random forest.The model was evaluated by a stratified five-fold crossvalidation:the detection accuracy and area under the receiver operating characteristics were 92.7%and 0.977,respectively.

Risk factors for blood transfusion and its prognostic implications in curative gastrectomy for gastric cancer

BACKGROUND Gastric cancer(GC)is still a prevalent neoplasm around the world and its main treatment modality is surgical resection.The need for perioperative blood transfusions is frequent,and there is a long-lasting debate regarding its impact on survival.AIM To evaluate the factors related to the risk of receiving red blood cell(RBC)transfusion and its influence on surgical and survival outcomes of patients with GC.METHODS Patients who underwent curative resection for primary gastric adenocarcinoma at our Institute between 2009 and 2021 were retrospectively evaluated.Clinicopathological and surgical characteristics data were collected.The patients were divided into transfusion and non-transfusion groups for analysis.RESULTS A total of 718 patients were included,and 189(26.3%)patients received perioperative RBC transfusion(23 intraoperatively,133 postoperatively,and 33 in both periods).Patients in the RBC transfusions group were older(P<0.001),and had morecomorbidities(P=0.014),American Society of Anesthesiologists classification III/IV(P<0.001),and lower preoperative hemoglobin(P<0.001)and albumin levels(P<0.001).Larger tumors(P<0.001)and advanced tumor node metastasis stage(P<0.001)were also associated with the RBCtransfusion group.The rates of postoperative complications(POC)and 30-d and 90-d mortalitywere significantly higher in the RBC transfusion group than in the non-transfusion group.Lowerhemoglobin and albumin levels,total gastrectomy,open surgery,and the occurrence of POC werefactors associated with the RBC transfusion.Survival analysis demonstrated that the RBCtransfusions group had worse disease-free survival(DFS)and overall survival(OS)compared withpatients who did not receive transfusion(P<0.001 for both).In multivariate analysis,RBCtransfusion,major POC,pT3/T4 category,pN+,D1 lymphadenectomy,and total gastrectomywere independent risk factors related to worse DFS and OS.CONCLUSIONPerioperative RBC transfusion is associated with worse clinical conditions and more advancedtumors.Further,it is an independent factor related to worse survival in the curative intentgastrectomy setting.

Impact of perioperative blood transfusion on oncological outcomes in ampullary carcinoma patients underwent pancreaticoduodenectomy

BACKGROUND The effect of perioperative blood transfusion(PBT)on the prognosis of ampullary carcinoma(AC)is still debated.AIM To explore the impact of PBT on short-term safety and long-term survival in AC patients who underwent pancreaticoduodenectomy.METHODS A total of 257 patients with AC who underwent pancreaticoduodenectomy between 1998 and 2020 in the Cancer Hospital,Chinese Academy of Medical Sciences,were retrospectively analyzed.We used Cox proportional hazard regression to identify prognostic factors of overall survival(OS)and recurrencefree survival(RFS)and the Kaplan-Meier method to analyze survival information.RESULTS A total of 144(56%)of 257 patients received PBT.The PBT group and nonperioperative blood transfusion group showed no significant differences in demographics.Patients who received transfusion had a comparable incidence of postoperative complications with patients who did not.Univariable and multivariable Cox proportional hazard regression analyses indicated that transfusion was not an independent predictor of OS or RFS.We performed Kaplan-Meier analysis according to subgroups of T stage,and subgroup analysis indicated that PBT might be associated with worse OS(P<0.05)but not RFS in AC of stage T1.CONCLUSION We found that PBT might be associated with decreased OS in early AC,but more validation is needed.The reasonable use of transfusion might be helpful to improve OS.

The Place of Blood Transfusion in the Management of Obstetric Emergencies in the Gynaecology and Obstetrics Department of the Reference Health Center of Fana (Mali)

This is a prospective and descriptive study carried out at the gynecology and obstetrics department of the reference health center of Fana from 01 May 2019 to 30 November or 7 months. The main objective was to study the role of blood transfusion in the management of obstetric emergencies. During the study period we recorded 434 cases of obstetric emergencies of which 116 cases required an emergency blood transfusion or 26.73%. The most frequently found indications for blood transfusion are hemorrhages of the immediate postpartum 46.6% followed by severe malaria on pregnancy 27.6%. Blood remains the most prescribed and available Labile blood product in the department. Maternal prognosis was improved in 92.2%.

Perioperative blood transfusion decreases long-term survival in pediatric living donor liver transplantation

BACKGROUND The impact of perioperative blood transfusion on short-and long-term outcomes in pediatric living donor liver transplantation(PLDLT)must still be ascertained,mainly among young children.Clinical and surgical postoperative complications related to perioperative blood transfusion are well described up to three months after adult liver transplantation.AIM To determine whether transfusion is associated with early and late postoperative complications and mortality in small patients undergoing PLDLT.METHODS We evaluated the effects of perioperative transfusion on postoperative complications in recipients up to 20 kg of body weight,submitted to PLDLT.A total of 240 patients were retrospectively allocated into two groups according to postoperative complications:Minor complications(n=109)and major complications(n=131).Multiple logistic regression analysis identified the volume of perioperative packed red blood cells(RBC)transfusion as the only independent risk factor for major postoperative complications.The receiver operating characteristic curve was drawn to identify the optimal volume of the perioperative RBC transfusion related to the presence of major postoperative complications,defining a cutoff point of 27.5 mL/kg.Subsequently,patients were reallocated to a low-volume transfusion group(LTr;n=103,RBC≤27.5 mL/kg)and a high-volume transfusion group(HTr;n=137,RBC>27.5 mL/kg)so that the outcome could be analyzed.RESULTS High-volume transfusion was associated with an increased number of major complications and mortality during hospitalization up to a 10-year follow-up period.During a short-term period,the HTr showed an increase in major infectious,cardiovascular,respiratory,and bleeding complications,with a decrease in rejection complications compared to the LTr.Over a long-term period,the HTr showed an increase in major infectious,cardiovascular,respiratory,and minor neoplastic complications,with a decrease in rejection complications.Additionally,Cox hazard regression found that high-volume RBC transfusion increased the mortality risk by 3.031-fold compared to low-volume transfusion.The Kaplan-Meier survival curves of the studied groups were compared using log-rank tests and the analysis showed significantly decreased graft survival,but with no impact in patient survival related to major complications.On the other hand,there was a significant decrease in both graft and patient survival,with high-volume RBC transfusion.CONCLUSION Transfusion of RBC volume higher than 27.5 mL/kg during the perioperative period is associated with a significant increase in short-and long-term postoperative morbidity and mortality after PLDLT.

Distinct risk factors for early and late blood transfusion following pancreaticoduodenectomy

Background: The International Study Group of Pancreatic Surgery(ISGPS) has defined two periods of postpancreatectomy hemorrhage, early(<24 h) and late(>24 h). A previously published Blood Usage Risk Score(BURS) aimed to predict early and late blood transfusion. The primary aim of this study was to define risk factors for early and late blood transfusion after pancreaticoduodenectomy. Secondary aims were to assess the predictive accuracy of the BURS.Methods: In this retrospective observational study, multivariable analyses were used to identify independent risk factors for both early and late blood transfusion. The predictive ability of the BURS was then assessed using a receiver operating characteristic(ROC) curve analysis.Results: Among 628 patients, 99(15.8%) and 144(22.9%) received early and late blood transfusion, respectively. Risk factors for blood transfusion differed between early and late periods. Preoperative anemia and venous resection were associated with early blood transfusion whilst Whipple’s resection(as opposed to pylorus preserving pancreaticoduodenectomy), lack of biliary stent and a narrow pancreatic duct were predictors of late blood transfusion. The BURS was significantly predictive of early blood transfusion,albeit with a modest degree of accuracy(AUROC: 0.700, P < 0.001), but not of late blood transfusion(AUROC: 0.525, P = 0.360). Late blood transfusion was independently associated with increasing severity of postoperative pancreatic fistula(POPF)(OR: 1.85, 3.18 and 9.97 for biochemical, types B and C POPF,respectively, relative to no POPF).Conclusions: Two largely different sets of variables are related to early and late blood transfusion following pancreaticoduodenectomy. The BURS was significantly associated with early, albeit with modest predictive accuracy, but not late blood transfusion. An understanding of POPF risk allows assessment of the need for late blood transfusion.

Severe hyperlipemia-induced pseudoerythrocytosis - Implication for misdiagnosis and blood transfusion: A case report and literature review

BACKGROUND Severe hyperlipemia(SHLE)has an impact on the results of many kinds of laboratory tests.Complete blood count(CBC)examination by automated blood cell counter(ABCC)is a quick and convenient measurement for screening abnormalities of blood cells that are triggered by various pathogenic insults in disease diagnosis and for monitoring changes in the treatment of existing hematological conditions.However,CBC results are frequently affected by many intrinsic and extrinsic factors from blood samples,such as in the setting of hypergammaglobulinemia and certain anticoagulants.SHLE could also affect CBC results.CASE SUMMARY A 33-year-old Chinese male presented with painful foot numbness and abdominal pain.He was initially misdiagnosed as having a myeloproliferative neoplasm(MPN)because of the marked abnormalities in CBC examination by the ABCC.Morphological evaluation of the bone marrow smears and biopsy showed no evidence of MPN.Gene mutations in Breakpoint cluster regions-Abelson murine leukemia viral oncogene homologue 1(BCR-ABL1),Janus kinase 2(JAK2),calreticulin(CALR),myeloproliferative leukemia virus(MPL),and colony-stimulating factor 3 receptor(CSF3R)were negative.Having noticed the thick chylomicron layer on blood samples and the dramatically fluctuating CBC results,we speculated that the fat droplets formed by shaking the blood samples in the setting of SHLE were mistakenly identified as blood cells due to the limited parameters of ABCC.Therefore,we removed a large part of the chylomicron layer and then reexamined the CBC,and the CBC results,as we expected,differed significantly from that of the sample before the chylomicron layer was removed.These significant differences had been validated by the subsequently repeated laboratory tests by measuring dual blood samples that the chylomicron layer was removed in one sample and was not in another,and comparing the CBC results.Computerized tomography reexamination of the upper abdomen revealed an exudative lesion surrounding his pancreas.After intensive consultation,definitive diagnosis was made as recurrent pancreatitis,hyperlipemia and pseudoerythrocytosis.CONCLUSION SHLE may become a potential cause of misdiagnosis of hyperlipemia-related diseases as MPNs and the resultant mistreatment.It may also lead to the misinterpretation of transfusion indications in patients with hematological disorders who critically need blood transfusion for supportive treatment.

Effect of exchange blood transfusion on oxygen saturation of neonates with severe neonatal jaundice by pulse oximetry

Objective:To determine if there was any difference in SpO2 readings during exchange blood transfusion(EBT).Methods:A prospective cross-sectional study of neonates with severe neonatal jaundice requiring EBT was conducted.Oxygen saturation was recorded before,immediately and 15 minutes after EBT by using a pulse oximeter.Results:This study included 30 neonates with 20 males and 10 females.The age ranged from 1 to 12 days with a mean of(5.4±2.9)days.Pre-EBT SpO2 ranged from 90%to 98%with a mean value of(94.3±2.2)%;SpO2 in the end of EBT ranged from 85%to 99%with a mean value of(94.1±3.2)%;SpO2 at 15 minutes after EBT ranged from 77%to 99%with a mean value of(94.8±4.1)%.There was no significant difference between SpO2 values at onset of EBT and either immediately or 15 minutes after EBT(P=0.770 and 0.422,respectively).SpO2 showed no significant difference between neonates who were infused with blood of different storage times(<24 h or≥24 h)at the onset of EBT(P=0.584),immediately(P>0.999)and 15 minutes after EBT(P=0.887).Besides,SpO2 values were compariable in neonates with hematocrit<45%or≥45%at the onset of EBT(P=0.284),immediately(P=0.118)and 15 minutes after EBT(P=0.868).Conclusions:EBT does not affect SpO2 in neonates.

Comparison of Blood Group Molecular Genotyping to Traditional Serological Phenotyping in Patients with Chronic or Recent Blood Transfusion

Objectives: Accurately identifying the Antigens (Ags) on recipient red blood cells (RBCs) is critical in prevention of RBC alloimmunization in chronically transfused patients. The goal of this study was to compare RBC molecular genotyping to serological phenotyping in those patients. Methods: Serological phenotyping and molecular genotyping methods were used to study blood samples from 18 healthy blood donors and 16 transfused patients. Reticulocyte harvesting or hypotonic cell separation was added to recheck RBC phenotypes of the patients with discrepancies between phenotyping and genotyping. Results: No discrepancies were found between the two genotyping methods in all the donors and patients. 1 of 9 sickle-cell disease (SCD) patients and all 3 thalassemia patients demonstrated discrepancies in multiple blood groups between phenotyping and genotyping, which were not corrected by reticulocyte harvesting or hypotonic cell separation. Conclusions: These findings suggest that RBC molecular genotyping is superior to serological phenotyping in chronically transfused SCD or thalassemia patients.

ENHANCEMENT OF TUMOR GROWTH AFTER PARTIAL HEPATECTOMY AND BLOOD TRANSFUSION

Female adult BUF rats (6-8 weeks) received Sham operation (Sham); 70% hepatectomy (PH); Sham or PH with blood transfusion (BT or PH+BT). BUF 7316A hepatoma cells were inoculated subcutaneously in the neck of rats on the operation day. Tumor size was measured from day 7 to 20 after inoculation. Sera and splenic adherent cell harvested on day 5 from Sham and PH rat were added into Mixed Lymphocyte Cultures (MLR). The result showed that tumor growth in PH or BT rats was significantly promoted as compared to that in Sham rats (P<0.01,P<0.05). The most marked enhancement of tumor growth was observed in PH+BT rats (P<0.001). Sera and splenic adherent cell from PH rat significantly inhibited MLR (P<0.05). Those results suggest that partial hepatectomy and blood transfusion are responsible for the enhancement of tumor growth. Some immunosuppressive factor might be produced in the process of liver regeneration, and blood transfusion might have an additive immunosuppressive effect.

Nurses and nursing students’knowledge regarding blood transfusion:A comparative cross-sectional study

Objective:The objective of this study is to measure and compare the knowledge of nursing students and nurses on blood transfusion in an Indian context.Materials and Methods:The present comparative,cross-sectional study enrolled 296 nurses and 177 nursing students through a purposive sampling from a medical university hospital and different nursing institutions.The data were collected in the month of June and July of year 2021,using a self-structured questionnaire.The questionnaire had two sections:Section-I contained demographic data(8 items for nurses and 5 for students)and section-II included 26 items that assessed nurses’and nursing students’knowledge on blood transfusion.Results:Findings indicated that nurses and nursing students had insufficient knowledge about blood transfusion.Nurses,however,had significantly greater total blood transfusion knowledge scores than nursing students(16.51±3.85 vs.12.10±3.28;P<0.001).The marital status(adjusted odds ratio[AOR]=0.456,95%confidence interval[CI]0.244,0.853;P=0.037),educational level(AOR=5.072,95%CI 1.982,9.634(P=0.003);AOR=6.540,95%CI 2.54,16.871;P=0.001)and work experience(AOR=0.216,95%CI 0.067,0.702[P=0.037];AOR=0.331,95%CI 0.135,0.811;P=0.013)were the significant predictors of the level of knowledge among nurses.The attendance in any educational programme on blood transfusion(AOR=0.225,95%CI:0.062,0.818;P=0.041)was a significant predictor of the level of knowledge among nursing students.Conclusion:Nurses and nursing students have unsatisfactory knowledge on blood transfusion;emphasizing the critical need for immediate and successful teaching activities in this area.

Digestive Bleeding by Rupture of Esophageal Varicose Veins and Prognosis Value of Blood Transfusion in the Hepatogastroenterology Department of the Gabriel Toure Hospital

Digestive hemorrhage by rupture of esophageal Varices is common and has a pejorative prognosis in our context. Purpose: The main purpose of this work was to study the digestive bleeding by esophageal varices and prognosis value of blood transfusion in the Hospital of Gabriel Touré. Methodology: It was a prospective study that took place in the service of Hepato-gastroenterology of Gabriel Touré Hospital from June 2016 to May 2017 and from November 2017 to August 2018. Results: At the end of the study, 77 patients met the inclusion criteria out of 1396 patients hospitalized during the same period. Varices bleeding represented a prevalence of 5.5% among hospitalized patients during the same period. The average age of our patients was 46.58 ± 15.09 years. The male sex was more reported in our study with a prevalence of 67.5%. At admission, 63.2% had clinical anemia, 58.4% low arterial pressure and 50.6% hemoglobin rate less than 7 g/dL. Blood transfusion was indicated in 47 patients (61%). The mortality rate was 23.4% and was comparable in both groups (p = 0.0990). Early rebleeding was significantly observed in the case of transfusion (p = 0.0452). Hepatic encephalopathy was the leading cause of death of our patients with 72.2%. Conclusion: Digestive bleeding by esophageal varices is a worsen complication in cirrhosis in hospital setting. Transfusion has not significantly improved the prognosis of our patients.

The Value of Continuous Noninvasive Hemoglobin Monitoring in Intraoperative Blood Transfusion Practice during Abdominal Cancer Surgery

Introduction: Patients undergoing major oncological surgery may suffer from severe bleeding. Sometimes, it is difficult to anesthesiologist to take decision about timing of administration blood products to such patients. The aim of this study is to evaluate the use of continuous noninvasive hemoglobin monitoring as a guide for blood transfusion practice. Methods: One hundred patients undergoing elective abdominal cancer surgeries were randomly allocated into two groups, Group I (n = 50): laboratory Hb was obtained at baseline (immediate preoperative), intraoperative (when to suggest transfusion triggering value) and immediate postoperative. Group II (n = 50): The probe of Masimo for SpHb monitoring was applied immediately after induction of anesthesia at the index finger. Laboratory Hb was obtained at baseline (immediate preoperative), intraoperative (when to suggest transfusion triggering value) and immediate postoperative. Results: A number of transfused units of RBC were significantly lower in SpHb group than in control group (p value 0.05). Conclusion: SpHb monitoring had clinically acceptable absolute and trend accuracy. SpHb monitoring altered transfusion decision making and resulted in decreased RBC utilization and decreased RBC costs while facilitating earlier transfusions when indicated.
