However, the curative treatment is surgery. Trans-urethral resection of the prostate (TURP) represents the reference surgical technique when the technical platform is correct. In Bouaké, the FREYER HRYNTCHACK trans vesical approach is the technique used in our department. It sometimes leads to complications that can be life-threatening. The general objective of this work was to describe the morbidity and mortality of trans-bladder adenomectomy and their management at the Bouaké University Hospital. Material and Methods: This is a retrospective descriptive study carried out at the Bouaké Teaching Hospital over a period of 5 years from January 2016 to December 2022. It involved 150 patients operated on for BPH by the trans vesical route and who experienced postoperative complications. The parameters studied were age, postoperative complications, treatment, and mortality. Results: The mean age of the patients was 67.2 ± 7.37 years. Hemorrhage was the main immediate complication. Parietal suppuration, in 48% of cases, was the most common secondary complication, followed by vesicocutaneous fistula (18%), orchiepididymitis (15.33%) and urinary leakage (3.33). Late complications were: retrograde ejaculation in 73.33%, urethral stricture (10.66%) and sclerosis of the compartment (6.66%). Mortality was 1.33%. Conclusion: Post-operative complications of adenomectomies according to Freyer Hrynstchak remain dominated by infections. However, postoperative hemorrhage remains the surgeon’s fear because it can cause the death of the patient. 展开更多

There have been increasing concerns regarding the safety of perioperative anti-tumour necrosis factor (anti-TNF) α agents. We performed a literature review to evaluate the post-operative complications associated with perioperative anti-TNF use in patients with inflammatory bowel disease. A comprehensive review was performed with a literature search utilizing Pub Med, Cochrane, OVID and EMBASE databases according to published guidelines. To date, there are only data for infliximab. There are three published studies which have assessed post-operative complications with perioperative infliximab use in patients with Crohn' s disease (CD), four studies in ulcerative colitis (UC) patients, and one study on both CD and UC patients. Two out of the three studies in CD patients showed no increased post-operative complications associated with perioperative infliximab. Two out of four studies in UC patients also did not show an increase in post-operative complications, and the combined study with CD and UC patients did not show an increased risk as well. Studyresults could not be combined secondary to significant differences in study designs, patient population and definition of their endpoints. There appears to be a risk of post-operative complications associated with TNF therapy in some patients. Based on these data, careful patient selection and prospective data collection should be performed. 展开更多

This paper shows how a public eye and research hospital in Turkey initiated Six Sigma principles to reduce the number of complications occurring after penetrating keratoplasty surgeries. Data were collected for nine years. To analyse the complications among 55 patients (59 eyes) underwent penetrative keratoplasty, main tools of Six Sigma’s Define-Measure-Analyze-Improve-Control (DMAIC) improvement cycle such as SIPOC table and Failure, Mode and Effect Analysis (FMEA) were implemented. Sources and root causes of eleven types of complications were identified and reported. For a successful penetrating keratoplasty surgery patient’s anatomy, suitability of donor cornea, experience of ophthalmic surgeon, sterilization and hygiene, and performance of the equipment were determined to be the “critical-to-quality” factors. The complication with the highest hazard score was found to be the glaucoma. The process sigma level of the process was measured to be 3.1418. The surgical team concluded that all types of post-operative complications should be significantly reduced by taking the necessary preventive measures. 展开更多

The Oral and maxillofacial region is one of the complex regions of the body considering the vast anatomical structures that are found in this region;head and neck surgery has potential for many complications, yet inadequate information on occurrence of post-operative complications in oral and maxillofacial surgeries in our setting has been documented. The aim of this study was to determine the occurrence of common early post-operative complications after oral and maxillofacial surgery in relationship to the underlying systemic condition. A descriptive postoperative study was done whereby patients who underwent oral and maxillofacial surgery were included. The included patients were those who underwent surgery for different pathological conditions, trauma, developmental/congenital conditions and inflammatory conditions to mention few. Demographic data, complications developed within one week post operative, and underlying systemic comorbidities before and after surgery were documented and analysed. A total of 102 patients were included in the study. The mean age of participants was 30.00 ± 17.01 years with a range of 2 to 81 years. Majority 43.1% (n = 44) had benign tumors with a leading diagnosis of ameloblastoma. In general, the most common complications which were noted in the cases included Pain 98% (n = 100) and Post-operative Swelling 97.1% (n = 99). The presence of underlying systemic comorbid conditions has a significant role in occurrence of some severe complications. The occurrence of complications does increase the duration of stay in the hospital hence increasing cost of treatment for which bearers are both patients and the hospital. 展开更多

Objective The aim of the study was to evaluate catheter-related infection rate(CRIR)for patients receiving minimally invasive esophagectomy(MIE),to identify the optimal catheterization approach and relationship between CRIR and post-operative complications.Methods In total,168 patients with esophageal carcinoma and undergoing MIE combined with preoperative deep venous catheterization(DVC)were analyzed in our institution(Qingdao Municipal Hospital,China),from 2014 to 2018.After completing DVC,catheter-tips together with intraductal venous blood samples were sent to the microbiology lab for bacterial strain culture.CRIR was statistically evaluated for the following clinical variables:gender,age,smoking status,drinking status,past history,tumor location,histologic grade,pathological T,N,and M category,anastomotic location,anastomotic leakage,anastomotic stricture,chylothorax,pneumonia,recurrent laryngeal nerve(RLN)injury,reflux esophagitis,catheterization site,and catheter-locking days.Results Among the 144 patients recruited in our study,105 catheters were inserted into the jugular vein and 39 catheters into the subclavian vein.The median age of these patients was 63 years(range:42–79 years),and the median catheter-locking period was seven days(range:4–21 days).Four catheters were identified with three types of strain colonizations,including Staphylococcus epidermidis,Staphylococcus aureus and Blastomyces albicans.Statistical data showed that patients diagnosed with catheter-related infection were likely to incur anastomotic leakage(66.67%,P<0.001)and pneumonia(27.27%,P<0.001);features such as tumors located in the upper esophagus(13.6%,P=0.003),and over seven catheterlocking days(10.00%,P<0.001)were attributed to a high CRIR.Conclusion Although both jugular and subclavian veins can be catheterized for patients with MIE,DVC is associated with more than seven catheter-locking days and upper esophagectomy,due to high CRIR.Furthermore,catheter-related infection is related to anastomotic leakage and pneumonia. 展开更多

Objective At present,there is no appropriate system to evaluate the severe complications of liver surgery through the preoperative factors.This study aimed to design and verify a risk assessment system for the prediction of severe post-operative complications after a hepatectomy based on the preoperative parameters.Methods A retrospective analysis was performed on 1732 patients who had undergone liver surgery.The severity of the complications was graded by Accordion Severity Grading of post-operative complications.The variables were screened by multivariate analysis,and graded scores were assigned to the selected variables.A logistic regression equation was used to form the liver operation risk formula(LORF)for the prediction of severe post-operative complications.The LORF was verified by the receiver operating characteristic(ROC)curve.Results The multivariate correlation analysis revealed the independent influencing factors of the severe post-operative complications of liver surgery were Child-Pugh grade(OR=4.127;P<0.001),medical diseases requiring drug treatment(OR=3.092;P<0.001),the number of liver segments to be removed(OR=2.209;P=0.006),organ invasion(OR=4.538;P=0.024),and pathological type(OR=4.023;P=0.002).The binomial logistic regression model was established to obtain the calculation formula(LORF)of the severe complication risk.The area under the ROC curve(AUC)of the LORF was 0.815.The cut-off value of the expected probability of severe complications was 0.3225(32.25%).Furthermore,in the validation data set,the corresponding AUC of the LORF was 0.829.Conclusion As a novel and simplified assessment system,the LORF could effectively predict the severe post-operative complications of liver surgery through the preoperative factors,and therefore it could be used to evaluate the risk of severe liver surgical complications before surgery. 展开更多

BACKGROUND Neoadjuvant therapy(NAT)is becoming increasingly important in locally advanced rectal cancer.Hence,such research has become a problem.AIM To evaluate the downstaging effect of NAT,its impact on postoperative complications and its prognosis with different medical regimens.METHODS Seventy-seven cases from Shanghai Ruijin Hospital affiliated with Shanghai Jiaotong University School of Medicine were retrospectively collected and divided into the neoadjuvant radiochemotherapy(NRCT)group and the neoadjuvant chemotherapy(NCT)group.The differences between the two groups in tumor regression,postoperative complications,rectal function,disease-free survival,and overall survival were compared using theχ2 test and Kaplan-Meier analysis.RESULTS Baseline data showed no statistical differences between the two groups,whereas the NRCT group had a higher rate of T4(30/55 vs 5/22,P<0.05)than the NCT groups.Twelve cases were evaluated as complete responders,and 15 cases were evaluated as tumor regression grade 0.Except for the reduction rate of T stage(NRCT 37/55 vs NCT 9/22,P<0.05),there was no difference in effectiveness between the two groups.Preoperative radiation was not a risk factor for poor reaction or anastomotic leakage.No significant difference in postoperative complications and disease-free survival between the two groups was observed,although the NRCT group might have better long-term overall survival.CONCLUSION NAT can cause tumor downstaging preoperatively or even complete remission of the primary tumor.Radiochemotherapy could lead to better T downstaging and promising overall survival without more complications. 展开更多

AIM: To investigate the impact of different surgical techniques on post-operative complications after colorectal resection for endometriosis.METHODS: A multicenter case-controlled study using the prospectively collected data of 90 women(22 with and 68 without post-operative complications) who underwent laparoscopic colorectal resection for endometriosis was designed to evaluate any risk factors of post-operative complications. The prospectively collected data included: gender, age, body mass index, American Society of Anesthesiologists risk class, endometriosis localization(from anal verge), operative time, conversion, intraoperative complications, and post-operative surgical complications such as anastomotic dehiscence, bleeding, infection, and bowel dysfunction.RESULTS: A similar number of complicated cases have been registered for the different surgical techniques evaluated(laparoscopy, single access, flexure mobilization, mesenteric artery ligation, and transvaginal specimen extraction). A multivariate regression analysis showed that, after adjusting for major clinical, demographic, and surgical characteristics, complicated cases were only associated withendometriosis localization from the anal verge(OR = 0.8, 95%CI: 0.74-0.98, P = 0.03). After analyzing the association of post-operative complications and each different surgical technique, we found that only bowel dysfunction after surgery was associated with mesenteric artery ligation(11 out of 44 dysfunctions in the mesenteric artery ligation group vs 2 out of 36 cases in the no mesenteric artery ligation group; P = 0.03).CONCLUSION: Although further randomized clinical trials are needed to give a definitive conclusion, laparoscopic colorectal resection for deep infiltrating endometriosis appears to be both feasible and safe. Surgical technique cannot be considered a risk factor of post-operative complications. 展开更多

Obstructive sleep apnea has been linked to higher rates of post-operative complications in some studies. We examined the prevalence of obstructive sleep apnea and its impact on post-operative complications in 125 patients (21 prospective, 104 retrospective) undergoing various elective outpatient surgeries at our institution. Ten percent of these patients had OSA, and half of them were on continuous positive airway pressure therapy (CPAP). Patients who were on CPAP as outpatients received CPAP post-operatively as well. No patients died, and the prevalence of post-operative complications was low. There was no difference in complication rates between patients with and without OSA. We also review the existing literature on this subject and make practical recommendations regarding pre-operative evaluation and post-operative management of these patients for practicing internists and surgeons based on the current literature. 展开更多

This study is a prospective trial comparing the incidence of post-operative complications to fluid status in patients undergoing coronary artery bypass grafting (CABG) surgery. One hundred and nine subjects undergoing CABG surgery at the Jewish general hospital were recruited over a 5 months period in the year 2006. All of the patients underwent CABG surgery “on pump”. Post operative fluid overload was measured by weight gain. Using logistic regression with complications (major vs. minor only/none) as an outcome and fluid overload as a covariate, the risk of major complications significantly increases for fluid overload ≥5 kg compared to 1 - 5 kg (p < 0.001), while the risk for ≤1 kg is not significantly different from 1 - 5 kg. Also, the risk of major complications significantly (p = 0.012) increases for days with fluid overload ≥5 days in comparison to ≤1 day. 展开更多

Objective: The Surgical Apgar Score (SAS) is a tool for intraoperative stratification of the risk of serious complications in the early postoperative period. It varies from 0 to 10 points divided into three risk categories (0 to 4 high, 5 to 7 moderate, 8 to 10 low). The aim of the study was to evaluate its relevance in predicting the appearance of these complications. Material and methods: This descriptive and analytical study was carried out at the “Laquintinie” Hospital in Douala and at the Central Hospital in Yaounde, Cameroon. The main data were collected on a population of patients over 18 years old and recorded on a survey form. They consisted of variables of main interest and exposure variables. Univariate and multivariate statistical analysis using top-down logistic regression models made it possible to evaluate the association of each variable of main interest and each exposure variable. The association was significant at P Results: Of the 88 patients studied, the SAS was 3 hours. In multivariate, this link persisted only and strongly for the SAS OR (IC) 0.1 (0.1 - 0.2) and p = 000. Conclusion: The study found a specific and powerful link between the SAS score < 4 and the occurrence of complications in the early postoperative period, in favor of its relevance in predicting them. 展开更多

BACKGROUND Tourniquets are commonly used in elective extremity orthopaedic surgery to reduce blood loss,improve visualization in the surgical field,and to potentially reduce surgical time.There is a lack of consensus in existing guidelines regarding the optimal tourniquet pressure,placement site,and duration of use.There is a paucity of data on the relationship between the site of a tourniquet and postoperative pain in foot and ankle surgery.AIM To explore the relationship between tourniquet site and intensity of post-operative pain scores in patients undergoing elective foot and ankle surgery.METHODS Retrospective analysis of prospectively collected data on 201 patients who underwent foot and ankle surgery in a single institution was undertaken.Intraoperative tourniquet duration,tourniquet pressure and site,and postoperative pain scores using Visual Analogue Score were collected in immediate recovery,at six hours and at 24 h post-op.Scatter plots were used to analyse the data and to assess for the statistical correlation between tourniquet pressure,duration,site,and pain scores using Pearson correlation coefficient.RESULTS All patients who underwent foot and ankle surgery had tourniquet pressure of 250 mmHg for ankle tourniquet and 300 mmHg for thigh.There was no correlation between the site of the tourniquet and pain scores in recovery,at six hours and after 24 h.There was a weak correlation between tourniquet time and Visual Analogue Score immediately post-op(r=0.14,P=0.04)but not at six or 24 h post-operatively.CONCLUSION This study shows that there was no statistically significant correlation between tourniquet pressure,site and postop pain in patients undergoing foot and ankle surgery.The choice of using a tourniquet is based on the surgeon's preference,with the goal of minimizing the duration of its application at the operative site. 展开更多

Liver transplantation is the primary therapeutic intervention for end-stage liver disease.However,vascular complications,particularly those involving the hepatic artery,pose significant risks to patients.The clinical manifestations associated with early arterial complications following liver transplantation are often non-specific.Without timely intervention,these complications can result in graft fai-lure or patient mortality.Therefore,early diagnosis and the formulation of an op-timal treatment plan are imperative.Ultrasound examination remains the pre-dominant imaging modality for detecting complications post liver transplan-tation.This article comprehensively reviews common causes and clinical present-ations of early hepatic artery complications in the post-transplantation period and delineates abnormal sonographic findings for accurate diagnosis of these con-ditions.Overall,ultrasound offers the advantages of convenience,safety,effect-iveness,and non-invasiveness.It enables real-time,dynamic,and precise evalua-tion,making it the preferred diagnostic method for post-liver transplantation assessments.INTRODUCTION Liver transplantation stands as the primary therapeutic approach for end-stage liver disease.Continuous advancements in surgical techniques and the application of novel immunosuppressive agents contribute to ongoing improvements in the success rate and overall survival in patients undergoing liver transplantation procedures.Despite these advan-cements,vascular complications,particularly those involving the hepatic artery,pose significant risks to patients.During the early stages following liver transplantation(within the first 30 d),proper hepatic artery function is crucial for hepatic arterial blood flow.During later stages,collateral circulation,including arteries such as the phrenic artery,right gastric artery,and gastroduodenal artery,becomes important for maintaining hepatic blood supply.It is now understood that the establishment of effective collateral circulation is pivotal for determining the prognosis of hepatic artery complic-ations.The clinical manifestations of these complications are closely linked to factors such as timing,severity,and the specific type of onset.Insufficient hepatic arterial blood flow can lead to abnormal liver function,hepatic infarction,and the formation of hepatic abscesses.Additionally,since the hepatic artery is the sole blood supply to the biliary tract,hepatic artery-related ischemia may result in biliary stricture,obstruction,and the formation of bile ducts.Ultrasound examination remains the primary imaging modality for diagnosing complications post liver transplantation.This article comprehensively reviews common causes and clinical presentations of early hepatic artery complications in the post-transplantation period and outlines abnormal sonographic findings for accurately diagnosing these conditions.NORMAL HEPATIC ARTERY During the intraoperative phase,an ultrasound examination is typically conducted to evaluate the hepatic artery anas-tomosis.The normal internal diameter of the hepatic artery typically ranges from 2 to 5 mm.Two strong echo points are typically identified near the anastomosis.To assess blood flow dynamics,peak systolic velocity,end-diastolic velocity,and resistance index are measured at the donor and recipient sides of the anastomosis following angle correction.Anastomotic stenosis presence and severity can be evaluated by comparing the velocity at the anastomotic site with that at the recipient side.Postoperatively,direct visualization of the anastomosis site through gray ultrasound scans is often challenging.The surgical approach has a significant impact on the proper hepatic artery’s position,resulting in a lower overall success rate of continuous visualization.Color Doppler ultrasound is primarily employed to trace the artery’s path,and spectral measurements are taken at the brightest position of the Color Doppler blood flow signal,primarily used to identify the presence of high-speed turbulence.Hepatic artery spectrum examination plays a crucial role,as a favorable arterial spectral waveform and appropriate hepatic artery flow velocity typically indicate a successful anastomosis,even in cases where the hepatic artery anastomosis cannot be directly visualized by ultrasound.The hepatic artery runs alongside the portal vein,often selected as a reference due to its larger inner diameter.A normal hepatic artery spectrum displays a regular pulsation pattern with a rapid rise in systole and a slow decline in diastole.Parameters for assessing hepatic artery resistance include a resistance index between 0.5 to 0.8 and an artery systolic acceleration of less than 80 ms.Instantaneous increases in the resistance index(RI>0.8)often occur within 2 d after surgery,followed by a subsequent return to normal hepatic arterial parameters.It has been established that the maximum blood flow velocity during systole in the hepatic artery should not exceed 200 cm/s[1]. 展开更多

BACKGROUND Due to the complexity and numerous comorbidities associated with Crohn’s disease(CD),the incidence of postoperative complications is high,significantly impacting the recovery and prognosis of patients.Consequently,additional stu-dies are required to precisely predict short-term major complications following intestinal resection(IR),aiding surgical decision-making and optimizing patient care.AIM To construct novel models based on machine learning(ML)to predict short-term major postoperative complications in patients with CD following IR.METHODS A retrospective analysis was performed on clinical data derived from a patient cohort that underwent IR for CD from January 2017 to December 2022.The study participants were randomly allocated to either a training cohort or a validation cohort.The logistic regression and random forest(RF)were applied to construct models in the training cohort,with model discrimination evaluated using the area under the curves(AUC).The validation cohort assessed the performance of the constructed models.RESULTS Out of the 259 patients encompassed in the study,5.0%encountered major postoperative complications(Clavien-Dindo≥III)within 30 d following IR for CD.The AUC for the logistic model was 0.916,significantly lower than the AUC of 0.965 for the RF model.The logistic model incorporated a preoperative CD activity index(CDAI)of≥220,a diminished preoperative serum albumin level,conversion to laparotomy surgery,and an extended operation time.A nomogram for the logistic model was plotted.Except for the surgical approach,the other three variables ranked among the top four important variables in the novel ML model.CONCLUSION Both the nomogram and RF exhibited good performance in predicting short-term major postoperative complic-ations in patients with CD,with the RF model showing more superiority.A preoperative CDAI of≥220,a di-minished preoperative serum albumin level,and an extended operation time might be the most crucial variables.The findings of this study can assist clinicians in identifying patients at a higher risk for complications and offering personalized perioperative management to enhance patient outcomes. 展开更多

BACKGROUND Patients not only experience symptoms caused by cancer but also suffer from the accompanying psychological pain.Therefore,these patients do not have high quality of life.According to the World Health Organization,the incidence of leukemia in China in 2020 was 5.1/100000,the mortality rate was 3.3/100000,and the prevalence rate was 16.7/100000.Therefore,it is important to examine the influence of comorbid subthreshold depressive symptoms on leukemia patients.AIM To determine the impact of comorbid subthreshold depressive symptoms on cancer-related fatigue and complications in leukemia patients,thereby providing a basis for early diagnosis and treatment in clinical practice.METHODS A questionnaire survey was conducted among leukemia patients admitted to a tertiary hospital in Xi'an,Shaanxi Province,China,from August 2022 to December 2023.Patients with a score>16 on the Chinese Classification of Mental Disorders(CCMD-3)and a Hamilton Depression Rating Scale score of 8-17 were classified as the subthreshold depressive group(n=95),while 100 leukemia patients admitted during the same period were classified as the control group.Data were collected using Epidata 3.1 software,and comparisons were made between the two groups regarding general clinical data,the Piper Fatigue Scale(PFS),the Pittsburgh Sleep Quality Index(PSQI),the Numeric Rating Scale for pain assessment,laboratory indicators,and the occurrence of complications.RESULTS In this survey,120 leukemia patients with depression were preliminarily screened,95 patients with subthreshold depression were ultimately selected as the subthreshold depression group,and 100 leukemia patients admitted during the same period were enrolled as the normal group.Comparison of basic clinical data between the two groups revealed no significant differences in age,sex,body mass index,cognitive function,or comorbidity with other chronic diseases.However,there were statistically significant differences in the use of radiotherapy and regular exercise between the two groups(P<0.05).Comparisons of scales and laboratory indicators revealed no significant differences in albumin or PSQI scores between the two groups,but there were statistically significant differences in pain scores,PSQI scores,PFS scores,hemoglobin levels,and C-reactive protein levels(P<0.05).Spearman’s correlation analysis indicated that cancer-related fatigue was correlated with age,hemoglobin levels,C-reactive protein levels,pain,and regular exercise among leukemia patients with subthreshold depression.Multivariate regression analysis revealed that advanced age,combined radiotherapy,pain,and low hemoglobin levels were risk factors for cancer-related fatigue in leukemia patients with comorbid subthreshold depression,while regular exercise was a protective factor against cancer-related fatigue.Follow-up comparisons revealed a significantly lower overall incidence of complications in the control group(4%)than in the depressive group(24.21%;P<0.001).CONCLUSION Leukemia patients with comorbid subthreshold depressive symptoms experience more severe cancer-related fatigue and a higher incidence of complications.These findings may be related to advanced age,combined radiotherapy,pain,and low hemoglobin levels,while regular exercise may effectively alleviate symptoms. 展开更多

BACKGROUND The nutritional status is closely related to the prognosis of liver transplant re-cipients,but few studies have reported the role of preoperative objective nutri-tional indices in predicting liver transplant outcomes.AIM To compare the predictive value of various preoperative objective nutritional indicators for determining 30-d mortality and complications following liver transplantation(LT).METHODS A retrospective analysis was conducted on 162 recipients who underwent LT at our institution from December 2019 to June 2022.RESULTS This study identified several independent risk factors associated with 30-d mor-tality,including blood loss,the prognostic nutritional index(PNI),the nutritional risk index(NRI),and the control nutritional status.The 30-d mortality rate was 8.6%.Blood loss,the NRI,and the PNI were found to be independent risk factors for the occurrence of severe postoperative complications.The NRI achieved the highest prediction values for 30-d mortality[area under the curve(AUC)=0.861,P<0.001]and severe complications(AUC=0.643,P=0.011).Compared to those in the high NRI group,the low patients in the NRI group had lower preoperative body mass index and prealbumin and albumin levels,as well as higher alanine aminotransferase and total bilirubin levels,Model for End-stage Liver Disease scores and prothrombin time(P<0.05).Furthermore,the group with a low NRI exhibited significantly greater incidences of intraabdominal bleeding,primary graft nonfunction,and mortality.CONCLUSION The NRI has good predictive value for 30-d mortality and severe complications following LT.The NRI could be an effective tool for transplant surgeons to evaluate perioperative nutritional risk and develop relevant nutritional therapy. 展开更多

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. 展开更多

Mechanical complications of myocardial infarction are potentially fatal events that can occur after an acute myocardial infarction. While the introduction of primary percutaneous reperfusion and fibrinolysis has reduced the incidence of these complications to less than 1%. These complications pose significant hemodynamic consequences and necessitate prompt diagnosis. Echocardiography, cardiac magnetic resonance imaging, and computed tomography are valuable tools for establishing an accurate and expedited diagnosis. Consequently, it is imperative to conduct further scientific research to enhance hemodynamic stabilization techniques such as intra-aortic balloon counterpulsation and extracorporeal membrane oxygenation, in addition to exploring new surgical procedures that can reduce mortality resulting from mechanical complications. This article aims to provide a comprehensive review of mechanical complications following myocardial infarction and their correlation with multi-imaging, facilitating a better understanding of these complications. 展开更多
