The incidence of postoperative excessive bleeding and reexploration is relatively high, and it will bring a series of serious complications, such as an additional surgery, a longer intensive care unit stay, longer time on mechanical ventilation, an increase need of allogeneic blood product transfusions and increased mortality. However, the understanding of postoperative excessive bleeding and reexploration in China is significantly different from the international level, and the understanding of postoperative excessive bleeding and reexploration after cardiac surgery in clinical work is still not enough. This review will focus on some problems, such as related factors analysis of postoperative excessive bleeding, hemostatic process optimization and the serious complications of reexploration after cardiac surgery.
ObjectiveTo compare the effectiveness of haemocoagulase agkistrodon and tranexamic acid and sodium chloride in the prevention and treatment of perioperative bleeding in a real world setting. MethodsA research database was constructed based on the records of inpatient visits using haemocoagulase agkistrodon and tranexamic acid and sodium chloride according to the SuValue® database from January 1, 2016 to December 31, 2020. The patients were divided into two groups according to the different interventions. After matching with a 1∶1 propensity score, the effectiveness of two groups was compared. ResultsA total of 858 patients were included in each of the two groups, and there was no statistically significant difference in baseline characteristics between the two groups (P>0.05). Research results showed that patients using haemocoagulase agkistrodon had significantly reduced length of hospital stay, decrease in hematocrit, average estimated surgical bleeding, and decrease in hemoglobin (P<0.01). ConclusionHaemocoagulase agkistrodon has better effectiveness than tranexamic acid and sodium chloride for reducing perioperative blood loss based on current real world evidence.
ObjectiveTo examine the intrauterine residual tissue in patients with prolonged vaginal bleeding after drug abortion by both B-ultrasound and pathology through cleaning the remnant of uterine, in order to investigate the relationship between prolonged vaginal bleeding after medical abortion with mifepristone and the residual tissues (decidua/villi). MethodsBetween June and December 2011, 144 patients with vaginal bleeding after medical abortion were involved in the study. B-ultrasound and pathology through cleaning the remnant of uterine were adopted to study the residual tissue respectively. ResultsBased on the ultrasound results, the difference in residual tissues was statistically significant between patients with bleeding for 15 days or shorter and patients with bleeding for more than 15 days (P<0.05). The pathological results showed that the difference in decidua and villi on the residual tissues was not statistically significant between patients with bleeding for 15 days or shorter and patients with bleeding for more than 15 days (P>0.05). ConclusionAfter drug abortion, the prolonged vaginal bleeding was correlated with intrauterine residual tissues, and was not correlated with whether the residual tissue was villi or decidua.
ObjectiveTo summarize the research progress of CT related to esophageal varices of cirrhotic patients complicated with portal hypertension.MethodsRelevant CT literatures of esophageal varices of cirrhotic patients complicated with portal hypertension were collected to make an review,then summarized the research status and progress of CT in the diagnosis and evaluation of lower esophageal varices.ResultCT had a good correlation with endoscopic diagnosis of esophageal varices, and CT was of great value in evaluating the presence, degree, and risk of esophageal varicose veins, especially in predicting the risk of esophageal varicose veins, which could be used as an effective modality to assist endoscopic examination to a certain extent.ConclusionsCT is an important examination method for esophageal varices, which has important value in diagnosis and evaluation. In the future, more further researches can be carried out to provide more strong and accurate support for the diagnosis and treatment of esophageal varices.
Anemia and coagulopathy are frequently presented in critically ill patients on the intensive care unit. Scientific use of blood products assist the treatment of critically ill patients. However, life-threatening adverse effects are also a risk. In 2020, the European Society of Critical Care Medicine (ESICM) published a clinical practice guideline on transfusion strategies for non-bleeding critically ill adults in an attempt to resolve the transfusion strategy problems of relevant critically ill patients. This paper interprets the key contents in order to assist Chinese clinicians for better understanding and using of the guideline.
Severe trauma is a challenging medical problem. Uncontrolled post-traumatic hemorrhage and traumatic coagulation dysfunction are closely related to the prognosis of these patients. In May 2019, the pan-European, multidisciplinary Task Force for Advanced Bleeding Care in Trauma published the fifth edition of the European guideline on management of major bleeding and coagulopathy following trauma. To assist Chinese in better understanding of the latest developments, this paper translated the main treatment recommendations in the guideline and interpreted the updated content from the fourth edition.
Objective To assess the efficacy and safety of histamine H2 receptor antagonist (H2RA) for the prevention of stress ulcer bleeding (SUB) in critically ill patients. Methods Trials were identified by searching Cochrane Controlled Trials (Issue 4, 2006), MEDLINE (1980 to October 2006),EMbase (1984 to October 2006) and the Chinese Biological Medicine Database (1978 to October), Chinese VIP Database (1989 to October 2006) and Chinese EBM Database. We also handsearched the proceedings of relevant conferences, 5 kinds of important Chinese journals and the references of all included trials. Two reviewers assessed the quality of studies and extracteddata independently. Disagreement was resolved by discussion . The primary outcomes included were incidence of SUB, incidence of nosocomial pneumonia (NP), mortality and adverse events. Secondary outcomes were gastric pH, length of hospital stayand length of ICU stay. RevMan4.2.7 software was used for meta-analyses. Results Sixteen trials involving 2 014 patients were included. Most of the trials were of poor quality. Meta-analyses showed that H2RA significantly less SUB comparedwith patients in the placebo or non-prophylaxis group (RR 0.39, 95%CI 0.28 to 0.56; Plt;0.000 01, NNT=6), but but there was no significant difference in the incidence of clinically important bleeding (RR 0.51 , 95%CI 0.17 to 1.53; P=0.11). No significant difference was observed in the incidence of NP(RR 1.02, 95%CI 0.55 to 1.89,P=0.95). H2RA significantly decreased mortality in comparison with placebo or non-prophylaxis (RR 0.68, 95%CI 0.52 to 0.90; P=0.007, NNT=18). H2RA had a good safety profile. We did not perform meta-analysis for gastric pH due to the methodological limitations. Conclusion H2RA may significantly reduce the incidence of SUB and mortality, but cannot reduce the incidence of clinically important bleeding. Due to the poor quality of included studies, the conclusion should be interpreted cautiously. More randomized controlled trials with sufficient sample size, uniform standards, higher quality and scientifically sound methodology should be performed.
Coronary heart disease with gastrointestinal bleeding is common in clinical practice. The disease is dangerous and has a high mortality rate. This article will review the risk factors for coronary heart disease with gastrointestinal bleeding (including Helicobacter pylori infection, long-term use of antiplatelet drugs and combined anticoagulation drugs), blood transfusion strategies (including hemoglobin transfusion thresholds and platelet transfusion strategies), and the management of antithrombotic drugs after bleeding (including the management of antiplatelet drugs and the management of anticoagulation combined with antiplatelet drugs). The purpose is to provide a theoretical basis for the diagnosis and treatment of coronary heart disease with gastrointestinal bleeding.
Objective To explore the causes and treatment of rebleeding after operation on portal hypertension patients. Methods The clinical data of 41 rebleeding cases underwent the operational between January 2000 and December 2009 in Peking Union Medical College Hospital were retrospectively analyzed. Results All 13 cases who got rebleeding after shunt operation received lienectomy, but for those who got rebleeding after lienectomy, 23 patients received Phemister or modified Phemister or expanded lienectomy and 5 patients received shunt operation. Surgical related complications occurred in 7 cases (17.1%) at 2 weeks after operation, including abdominal bleeding (3 cases), gastrointestinal bleeding (2 cases), and intractable ascites (2 cases). After the follow-up of 3-60 months (mean 39 months), all patients were still alive. During the follow-up, 3 cases of recurrent esophageal varices were observed and one of them got rebleeding.Conclusion The majority of rebleeding after lienectomy tend to be ascribed to the wrong operations chose, while bad operation skill often contribute to the rebleeding after shunt operation, suggesting ideal therapeutic effect for rebleeding can benefit from appropriate operation choose.
Objective To summarize the risk factors, diagnosis, and treatment experience of intra-abdominal bleeding following surgeries for severe acute pancreatitis. Methods A retrospective review was conducted of 347 patients underwent necrosectomy for severe acute pancreatitis between January 2011 and December 2015 at West China Hospital of Sichuan University. Results Of the 347 patients, thirty-eight patients had intra-abdominal bleeding after surgeries, including 5 patients who had twice bleeding. The bleeding positions including splenic vein (n=7), splenic artery (n=2), pancreatic and peripancreatic vessels (n=8), colonic mesangial vessels (n=6), other vessels (n=12), and extensive osmotic bleeding in abdominal cavity (n=7). Hemostatic modes: suture (n=20), compression hemostasis (n=18), transcatheteranerial embolism (n=2), suture and compression hemostasis (n=4), and conservative treatment (n=1). There were 19 dead patients of 38 bleeding patients. There were statistically significant differences between the hemorrhage group and the non-hemorrhage group on gender, acute physiology and chronic health evaluation (APACHEⅡ) scores and modified Marshall scores at admission, interval onset to surgery, surgical approaches, and morbidity (P<0.05). Compared with the non-hemorrhage group, there were more males, higher APACHE Ⅱ scores and modified Marshall scores, longer interval onset to surgery, and higher mortality in the hemorrhage group. Multivariable logistic regression analysis showed that male patients had higher risk of intra-abdominal bleeding (OR=3.980, P=0.004), as the grow of APACHEⅡ scores, the risk of intra-abdominal bleeding increased (OR=1.487, P<0.001). Conclusions We should pay more attention on the male SAP patients as well as patients with multiple organ dysfunction.
