Risk Factors Of Rebleeding After Acute Varicose Upper Gastrointestinal Bleeding In Yan’an Area

Objective: To provide reference for the risk prediction,treatment and prevention of rebleeding in such patients by collecting basic clinical data and laboratory examination related indicators.Methods: 1.This experiment is a reverse experiment.Based on birth and exclusion criteria,the study collected data on patients admitted to the gastroenteritis and infection unit from the emergency room of the affiliated Hospital of the University Hospital between January 2020 and December 2022.2.Patients were divided into two groups: those who received no blood after treatment(the "bleeding portion")and those who received the treatment(the "blood return portion").There were 110 cases in the bleeding group and 58 cases in the rebleeding group.3.The collected data of the research objects were analyzed by statistical software SPSS27.0.First,the collected data were tested for normality and homogeneity of variance.Measurement data,such as mean accord with normal distribution is used to add and subtract the standard deviation((?)x ± S)said the skewness distribution of data is using the median and interquartile spacing(M ± Q)said.Among them,independent sample T-test was used for variables conforming to normal distribution and homogeneous variances,and corrected T-test was used for variables with inconsistent variances.Nonparametric test was used for variables with non-normal distribution,and chi-square test was used for binary variables.P < 0.05,the difference was significant.The above statistically significant variables were analyzed by binary Logistic regression to analyze the independent risk factors or protective factors for rebleeding.Results: 1.General characteristics of the study object.The 168 participants were 19 to 78 years old,19 to 78 years old.The proportion of patients aged 41-70 years is the largest,up to 74.99%.Most of the patients need blood transfusion treatment.The proportion of patients who have received blood transfusion treatment accounts for 66.67%,and two or more blood products need to be infused.Among them,the number of suspended red blood cells combined with plasma is the largest,49 cases,accounting for 43.8%.From the onset season,the number began to increase in autumn,and the number in winter and spring in the second year was the largest,and gradually decreased after entering summer.2.Influencing factors of rebleeding PT,PT-%,D-Dimer,infusion cryoprecipitate,number of previous bleeding,whether endoscopic treatment has been performed,and whether chronic anemia has been complicated.There are differences among the above indicators.Endoscopic treatment(OR=2.242,95% CI: 1.096-4.587,P=0.027<0.05)is an independent risk factor,and chronic anemia(OR=0.140,95% CI: 0.033-0.595,P=0.008<0.05)is a protective factor.Conclusion: 1.This study found that the risk factors of rebleeding after acute varicose upper gastrointestinal bleeding include PT,PT%,D-Dimer,infusion cryoprecipitate,previous bleeding times,non-chronic anemia,and endoscopic treatment.2.According to Binary logic analysis of the above risk factors,non-endoscopic treatment is an independent risk factor for the risk factors of rebleeding after acute varicose upper gastrointestinal bleeding,and chronic anemia is a protective factor.
