目的:分析肝硬化合并腹腔感染患者病原菌分布情况、营养状况以及免疫功能.方法:以我院在2019年1月至2021年1月收治的肝硬化合并腹腔感染患者58例作为研究对象,对患者予以基本资料搜集和统计,以分析其病原菌分布状况、营养状况以及免疫功能状况.结果:在58例患者中,其均经过腹水常规检查以及细菌培养,白细胞总数与多核细胞异常.且以细菌培养来进行观察时,其病原菌分布以大肠埃希氏菌为主,然后为聚团肠杆菌、溶血性链球菌、变形杆菌.结论:在肝硬化合并腹腔感染患者进行临床检查后,可以确定其以大肠埃希氏菌感染为主,且免疫“,”Objective: to analyze the distribution of pathogens, nutritional status and immune function in patients with liver cirrhosis complicated with abdominal infection. Methods: from January 2019 to January 2021, 58 patients with liver cirrhosis complicated with abdominal infection in our hospital were selected as the research objects. The basic data of the patients were collected and counted to analyze the distribution of pathogenic bacteria, nutritional status and immune function. Results: in 58 patients, all of them underwent routine examination of ascites and bacterial culture, and the total number of white blood cells and polynuclear cells were abnormal.. Conclusion: after the clinical examination of patients with liver cirrhosis complicated with abdominal infection, it can be determined that the main infection is Escherichia coli, and the immune function is seriously decreased, the nutritional status is poor, so it needs to be combined with the examination results for treatment.
