老年腹部手术患者全身麻醉后肺部感染的病原学分析

Etiological analysis of pulmonary infections in elderly patients with abdominal surgery after general anesthesia

目的探讨老年腹部手术患者全身麻醉后肺部感染的病原学特征,为肺部感染预防措施的制定提供有针对性的参考依据。方法选取2013年12月-2014年12月医院收治的全身麻醉老年腹部手术患者214例为研究对象,其中46例发生肺部感染,对其肺部感染因素研究,数据采用SPSS 17.0软件进行统计分析。结果全身麻醉老年腹部手术患者214例中,发生肺部感染的患者共计46例,肺部感染率为21.50%;共检出病原菌46株,以革兰阴性菌为主,共28株占60.87%;侵入性操作、呼吸道疾病和抗菌药物应用是导致肺部感染发生的独立危险因素(P<0.05)。结论老年腹部手术全身麻醉患者的肺部感染发病率较高,患者感染病原菌以革兰阴性菌为主,临床上应针对上述研究结果,采取针对性预防措施,以降低肺部感染率。

OBJECTIVE To explore the etiological characteristics of pumonary infections in elder patients after abdominal surgery with general anesthesia,so as to provide targeted reference for the development of lung infection prevention measures.METHODS Totally 214 patients who received clinical abdominal surgery with general anesthesia from Dec.2013 to Dec.2014 were chosen as the research objects.Among them,46 cases proved to have pumonary infections.The risk factors of pumonary infections were analyzed statistically by SPSS 17.0.RESULTS In the 214 elderly patients with abdominal surgery,46 cases got pulmonary infections,and the pulmonary infection rate was 21.50%.A total of 46 strains of pathogens were isolated,mainly gram-negative bacteria with 28 strains accounting for 60.87%.Invasive operation,respiratory tract diseases and antibiotics were proved to be independent risk factors（P〈0.05）.CONCLUSIONThe abdominal surgery in elderly patients with general anesthesia has a higher incidence of causing lung infections.Gram-negative bacteria are the main pathogen causing lung infections.In the clinical treatment,the targeted preventive measures should be taken to reduce the incidence of lung infection.
