中青年脑梗死患者医院内感染情况探讨

A Study of Nosocomial Infection on Young and Middle-aged Patients with Cerebral Infarction

目的探讨中青年脑梗死患者医院内感染的发生情况。方法采用回顾性分析法对我院2005年8月~2009年8月收治的896例18~45岁脑梗死病例的医院内感染情况进行统计分析。结果本组医院内感染率为9.15%（82/896）,主要感染部位是呼吸道和泌尿道。896例中男625例,发生医院内感染57例（9.12%）;女271例,发生医院内感染25例（9.23%）,不同性别医院内感染率比较差异无统计学意义（χ2=0,P〉0.05）。医院内感染发生时间最短为入院后第3天,最长为入院后第23天,平均11.53 d。住院1、2、3、4周内的医院内感染率分别为2.01%、5.58%、8.26%、9.15%。本组无糖尿病史的807例发生医院内感染52例（6.44%）,有糖尿病史的89例发生医院内感染30例（33.71%）,有无糖尿病史者医院内感染率比较差异有统计学意义（χ2=73.68,P〈0.001）。结论中青年脑梗死患者医院内感染率高于一般疾病,且与糖尿病史密切相关,主要感染部位是呼吸道和泌尿道。

Objective To study the condition of young and middle-aged patients with cerebral infarction and nosocomial infection.Methods With the retrospective analysis method,statistical analysis was done on the condition of nosocomial infection in 896 cerebral-infarction patients aged 18 to 45 treated in our hospital from August 2005 to August 2009.Results In all the patients,the nosocomial infection rate was 9.15%（82/896）,and the infected positions were mainly at respiratory tract and urinary track;Among 896 patients,57 of nosocomial infections were in 625 male patients（9.12%） and 25 in 271 female patients（9.23%）,and the difference was not significant between males and femals（χ2=0,P0.05）.The shortest time of nosocomial infection was 3 days after admission and the longest was 23 days after admission,and the average time was 11.53 d.The nosocomial infection rates in all the patients within the hospital stay of 1,2,3,or 4 weeks were 2.01%,5.58%,8.26%,9.15% respectively.52 patients had nosocomial infection in 807 patients without diabetes（6.44%） but 30 in 89 patients with diabetes（33.71%）,and the difference was significant（χ2=73.68,P0.001）.Conclusion The nosocomial infection rate is higher in young and middle-aged patient with cerebral infarction than that of common diseases,and it is closely related to diabetes.The infected positions are mainly at respiratory and urinary tracts.
