ICU中创伤患者院内获得性肺炎危险因素分析

Incidence and risk factors of nosocomial pneumonia of injured patients in intensive care unit

目的 探讨ICU内创伤患者肺炎发病率及其相关因素。方法 采用回顾性调查分析方法 ,对重症监护病房 1997年 10月～ 1998年 10月收入住院的 5 5例创伤患者进行分析。结果 发现ICU内创伤患者有较高的肺炎发病率 (发病率3 1% ) ,高危因素有以下几个方面 :入院时的急性生理评分 ,Glassglow评分 ,严重的胸部损伤 ,住ICU的时间 ,机械通气时间 ,是否留置胃管。结论 充分估计创伤患者的生理评分 ,缩短机械通气时间及ICU内时间 ,减少侵入性操作是预防院内肺炎 (nosocomialpneumonia,NP)主要预防措施。

Objective To study the incidence and risk factors of nosocomial pneumonia (NP) of injured patients in the intensive care unit.Methods 55 injured patients admitted to the ICU from October 1997 to October 1998 were reviewed and analysed retrospectively.Results The incidence of NP of injured patients were high(31%).The risk factors of NP were acute physiologic score>6,Glassglow score<10,severe chest trauma,longer staying time ICU,mechanical ventilation and stomach intubation.Conclusion Restrict and eliminate above risk factors,especially reduced the duration of mechanical ventilator and ICU staying were the primary strategy for prevention of NP.
