ICU呼吸机相关性肺炎临床相关因素分析

为了探讨呼吸机相关性肺炎（VAP）发生的危险因素，回顾性分析我院ICU机械通气的88例患者的临床资料，按诊断标准分为发生VAP组和未发生VAP组，对两组患者的相关因素及预后进行评价。结果显示，发生VAP组机械通气时间明显长于未发生VAP组（P〈0．05）；两组在年龄、APACHE评分、病死率差异显著（P〈0．05）。因此，机械通气时间是影响VAP发生的重要因素，患者年龄越大，APACHE评分越高，越容易发生VAP。VAP是病情危重的一个表现，发生VAP的患者，病死率高，防治VAP的措施是必要的。

Analysis of Correlation Factors of Ventilator Associated Pneumonia in ICU

To explore the correlation factors about ventilator associated pneumonia （VAP）through analyzing the patients＇ clinical materials. Totally 88 patients admitted to our hospital ICU were divided into two groups： VAP and non-- VAP group,according to the diagnosis criteria. The comparative analysis was performed in clinical characteristics, correlation factors. Patients with VAP showed longer ventilation times（P〈0.05）. Differences were found for age,APACHE Ⅱ values and mortality between two groups（P〈0.05 ）. VAP could be a serious exhibition of death. Preventive measures should be employed.
