机械通气(MV)作为危重病患者呼吸支持强有力手段之一,其常见并发症—机械通气相关性肺炎(VAP)越来越得到人们的重视。据报道,VAP的发病率在9％～68％,而VAP亦常是危重病患者死亡的主要原因之一,其相关病死率可高达50％以上。为提高对VAP的认识,进行有效的防治,我们对我院内科ICU自1997年1月至1998年8月79例MV过程中出现VAP的30例患者进行分析,报告如下。 Mechanical ventilation (MV) is one of the powerful means of respiratory support in critically ill patients. Its common complication, mechanical ventilation-related pneumonia (VAP), is getting more and more attention. It is reported that the incidence of VAP in 9% to 68%, and VAP is often one of the major causes of death in critically ill patients, the related mortality rate can be as high as 50% or more. In order to raise the awareness of VAP and carry out effective prevention and treatment, we analyzed 30 patients with VAP during 79 MV episodes in our hospital ICU from January 1997 to August 1998, and the report is as follows.
