摘  要:目的 研究呼吸机相关性肺炎(VAP)发生的危险因素.方法 采用前瞻性队列研究,对2007年6月至2010年5月武警总医院ICU收治的78例需要经口气管插管机械通气的成年患者进行连续观察.入选病例分别记录患者因素、医源性因素、营养状况等相关的临床因素,并进行多因素Logistic回归分析.结果 78例患者中,VAP发病率23.1%,病死率22.2%;多因素Logistic回归分析发现,预防性抗生素治疗(OR=6.038;95%CI:1.319~27.641; P=0.021),使用糖皮质激素(OR=5.385;95%CI:1.191~24.346;P=0.029),前白蛋白降低(≤69.7 mg/L)(OR=0.975;95% CI:0.956~0.995;P=0.013)差异具有统计学意义.结论 PA降低(≤69.7 mg/L),预防性抗生素治疗和使用糖皮质激素是VAP发生的独立危险因素.Objective To analysis the risk factors in ventilator-associated pneumonia (VAP) in mechanically ventilated patients.Methods Seventy-eight adult inpatients on mechanical ventilation (MV) through oral endotracheal intubation were studied prospectively by observation between June,2007 and May,2010.Clinical associated factors including patients'predisposition related,medical personnel or device related and nutritional state related factors,etc.were recorded and analyzed.Results In 78 ventilated patients,the incidence of VAP was 23.1%,the fatality rate was 22.2%.Preventive antibiotic treatment (OR=6.038; 95% CI:1.319-27.641; P =0.021),applying glucocorticoid (OR =5.385; 95% CI:1.191-24.346; P =0.029) and prealbumin (PA) ≤ 69.7 mg/L (OR =0.975; 95% CI:0.956-0.995 ; P =0.013) were risk factors in VAP.Conclusions The risk factors in VAP were PA ≤ 69.7mg/L,preventive antibiotic treatment and employment of glucocorticoid.
