摘　　要：目的 分析严重胸部创伤患者呼吸机相关性肺炎(VAP)感染特点及危险因素。方法 通过回顾性调查方式,对浙江省湖州市2家医院严重胸部创伤(SCT)患者VAP感染情况及危险因素进行分析。结果 共调查252例SCT患者,发生VAP 74例,VAP感染率为29.37%。从74例患者痰标本分离病原菌95株,其中革兰阴性菌、革兰阳性菌和真菌检出率分别占80.00%、16.84%和3.16%。多因素分析显示,年龄≥60岁、糖尿病、机械通气天数≥7 d、CONUT评分≥5分和AIS评分>4分是SCT患者发生VAP的独立危险因素。结论 SCT患者发生VAP感染风险较高,感染病原菌以革兰阴细菌为主,临床应针对危险因素制订防控措施。Objective To analyze the characteristics and risk factors of ventilator associated pneumonia(VAP)infection in patients with severe chest traum(SCT).Methods Retrospective analysis was used to analyze the VAP infection situation and risk factors with SCT from 2 hospitals in Huzhou City,Zhejiang Province.Results A total of 252 SCT patients were collected,of which 74 had VAP,with infection rate of 29.37%.95 strains of pathogenic bacteria were isolated from 74 sputum samples,the detection rates of gram negative bacteria,gram positive bacteria and fungi accounting for 80.00%,16.84%and 3.16%respectively.Multivariate analysis showed that the independent risk factors for VAP in SCT patients included age≥60 years,diabetes,days of mechanical ventilation≥7 d,CONUT score≥5 points,AIS score>4 points.Conclusion The incidence of VAP infection is high in SCT patients,and gram negative bacteria is the main pathogen of infection.Effective prevention and control measures should be formulated for independent risk factors.
