目的 探讨呼吸机相关性肺炎 (VAP)的临床特点 ,为防治 VAP提供科学依据。方法 对 5 2例 VAP患者的临床特点、病原体的构成、药敏资料等进行回顾性分析。结果 本组 VAP的发生率为 4 7.2 %,VAP的发生与年龄、疾病的程度、机械通气的时间、体位及鼻胃管等有关 ;VAP主要病原体为铜绿假单胞菌、不动杆菌、大肠埃希菌及阴沟肠杆菌 ,药敏监测 4种细菌广泛耐药。结论 VAP多发生于老年人 ,死亡率高 ,应引起重视。
Objective To investigate the clinical features of ventilator-associated pneumonia (VAP) and provide a scientific basis for the prevention and treatment of VAP. Methods 52 cases of VAP patients with clinical features, the composition of pathogens, drug susceptibility data were retrospectively analyzed. Results The incidence of VAP in this group was 42.2%. The incidence of VAP was related to age, disease severity, duration of mechanical ventilation, body position and nasogastric tube. The main pathogens of VAP were Pseudomonas aeruginosa, Acinetobacter and Escherichia coli Escherichia coli and Enterobacter cloacae, drug susceptibility monitoring of four kinds of bacteria widely resistant. Conclusion VAP occurred in the elderly, high mortality, deserves attention.
