摘要
目的:研究呼吸机相关性肺炎(VAP)的发病率、病死率、危险因素及病原菌分布,探讨预防措施。方法:对65例机械通气患者的临床资料进行回顾性分析。结果:本组VAP的发生率为43.08%,病死率为46.43%。VAP的发生与年龄、机械通气时间、鼻饲、抑酸剂及抗生素的应用有关。共检出病原菌54株,其中革兰阴性菌45株,占83.33%,前三位致病菌依次为铜绿假单胞菌、嗜麦芽窄食单胞菌和木糖氧化产碱杆菌;革兰阳性菌4株,占7.41%;真菌5株,占9.26%。结论:危险因素的存在与VAP的发生密切相关。主要致病菌为铜绿假单胞菌和嗜麦芽窄食单胞菌。
Objective: To study the morbility, mortality, risk factors and pathogen of ventilator-associated pneumonia (VAP) for the decision of the prevention strategies. Methods: The clinical data of 65 patients received mechanical ventilation were retrospectively analyzed. Results: The morbidity and mortality of VAP were 43.08% and 46.43%. Age, period of mechanical ventilator, nasogastric feeding, use of antiacid and antibiotics were related to the development with VAP. Fifty- four strains of pathogens were isolated from 28 cases with VAP, the percentages of Gram-negative bacilli, Gram-positive cocci and fungi were 83.33%, 7.41% and 9. 26% respectively. Pseudomonas aeruginosa, Stenotrophornonas rnaltophilia and Achrornobacter xylosoxidans were the most common pathogens. Conclusion: The presence of risk factors is correlated with VAP. The main pathogens are Pseudornonas aeruginosa and X. Maltophilia.
