摘要
目的 探讨机械通气相关肺炎 (VAP)的危险因素。方法 选取内科 ICU、外科 ICU、CCU机械通气时间在2 4小时以上 194例患者 ,符合 VAP诊断标准作为 VAP感染组 ,VAP未感染组作为对照组 ,采用单因素分析与多因素分析分别得出 VAP危险因素、独立危险因素。结果 VAP的感染发生率为 2 7.84 %。单因素分析表明慢性肺疾病、先前使用抗生素、气管造口术、急诊手术、机械通气患者仰卧位、鼻胃管、肺动脉插管、胃内容物吸入、年龄≥ 60岁、机械通气时间≥ 5天是 VAP显著性相关因素 ,多因素 L ogistic回归分析表明慢性肺疾病、患者抑卧位、先前使用抗生素、年龄≥ 60岁是 VAP的独立相关因素。不同类型 ICU(MICU、SICU、CCU)患者有不同的VAP感染发生率。CCU患者与内科 ICU患者相比 ,CCU患者 VAP发生率显著偏高。结论 避免 VAP的危险因素是降低
OBJECTIVE To investigate the risk factors relaled to the development of ventilatior associated pneumonia (VAP).METHODS A total of 194 patients required mechanical ventilation for longer than 24 hours from the medical ICU, surgical ICU or cardiothoracic ICU were analized. Comparisosn between groups of VAP and non VAP were made by unifactor analysis and multifactor analysis of logistic regression. RESULTS The incidental rate of VAP was 27.84%. Chronic lung discase, prior antibiotics, supine head posfure and the patient age of more than 60 years were independently associated facfors with VAP. The different ICU patients had different inciednces of VAP. CONCLUSION The results suggest that to avoid risk fctors may be the effeetive measue in lowering the incident rate of VAP.
