目的:探讨重症监护病房(ICU)呼吸机相关性肺炎(VAP)危险因素。方法:回顾性分析2012年1月-2014年1月本院进行机械通气时间在48 h以上的160例急诊危重患者临床资料,以其是否出现肺炎进行分组,出现肺炎的患者为VAP组,68例,未出现肺炎为VAP组,92例,对比两组患者的情况,对治疗组患者进行单因素和多因素的多元回归性逻辑学分析。结果:多因素非条件逻辑学回归分析显示,机械通气时间、侵入性操作、留置胃管、原发性疾病为慢性阻塞性肺疾病(COPD)、使用制酸剂以及APACHEII评分为VAP发病的单独危险因素。结论:对ICU患者进行机械通气,有较高的肺炎发病率,且能够影响其发病的因素有较多,需要采取相应的防护措施。
Objective: To explore the risk factors of ventilator associated pneumonia (VAP) in intensive care unit (ICU). Methods: The clinical data of 160 emergency critically ill patients with mechanical ventilation over 48 hours from January 2012 to January 2014 in our hospital were retrospectively analyzed. Patients with pneumonia were divided into groups according to whether they had pneumonia or not. The patients with pneumonia were VAP group, 68 Cases, no pneumonia was VAP group, 92 cases, the two groups of patients were compared, the treatment group patients were single factor and multivariate multiple logistic regression analysis. Results: Multivariate non-conditional logistic regression analysis showed that the duration of mechanical ventilation, invasive procedures, gastric tube indwelling, primary disease as chronic obstructive pulmonary disease (COPD), antacid use and APACHEII score for VAP alone Risk factors. CONCLUSIONS: ICU patients with mechanical ventilation have a higher incidence of pneumonia, and can affect the incidence of more factors, the need to take appropriate protective measures.
