非心脏手术患者术后早期谵妄与预后的关系

Relationship between early postoperative delirium and prognosis in patients undergoing non-cardiac surgery

目的 探讨非心脏手术患者术后早期谵妄（EPD）与预后的关系.方法 采用前瞻性队列研究设计,选择2009年6月至12月在本院全麻下行非心脏手术患者698例,收集影响患者预后的相关因素,根据CAM-ICU诊断标准判断是否发生EPD,分为EPD组和非EPD组（NEPD组）,以术后住院时间作为主要预后指标,将EPD和对术后住院时间有影响的混杂因素纳入Cox比例风险回归模型进行分析,筛选影响患者预后的危险因素.结果 EPD组197例,NEPD组501例,EPD发生率28.2%,EPD组患者术后住院时间长于NEPD组,EPD是影响患者预后的独立危险因素之一.结论 EPD是影响非心脏手术患者预后的独立危因素之一.

Objective To determine the relationship between early postoperative delirium （EPD） and prognosis in patients undergoing non-cardiac surgery. Methods This was a prospective cohort study consisted of 698 patients admitted to postanesthesia care unit, undergoing non-cardiac surgery under general anesthesia, between June and December 2009. The risk factors affecting prognosis were collected. All the patients were assessed for the development of delirium by experienced research staff using Confusion Assessment Method for Intensive Care Unit. The patients were divided into 2 groups according to the occurrence of EPD： EPD group and no EPD （NEPD） group. The postoperative hospital length of stay was made as a major prognostic indicator. Cox proportional hazard regression model was used to analyze the risk factors affecting prognosis. Results Of the 698 patients, 197 （28.2%） developed EPD. The postoperative hospital length of stay was prolonged in group EPD compared with group NEPD. The Cox proportional hazard regression model analysis indicated that EPD was an independent risk factor affecting prognosis. Conclusion EPD is an independent risk factor affecting prognosis in patients undergoing non-cardiac surgery.
