危重患者谵妄发生的危险因素分析

目的探讨危重患者ICU谵妄发生的危险因素。方法选择2015年1~6月我院ICU收治的年满18周岁,ICU停留时间大于24h的174例患者,采用CAM-ICU每天两次对患者进行评估,并将患者分为谵妄组与非谵妄组。采用单因素和多因素logistic回归对酗酒史等12个因素与谵妄发生之间的关系进行分析。结果 174例患者中谵妄发生率为22例(12.64%)(谵妄组),非谵妄组为152例(87.36%)。Logistic回归分析结果显示:冠心病史(OR 3.932,95%CI 1.225~12.617)、手术(OR 9.691,95%CI 2.103~44.657)、低氧血症(OR 6.595,95%CI 1.377~31.585)、苯二氮?类药(OR 7.620,95%CI 1.713~33.899)是危重患者发生ICU谵妄的危险因素(P0.05或P0.01)。结论冠心病史、手术、低氧血症、苯二氮?类药是危重患者发生ICU谵妄的独立危险因素,应及早行谵妄筛查,积极预防ICU谵妄的发生。

Analysis of risk factors of delirium in critically ill patients

Objective To investigate the risk factors of ICU delirium in critically ill patients. Methods A total of 1 74 critically ill patients in ICU who were older than 18 yrs and stayed in ICU exceeding 24 hs from January 201 5 to June 201 5 were enrolled.Patients were divided into delirium group and non delirium group.Delirium was assessed twice daily with the Confusion Assessment Method for the ICU (CAM-ICU)during the first 7 days.The factors such as history of alcoholism and other 12 factors were analyzed by univariate and multivariate logistic regression analysis to identify those risk factors associated with delirium.Results With 22 cases of delirium in 1 74 patients,the in-cidence of delirium was 12.64% (delirium group).Variables associated with delirium were coronary heart history,operation,tracheal intubation,clinical use of mechanical ventilation,hypoxemia and Benzodiazepine.Multivariate logistic regression analysis showed that coronary heart disease (OR 3.932,95%CI 1.225-12.61 7),surgery(OR 9.691,95%CI 2.103-44.657),hypoxemia(OR 6.595, 95%CI 1.377-31.585),Benzodiazepine use (OR 7.620,95%CI 1.713-33.899)was independent risk factors of delirium in critically ill patients (P < 0.05 or P < 0.01 ).Conclusion Coronary heart disease,surgery,hypoxemia and Benzodiazepine are independent risk factors of ICU delirium in criti-cally ill patients.Early screening and prevention of delirium should be given to reduce the occurrence of delirium for patients in ICU.
