摘要： 目的 评估心脏外科重症监护病房（CSICU）患者术后谵妄的发生率,分析其危险因素及各危险因素预测术后谵妄发生的效能。方法 采用横断面调查研究法,选取2019年1—5月于某三级甲等综合医院CSICU住院的心脏手术后患者为研究对象。谵妄评估采用ICU患者意识模糊评估法,采用一般资料调查问卷、急性生理和慢性健康评分（Acute Physiology and Chronic Health Evaluation,APACHEⅡ）、中文版重症监护疼痛观察工具、匹兹堡睡眠质量指数量表和ICU环境压力源量表收集资料。采用单因素分析及多因素Logistic回归分析患者术后谵妄的危险因素,利用受试者工作特征曲线（ROC曲线）描述各危险因素的曲线下面积及最佳临界值。结果 （1）共纳入316例患者,发生谵妄81例（25.6%）, Logistic回归分析结果显示,术后谵妄的独立危险因素包括：APACHEⅡ评分（OR=1.257,95%CI为1.018~1.553）,停循环时间>15 min（OR=6.943,95%CI为1.288~37.429）,术后疼痛平均得分（OR=2.918,95%CI为1.749~4.867）,睡眠质量得分（OR=1.147,95%CI为1.038~1.267）,ICU环境压力源得分（OR=1.161,95%CI为1.110~1.214）。（2）ROC曲线结果显示：APACHEⅡ评分、停循环时间>15 min、术后疼痛平均得分、睡眠质量得分、ICU环境压力源得分的曲线下面积分别为0.745、0.617、0.758、0.837、0.910,APACHEⅡ评分、术后疼痛平均得分、睡眠质量得分、ICU环境压力源得分的最佳截断值分别为9分、3分、14分、72分。结论 CSICU患者术后谵妄的发病率处于一个较高水平,APACHEⅡ评分>9分、停循环时间>15 min、术后疼痛平均得分>3分、睡眠质量得分>14分、ICU环境压力源得分>72分的患者更容易发生术后谵妄。本研究为完善CSICU患者术后谵妄的管理提供参考依据。

Abstract: Objective To evaluate the incidence of postoperative delirium in patients in cardiac surgery intensive care unit (CSICU), and to analyze the risk factors and the efficiency of each risk factor in predicting postoperative delirium. Methods In this cross-section survey, patients hospitalized in CSICU after cardiac surgery of one tertiary grade A hospital from January to May 2019 were selected as research objects. Confusion Assessment Methodfor the Intensive Care Unit, general information questionnaire, Acute Physiology and Chronic Health Evaluation (APACHEⅡ), Critical-care Pain Observation Tool, Pittsburgh sleep quality index and intensive care unit environmental stressor scale were used to collect the data. Risk factors of postoperative delirium in CSICU patients were analyzed by using single factor analysis and multivariate logistic regression. ROC curve was used to describe the predictive effectiveness of the risk factors and the best threshold. Results Of the 316 patients included, 81 cases of delirium were found, with an incidence of 25.6%. Logistic regression showed that APACHEⅡscore(OR=1.257,95%CI=1.018~1.553), circulatory arrest time more than 15 minutes (OR=6.943, 95%CI=1.288~37.429), average postoperative pain score (OR=2.918, 95%CI=1.749~4.867), sleep quality score (OR=1.147,95%CI=1.038~1.267),and ICU environment pressure source score(OR=1.161,95%CI=1.110~1.214) were independent risk factors of postoperative delirium. ROC curve results showed that the area under the curve of APACHEⅡ,circulatory arrest time longer than 15 minutes, mean score of postoperative pain, sleep quality score and ICU environmental pressure source score were 0.745, 0.617, 0.758, 0.837 and 0.910 respectively, and their optimal cut-off value was 9, 3, 14 and 72 respectively. Conclusion The incidence of postoperative delirium CSICU patients is high. Postoperative delirium is more likely to occur in patients with APACHEⅡscore>9, circulatory arrest time longer than 15min, mean score of postoperative pain>3, score of sleep quality>14,and score of ICU environment pressure source>72 are risk factors of postoperative delirium. This study provides reference for improving the management of postoperative delirium in CSICU patients.
