目的 探讨术后谵妄患者的临床特征,并分析谵妄发生的相关因素.方法 收集术后谵妄患者75例的临床资料,抽取同期住院的术后不发生谵妄患者为对照组进行比较.结果 结果分析表明年龄＞60岁(P=0.000)、术中输血(P=0.032)与谵妄发生有关,术后并发症(P=0.113)、睡眠障碍(P=0.086)、应激(P=0.058)与术后谵妄发生无相关性;分析表明术后谵妄的发生与年龄＞60岁(P=0.037)、术中输血(P=0.041)有关.术后非立即苏醒者较立即苏醒者的谵妄潜伏期显著缩短(P<0.05),两者的谵妄量表(delirious state scale,DSS)症状评分差异无显著性(P＞0.05);麻醉后苏醒时间,谵妄潜伏期时间与谵妄的发生无关;谵妄患者的预后良好.结论 年龄大、术中输血是谵妄发生的危险因素; 术后并发症、睡眠障碍、应激促进谵妄的发生.%Objective To explore the clinical characteristics and risk factors of postoperative delirium. Method Seventy-five cases of postoperative delirium patients were selected, while the ones which had no delirium were chosen as control group in the same period. Logistic regression was used to process the data. Results The single factor results indicate that over 60 years old and perioperative blood transfusion are related to the delirium( P = 0. 000, P = 0.032, respectively ); Postoperative complications( sleep, disorder and stress )were not connected with postoperative delirium( P = 0. 113, P = 0. 086, P = 0. 058, respectively ). Logistic regression indicated postoperative delirium was related to age( over 60 years ) and perioperative blood transfusion( P = 0.037, P = 0. 041, respectively ). The delirium incubation period in no immediate revival shortened significantly( P < 0. 05 ),both the DSS symptom score had no significant difference( P > 0. 05 ). Anesthesia waking time and delirium incubation period had no relation with it. The prognosis was good. Conclusion Elderly patient and blood transfusions are the risk factors of delirium. The postoperative complications, sleep disorders, stress promote the delirium.
