摘　　要：目的探讨老年患者术后发生谵妄的影响因素。方法统计我院169例老年手术患者的年龄、性别以及低氧血症、术后疼痛、睡眠时间减少等的发生情况,对资料进行2χ检验、单因素分析及多因素Logistic回归分析,判定老年患者术后发生谵妄的危险因素。结果169例老年患者术后发生谵妄20例,发生率为11.8%。≥70岁的高龄患者、术中与术后发生低氧血症者、术后疼痛与睡眠时间减少与谵妄发生有关(P<0.01)。高龄患者、术中与术后发生低氧血症者、术后疼痛是谵妄发生的重要影响因素。结论应给予高龄患者特别注意,围术期预防低氧血症,良好的术后镇痛及睡眠对预防术后谵妄有积极意义。Objective To investigate the risk factors of postoperative delirium in elderly patients. Methods For 169 cases of elderly postoperative patients in our hospital, the clinical parameters including age, sex, hypoxemia, postoperative pain, sleeping decrease were investigated as predictive risk factors, the data was dealt with X^2 test or single factor analysis or multivariate Logistic regression analysis. Results Postoperative delirium occurred in 20 cases （ 11.8% ） of 169 elderly patients. Univariate analysis demonstrated that many factors were significantly correlated with the postoperative delirium in elderly patients, such as advanced age （ ≥70）, hypoxemia, postoperative pain and sleeping decrease （ P 〈 0. 01 ）. The multivariate Logistic regression analysis showed that advanced age （≥70） , hypoxemia, postoperative pain were the impotent for onset of delirium. Conclusion Prevention of peri - operative hypoxemia, postoperative analgesia and improvement of sleeping are of active significance for control postoperative delirium.
