老年糖尿病患者全麻术后谵妄筛查的研究

目的：探讨老年糖尿病患者全麻术后谵妄发生率和谵妄筛查量表的筛查效度。方法以DSM- IV诊断作为金标准，调查140例老年糖尿病患者术后谵妄发生率，评价重症监护谵妄筛查量表（ICDSC）的筛查效果。结果老年糖尿病患者全麻术后谵妄发生率为23.8%；ICDSC筛查敏感度0.935，特异度0.889，阳性预测值0.725，阴性预测值0.978，一致性Kappa系数为0.750。结论老年糖尿病患者全麻术后谵妄应引起高度关注，可使用有效筛查工具ICDSC进行常规筛查，提前预防和干预，减少术后并发症，降低病死率。

Screening of postoperative delirium in elderly diabetic patients after general anesthesia

Objective To investigate the incidence of postoperative delirium in elderly diabetic patients after general anesthesia. Methods The incidence of postoperative delirium in 140 elderly diabetic patients after general anesthesia was screened with Intensive Care Delirium Screening Scale （ICDSC）. With DSM- IV as the gold standard for diagnosis of delirium, the validity of ICDSC was evaluated. Results The incidence of delirium was 23.8%in 140 postoperative elderly patients with dia-betes. The sensitivity, specificity, positive predictive value and negative predictive value of ICDSC in diagnosis of delirium were 0.935, 0.889, 0.725 and 0.978, respectively; and the kappa consistency coefficient was 0.750. Conclusion The incidence of postoperative delirium in elderly patients with diabetes is relatively high, and ICDSC can be used effectively in screening of deliri-um for postoperative patients.
