目的 了解老年髋关节置换术后患者亚谵妄综合征的发生现状。方法 选取2021年5月—12月郑州市某三级甲等医院骨科病区收治的102例髋关节置换术后患者为研究对象，调查其年龄调整的合并症指数及中文版3分钟谵妄诊断量表评分结果，并记录患者骨折部位、术前禁食禁水时间、术前卧床时间、手术时间等。结果术后有75例患者出现亚谵妄综合征。与非亚谵妄组相比，亚谵妄组患者女性居多，年龄调整的合并症指数高，术前卧床、禁食、禁水时间长（均P<0.05）。结论 老年髋关节置换术后患者亚谵妄综合征的发生率较高，应重点关注女性患者、年龄调整的合并症指数高且术前卧床、术前禁食、禁水时间长的患者。

Objective To investigate the current status of subsyndromal delirium in elderly patients after hip arthroplasty. Methods One hundred and two patients with hip arthroplasty who were admitted to the orthopaedic ward of a tertiary first-class hospital in Zhengzhou City were selected from May to December 2021. The Age-Adjusted Charlson Comorbidity Index（ACCI） and the Chinese version of the 3-minute Diagnostic Interview for CAM were investigated. Meanwhile，the fracture site，preoperative fasting and water prohibition time，preoperative bed rest time，and the duration of surgery were recorded. Results Seventy-five patients developed subsyndromal delirium after operation. Compared with the non-subdelirium group，the subdelirium group had a greater proportion of women，higher ACCI，and longer preoperative bed rest，fasting，and water deprivation（all P<0.05）. Conclusion The incidence of subsyndromal delirium in elderly patients after hip arthroplasty is high，and medical staffs should pay attention to the female patients，and patients with high ACCI，preoperative bed rest，preoperative fasting，and prolonged water deprivation.
