老年患者全髋关节置换术后认知功能障碍与围术期炎性反应的相关性

目的 观察老年患者全髋关节置换术后早期术后认知功能障碍(POCD)的发生及其与围术期炎性反应的关系.方法 选择接受择期单侧全髋关节置换术的老年(年龄≥60岁)患者,应用简易精神状态量表(MMsE)对患者的认知功能进行评定,根据是否发生POCD分为POCD组(17例)和非POCD组(20例),检测术前及术后1、6 h外周血白细胞介素(IL)-1β、IL-6、肿瘤坏死因子(TNF)-α和C反应蛋白(CRP)水平.结果 术后1 d的POCD发生率为45.9%.POCD组患者术后IL-1β及IL-6水平均较术前显著升高(P值均＜0.05);非POCD组患者术后仅IL-6水平较术前显著升高(P值均＜0.05),IL-1β水平无明显变化(P值均＞0.05);POCD组术后1 h的IL-1β及术后6 h的IL-6水平显著高于非POCD组(P值均＜0.05).两组患者手术前后TNF-α水平的差异无统计学意义(P值均＞0.05).两组患者术后6 h的CRP水平较术前显著升高(P值均＜0.05),但两组间的差异均无统计学意义(P值均＞0.05).结论 老年患者全髋关节置换术后早期的POCD发生率较高,术后早期的炎性反应可能与POCD的发生有关.

Correlation between postoperative cognitive dysfunction and peri-operative inflammation in elderly patients undergoing total hip-replacement surgery

Objective To observe the incidence of postoperative cognitive dysfunction (POCD) in elderly patients undergoing total hip-replacement and to explore the relationship between POCD and peri-operative inflammation. Methods Thirty-seven elderly patients (all aged more than 60) undergoing selective hip-replacement surgery were enrolled in this study. Neuropsychological testing was performed with mini-mental state examination (MMSE) on the preoperative day and on the 7th postoperative day. The patients were divid...
