摘要 目的观察入院早期使用髂筋膜间隙阻滞持续镇痛对老年髋部骨折患者术后早期认知功能的影响。方法选择择期行单侧髋部骨折手术的患者80例,随机分为2组各40例。2组均采用超声引导下髂筋膜间隙阻滞镇痛,A组为术毕至术后48h,B组为入院即刻至术后48h。观察并记录2组术中情况、芬太尼用量、术前匹茨堡睡眠质量指数量表(Pittsburgh Sleep Quality Index,PSQI)评分和术后认知功能障碍(postoperative cognitive dysfunction,POCD),以及入院后即刻(T0)、术前12h(T1)、术后24h(T2)、术后72h(T3)各时间点的视觉模拟评分法(Visual Analogue Scale,VAS)评分、简易智力状态检查量表(Mini-Mental State Examination,MMSE)评分,并检测各时间点血浆白细胞介素6(interleukin-6,IL-6)和中枢神经特异蛋白(S-100β)浓度。结果 B组术中芬太尼用量较A组少,术前PSQI评分较A组低,POCD发生率较A组少,住院时间较A组短,差异均有统计学意义(P<0.05);2组VAS评分呈降低趋势,2组MMSE评分呈升高趋势,2组IL-6和S-100β浓度呈先升高(T1、T2)后降低(T3)趋势,B组VAS评分、IL-6和S-100β浓度降低幅度较A组更明显,而MMSE评分较A组更高,其组间、时点间、组间·时点间交互作用差异均有统计学意义(P<0.05)。结论术前髂筋膜间隙阻滞持续镇痛可以提供完善的围术期镇痛效果,改善睡眠,减少术中阿片类药物的用量,降低患者免疫炎性反应,从而降低患者早期POCD的发生。
