摘要 目的:评价血必净对老年腹部手术患者术后认知功能障碍(postoperative cognitive dysfunction,POCD)的影响。方法:择期行腹部外科手术的高龄患者120例,年龄≥60岁,ASAⅠ~Ⅱ级、随机分为两组,血必净组和对照组,每组60例;血必净组男33例,女27例,年龄60~83岁,在术前1d及手术切皮前(8mL/kg),术后第1、2、3天4mL/kg静脉滴注,每天2次。对照组男31例,女29例,年龄60~85岁,使用等量生理盐水;在术前1d术后4d及3个月进行神经心理学测试、一个或多个认知功能缺陷被确定为认知功能障碍。结果:术后4d及3个月,对照组有16例患者发生POCD(26.7%)和(28.30%),血必净组有5例发生POCD(8.3%)和(13.3%)较对照组低(P<0.05);与没有发生认知功能障碍的患者比较,术后4d发生POCD患者围术期各时间点血浆稳态氧化氮产物(NOX)浓度明显增强(P<0.05)。结论:老年腹部手术患者围术期应用血必净,能一定程度预防术后认知功能障碍的发生。
