摘要 目的:探讨法舒地尔对心脏手术术后认知功能的影响。方法:择期体外循环(cardiac pulmonary bypass,CPB)下心脏瓣膜置换术患者40例,ASA分级Ⅱ~Ⅲ级,NYHA分级Ⅱ~Ⅲ级,随机分为法舒地尔组和对照组,每组20例。法舒地尔组麻醉诱导前缓慢静注法舒地尔30 mg(加入生理盐水100 mL),3次/d,对照组予等容的生理盐水。记录手术时间、主动脉阻断时间、CPB时间、麻醉时间、麻醉药用量、出血量、输血量、输液量、尿量及术后3天VAS评分。分别于CPB开始前(T1)、升主动脉开放(T2)、CPB结束(T3)及术后6 h(T4)时抽取桡动脉和颈静脉球部血样行血气分析,计算动脉-颈内静脉血氧含量差(Da-jvO2),脑氧摄取率(CERO2)。于术前3 d,术后3、7 d应用简易精神状态检查量表(MMSE)评分,记录术后认知功能障碍的发生率。结果:与对照组比较,法舒地尔组T2、T3时颈内静脉球血氧饱和度(SjvO2)升高,Da-jvO2和CERO2降低(P<0.05),术后3、7 d认知功能障碍发生率降低(P<0.05)。结论:法舒地尔通过降低CPB下心脏瓣膜置换术患者脑氧代谢率,可减少心脏瓣膜置换术患者术后认知功能障碍的发生率。
