摘要 目的初步探讨乌司他丁在不停跳心内直视手术中对心肌的保护作用。方法选择60例先天性房间隔缺损或室间隔缺损患者,随机分为对照组(C组)与乌司他丁组(U组),每组各30例。手术均在浅低温体外循环心脏跳动下完成。U组按乌司他丁1万U/kg使用,于麻醉后体外循环前加入1/2干预充液中,余1/2在开放上下腔静脉后加入氧和器中,C组不接受乌司他丁。检测术前、及术后24h心肌酶谱AST、LDH、CK、HDBH的变化以及术后24h心包引流量。结果乌司他丁组术后24h AST、LDH、CK、HDBH的活性与对照组相比有明显差异,使用乌司他丁组的活性要低于对照组的心肌酶谱活性,同时乌司他丁组的患者术后心包引流量要明显低于对照组。结论乌司他丁在不停跳心脏手术体外循环期间可抑制AST、LDH、CK的活性,从而减轻CPB期间心肌缺血/再灌注损伤,起到良好的心肌保护作用。
