摘要 目的总结动脉转位术(ASO)围手术期监护的经验,为提高其疗效提供借鉴。方法回顾性分析2000年1月至2009年6月广东省人民医院收治的135例完全型大动脉转位(TGA)患者行ASO的临床资料,男110例,女25例;手术时日龄1~160 d(27.24±26.49 d),体重2.4~5.0 kg(3.52±0.66 kg)。室间隔完整61例,室间隔缺损74例。术前动态监测血乳酸水平,纠正心功能不全,对98例(72.59%)明显低氧血症患者给予持续静脉注射前列腺素E1[PGE1,2~200 ng/(kg.min)]。手术在低温体外循环下施行,同期矫治合并畸形。术后严密监测凝血指标、左心功能,以间歇指令通气+容量保证通气(SIMV+VG)模式进行呼吸支持。22例术后应用PGE1[4~20 ng/(kg.min)]。结果全组体外循环时间36~423 min(189.20±59.94 min),主动脉阻断时间0~219 min(120.07±31.09 min),118例术后即时血氧饱和度95%~100%。术后机械通气时间24~792 h(168.24±154.80 h),总住院时间1~89 d(30.31±17.21 d)。生存108例,死亡27例(20.00%),主要死亡原因为低心排血量综合征。2001~2003年病死率为50.00%,2004~2006年为36.36%,2007~2009年后为8.43%,明显下降(χ2=18.323,P〈0.001)。术后并发症:感染30例(22.22%),肺不张35例(25.93%);心电图检查示:ST-T改变50例(37.04%),心律失常44例(32.59%);超声心动图提示:吻合口狭窄36例(26.67%),肺动脉狭窄33例(24.44%)。结论 ASO应用于TGA手术效果良好,除手术、麻醉操作外,术前维持内环境稳定、控制血乳酸水平,术后注意呼吸管理、维护左心功能是成功的关键。
