Abstract： 目的初步评价体外循环含钾温血持续灌注心肌保护方法的临床价值.方法对31例先天性心脏病患者(温血组)实施室间隔缺损修补术,采用体外循环含钾温血持续灌注的心肌保护方法.30例先天性心脏病患者(冷血组)实施室间隔缺损修补术,采用体外循环冷血间歇灌注心肌保护.观察两组心脏除颤率、开放主动脉后血钾、术后呼吸机辅助时间及心肌正性肌力药物使用情况.结果温血组与冷血组比较,开放主动脉后心脏除颤率比较差异有显著性(3.2%与26.7%,P＜0.01);心肌正性肌力药物使用时间差异亦有显著性(P＜0.01);术后心功能恢复快,无术后高血钾、低心排血量、严重心律失常等严重并发症.结论体外循环含钾温血持续灌注心肌保护方法可明显减轻心肌缺血与再灌注损伤,先天性心脏病手术中温血持续灌注的心肌保护效果优越,值得推广应用.
