Abstract

目的 对开塞露肛注和蓖麻油口服2种促排便措施对急性心肌梗死(AMI)早期患者排便时心脏功能状态的影响进行比较,为临床护理提供依据.方法 将需采取促排便措施的AMI早期患者随机分为开塞露组和蓖麻油组,开塞露组给予开塞露20~40 ml肛注,蓖麻油组给予蓖麻油10~30 ml口服.观察比较患者在平静、促排便前、促排便后、便中前期、便中后期、便后整理、便后5 min、便后30 min 8个时段中心率、血压、心肌耗氧量等指标的变化.结果 开塞露组与蓖麻油组在促排便后开塞露组的心率和心肌耗氧量显著高于蓖麻油组,且有显著性差异(P<0.05),其他时段无显著性差异.结论 开塞露肛注者与蓖麻油口服者在排便过程中各时段心脏自律性和心肌缺血情况的变化基本相同.但在开塞露肛注后等待排便期间,患者的心肌耗氧量较蓖麻油口服者增加明显,不宜过多延长开塞露肛注后等待排便的时间。
