【摘要】：目的观察和比较右美托咪定和七氟醚对冠心病非心脏手术患者围术期心肌保护的效应。方法选择择期合并冠心病的腔镜下胸腹部手术患者135例,男90例,女45例,年龄45~82岁,ASAⅡ或Ⅲ级。采用随机数字表法将患者分为三组:对照组(C组),右美托咪定组(D组)和七氟醚组(S组),每组45例。采用依托咪酯0.2mg/kg、丙泊酚0.5mg/kg、顺苯磺酸阿曲库铵0.2~0.3mg/kg和芬太尼5.0~6.0μg/kg进行麻醉诱导和维持,D组诱导前10min开始至手术结束持续泵注右美托咪定。C组给予等容量生理盐水。S组从麻醉诱导后开始持续吸入七氟醚至手术结束前30min停用。记录术中和术后72h内心肌缺血的发生情况。结果术中C组心肌缺血的发生率[12例(26.7%)]明显高于D组[3例(6.7%)]和S组[4例(8.9%)](P0.05);术后72h内C组、D组和S组心肌缺血的发生率分别为6例(13.3%)、4例(8.9%)和4例(8.9%),差异无统计学意义。结论右美托咪定和七氟醚均能通过改善心肌血氧供需平衡,降低冠心病非心脏手术患者心肌缺血的发生率。
