摘要 目的:评价丙泊酚和咪唑安定对ICU机械通气患者的镇静效果和安全性,为危重病人镇静用药提供依据。方法:选择在ICU机械通气治疗的患者54例,随机分为两组,每组27例,分别给予负荷量后改为维持量。丙泊酚组先静注丙泊酚1.0mg/kg行镇静诱导,再改用微量注射泵持续静注,咪唑安定组先静注咪唑安定0.05mg/kg镇静诱导,再改用微量注射泵持续静注,两组均根据Ramsay分级标准,通过调整用量控制患者于Ramsay评分Ⅲ-Ⅴ级。分别记录起效时间,维持镇静的剂量及苏醒时间,停药后再入睡和恶心等情况及两组药物对呼吸循环的影响。结果:丙泊酚和咪唑安定均能达到ICU病人所需的镇静效果。丙泊酚组较咪唑安定组苏醒时间快,且苏醒后再入睡和恶心的发生率明显低于咪唑安定。但丙泊酚组镇静期间有心率减慢、低血压的情况。结论:丙泊酚的镇静作用优于咪唑安定,但需长时间镇静、心血管功能较差或不全的患者更宜用咪唑安定。
