Abstract:

目的探讨血氨对肝硬化大鼠丙泊酚麻醉后苏醒时间的影响。方法健康雄性SD大鼠20只,体重180~220g,鼠龄10~12周,随机分为正常对照组(10只)和肝硬化组(10只)。肝硬化组采用四因素法制备大鼠肝硬化模型,模型制备成功后,尾静脉注射丙泊酚12mg?kg-1?(2ED?50?),记录两组大鼠的麻醉作用时间,以大鼠前爪翻正反射消失和翻正反射恢复作为判断丙泊酚麻醉起效和麻醉苏醒的指标。下腔静脉取血2mL,检测血氨的含量。结果与对照组比较,肝硬化组大鼠翻正反射恢复明显延长(?P?<0.05),血氨含量明显升高(?P?<0.05)。结论肝硬化大鼠丙泊酚麻醉后苏醒时间延长可能与血氨浓度增高有关。
