摘要 目的探讨原位肝移植术无肝状态对听觉诱发电位指数(AEPI)的影响。方法15例原位肝移植术患者,设麻醉前、麻醉后、无肝期前、无肝期30min、门静脉开放前5min、新肝3min、新肝30min、新肝60min共8个监测点,观察丙泊酚靶控输注麻醉无肝状态下AEPI的变化。结果麻醉后与麻醉前相比,AEPI明显下降(P〈0.01),无肝期30min和麻醉后相比,有显著下降(P〈0.05),门静脉开放前5min与无肝期30min相比显著下降,新肝期3min与无肝期相比显著下降;新肝30min与新肝期3min相比明显上升,与麻醉后相比差异无统计学意义。新肝开放期间温度(33.2±1.1)℃,最低31.4℃,术前胆红素(219.2±57.8)umol/L,白蛋白(25.6±9.3)g/L。结论丙泊酚麻醉下原位肝移植术中AEPI可调控在25左右,无肝期、低温、高胆红素血症和低蛋白血症均可抑制脑电活动。
