摘要 目的通过使用脑电双频谱指数(bispectralindex,BIS)对危重病人麻醉深度进行监测,探讨是否可以减少麻醉药物的用量,减轻对病人循环、呼吸、肝肾功能的抑制,从而减少围手术期危重病人麻醉的风险性,提高手术的安全性。方法 40例择期行全麻手术危重病人,随机分为BIS组和对照组,每组各20例。BIS组通过调整异丙酚用量使患者BIS值保持在40~60,两组丙泊酚的血浆靶浓度设定为2.0μg/kg。记录诱导前、插管后5min、开皮后5min、开皮后1h及手术毕5min所测定的MAP、HR、SpO2、BIS值的变化以及丙泊酚用量。结果两组患者平均动脉压的变化差异明显,两组患者插管后5min血压均较诱导前降低,对照组在插管后5min下降较BIS组明显,BIS组异丙酚使用量要比对照组少。结论在危重病人手术麻醉过程中使用BIS监测麻醉深度,可以减少异丙酚用量,提高病人手术的安全性。
