摘要 目的 探讨瑞芬太尼分别伍用依托咪酯和异丙酚在真空旋切乳腺肿物静脉麻醉中对呼吸循环的影响及适宜剂量.方法 120例ASAⅠ-Ⅱ级患者,均为女性,随机分为6组(n=20).E1组:依托咪酯0.3 mg/kg,瑞芬太尼1 μg/kg;E2组依托咪酯0.3 mg/kg,瑞芬太尼1.5 μg/kg;E3组:依托咪酯0.3 mg/kg,瑞芬太尼2 μg/kg;B1组:丙泊酚2 mg/kg,瑞芬太尼1 μg/kg;B2组:丙泊酚2 mg/kg;瑞芬太尼1.5 μg/kg;B3组:丙泊酚2 mg/kg,瑞芬太尼2 μg/kg.记录麻醉前、意识消失后、手术开始时的平均动脉压(MAP)、心率(HR)、脉搏血氧饱和度(SpO2),观察苏醒时间、呼吸抑制及术中知晓情况.结果 意识消失后:E组MAP、SpO2有不同程度下降,但差异无统计学意义(P﹥0.05),HR在瑞芬太尼2 μg时下降明显,与术前相比差异有统计学意义(P<0.05).B组MAP、HR、SpO2在麻醉后均有下降,在瑞芬太尼2 μg组下降明显,与术前相比差异有统计学意义(P<0.05).组间比较:MAP在意识消失后两组相比差异有统计学意义(P<0.01),HR差异无统计学意义(P﹥0.05).呼吸抑制E组和B组差异有统计学意义(P<0.05),术毕清醒时间,E组和B组指标差异无统计学意义.结论 依托咪酯复合瑞芬太尼静脉诱导对呼吸循环影响更小,瑞芬太尼1.5 μg/kg,依托咪酯0.3 mg/kg麻醉更平稳.
