摘要
目的 :观察异丙酚与异氟醚复合应用于开颅术中的控制降压效果。方法 :随机抽取 40例开颅手术病人 ,在气管内吸入异氟醚 0 .6～ 1 .0MAc基础上 ,行控制呼吸 ,施行手术。需降压时静脉给予异丙酚 2 .5mg/kg ,再用输液泵维持输入异丙酚至手术不需降压为止 ,同时调整异氟醚为 0 .5～ 0 .8MAc ,监测降压效果及血压恢复情况。结果 :静脉输入异丙酚 2 .5mg/kg后 3.5± 0 .7min ,血压达到理想的控制血压水平 ,MAP为 1 2 .7± 1 .5KPa ,用输液泵调整输入速度为 5～ 5mg/kg/h ,可维持这一水平 ,停用异丙酚后 4.8± 0 .3min ,血压可恢复原水平 ,且无反跳现象。结论 :这种控制降压方法效果确切 。
Objective:To observe the depressing blood pressure effect with propofol and isoflurane during craniotomy anesthesia.Methods:40 cases of craniotomy patients were selected randomly.On the basis of inhaled isoflurane 0.6～1.0 MAC,2.5mg/kg propofol was given intravenously and maintained with pump to regulate dosage from 0.5～0.8 MAC.The depressing effect and Bp recovery were observed.Results:The blood pressure could be obtained ideal level after propofol given 3.5±0.7 min and maintained at this level with pump in 5～8mg/kg.The blood pressure could recover to normal after stopped using propofol 48±0.3min without rebounding.Conclusion:This method could control depressing blood pressure effect and reach reliable results.
