摘要
目的:观察异丙酚芬太尼全静脉麻醉的临床应用效果。方法:14例择期在气管插管全身麻醉下行腹部手术的患者,接受芬太尼总量8μg/kg静脉注射、异丙酚“目标控制性输注法”使脑电双频谱指数降至55~70。实验中分别观察麻醉诱导前(基础值)、气管插管前即刻、气管插管后2min、切皮前、手术操作期5个时相的麻醉效果,并观察平均动脉压(MAP)、心率(HR)、氧饱和度的改变。采用近红外线光谱仪监测脑氧合血红蛋白(HbO2)、还原血红蛋白(Hb)、全血红蛋白(THb)变化。结果:异丙酚芬太尼全静脉麻醉期间MAP维持稍偏低但平稳状态,HR改变不大,HbO2、Hb及THb均有所下降。手术开始后,MAP和HR均呈一定程度升高。结论:异丙酚芬太尼全静脉麻醉时,手术应激反应仍存在,对脑氧合功能影响不大,脑血流有所降低,对血流动力学及脑氧合脑血流动力学均无明显不利效应。
Objective:To observe clinical effect of total intravenous anesthesia(TIVA) with propofol and fentanyl.Methods:In fourteen patients undergoing elective abdominal surgical operation with general anesthesia,the bispectral index(BIS) was decreased to 55 70 with the intravenous injection of fentanyl(a total dosage of 8 μg/kg) and infusion of propofol(target controlled infusion).The changes in anesthetic results,mean arterial pressure(MAP),heart rate(HR),cerebral oxyhemoglobin(HbO 2),hemoglobin(Hb) and total Hb(with a near infrared spectoscope) were observed respectively during the following periods:before anesthesia,before endotracheal intubation,two minutes after intubation,before skin incision and during operation.Results:During TIVA with propofol and fentanyl,reduced MAP with its well maintaining,little change of HR,and a little decreased cerebral HbO 2,Hb and total Hb were shown.But the MAP and HR was increased after initiation of operation.Conclusion:During TIVA with propofol and fentanyl,the surgical stress was still present.Although the cerebral blood flow was a little decreased,the cerebral oxygenation was well protected.It suggests that there was no significant side effects on the hemodynamics and cerebral oxygenation.
