摘　　要：目的：应用经颅多普勒（ＴＣＤ）研究不同剂量芬太尼和依托咪酯复合诱导气管插管对神经外科病人脑血流动力学的影响。方法：２０例病人随机分成两组（每组１０例）：Ｆ５组，芬太尼５μｇ／ｋｇ；Ｆ１０组，芬太尼１０μｇ／ｋｇ。余诱导用药相同：安定０．１ｍｇ／ｋｇ、依托咪酯０．３ｍｇ／ｋｇ、维库溴铵０．１ｍｇ／ｋｇ。采用ＴＣＤ监测双侧大脑中动脉血流速率（Ｖ－ＭＣＡ），同时监测ＢＰ、ＨＲ、ＰＥＴＣＯ２和ＳｐＯ２。记录麻醉诱导前、插管前和插管后３分钟的变化。结果：与麻醉前比，插管前和插管后３分钟，两组Ｖ－ＭＣＡ均明显降低（Ｐ＜０．０１）；血压在插管前降低（Ｐ＜０．０１），插管后恢复麻醉前水平。但两组间的变化差异无显著意义。结论：芬太尼和依托咪酯复合诱导能抑制插管刺激引起的脑血流量增加和心血管反应，减少脑血流量。Objective: To evaluate the effect of fentanyl-etomidate coinduction on cerebral blood flow velocity in neurosurgical patients. Methods: 20 patients were allocated randomly into two groups (10 each): F5 group, fentanyl 5μg/kg; F10 group, Fentanyl 10μg/kg. Anesthesia was induced with diazepam 0. 1mg/kg, fentanyl 5μg/kg(F5 group ) or 10μg/kg(F10 group), vecuromum 0. 1mg/kg and etomidate 0. 3mg/kg. After endotracheal intubation, the ventilation was performed to maintain PET CO2 of 35-45mmHg. The middle cerebral artery blood flow velocity (V-MCA), mean artery blood pressure (MAP), heart rate(HR), PET CO2 and SpO2 were measured before induction, after intubation and at 3min after intubation. Results: There were no significnt differences in preinduction data(weight, sex, MAP, HR) between two groups. The V-MCA decreased signifieantly (P < 0. 05) after induction and at 3min after intubation in both groups. Conclusion: Co-induction of fentanyl with etomidate could decrease cerebral artery blood flow velocity during intubation.
