摘　　要：目的:对40例颅内动脉瘤手术的麻醉处理进行回顾。方法:诱导插管后施行丙泊酚和异氟醚静吸复合全麻,术中应用压宁定、尼莫地平或异氟醚施行控制性降压,用Ohmedar麻醉机施行控制呼吸。结果:诱导后HR和MAP有显著性降低,但在正常范围内;维持期MAP略有下降,但MAP平均值仍维持在(13.8±1.50)kPa,其他指标SpO_2、PETCO_2、ECG等均无大变化。结论:颅内动脉瘤夹闭术的麻醉诱导及维持要求平顺稳定,术中需施行控制性降压以避免脑动脉瘤破裂并减少出血。Objective： To retrospect the 40 cases of anaesthesia in intmcranial aneurysm surgery. Method： Propofol and isoflurane inhalation-intravenous anesthesia was applied after intubation, and urapidil, nimodipine or isoflurane-induced controlled hypotension was used during the operation. Breathing was controlled with Ohmedar anesthesia machine. Results： HR and MAP significantly decreased after induction, but it was still in the normal range. MAP decreased slightly in maintenance period, and the average of MAP remained at （ 13.8±1.50 ） kPa. The indicators such as SpO2, P ETCO2 and ECG changed insignificantly. Conclusion： The induction and maintenance of anesthesia requires good stability in intracranial aneurysm surgery. Intraoperative controlled hypotension was needed to avoid cerebral aneurysms rupture and reduce bleeding.
