50例脑动脉瘤夹闭手术患者麻醉效果临床研究

Clinical Research on Anesthetic Effect of 50 Cases of Cerebral Aneurysm Which Underwent Clipping Surgery

目的研究探讨脑动脉瘤患者行夹闭手术治疗前有效的麻醉方法。方法将到该院就治的50例脑动脉瘤患者随机平均分为两组,A组术前采用咪唑安定麻醉,B组术前采用瑞芬太尼麻醉,两组均于钳夹动脉瘤前加深麻醉,并给予尼卡地平进行控制性降压,观察两组患者麻醉效果。结果 B组患者术后自主呼吸恢复、意识恢复、导管拔除、定向力恢复时间均短于A组(P<0.01)。结论脑动脉瘤夹闭手术麻醉的重点在于保证患者在诱导期及维持期血流动力学平稳,瑞芬太尼较咪唑安定麻醉效果好,其既能保持足够的麻醉深度,又能有效控制患者血压。

Objective To study anesthetic effect of cerebral aneurysm which underwent clipping surgery. Methods Randomly avarage divided 50 cerebral aneurysms which underwent clipping surgery into two groups.At preoperative, A group were given midazolam for anesthesia, B group were given remifentanil for anesthesia,both groups were given deepening anesthesia before clamping the aneurysm, and given nieardipine controlled hypotension,observed anesthetic effect. Results Recovery of spontaneous breathing,recovery of consciousness ,recovery of disorientation time of B group were shorter than A group（P〈0.01）. Conclusion The key of cerebral aneurysm undewent clipping surgery is to ensure hemodynamies and vital signs of patients stable in induction phase and maintenance phase, anesthetic effect of remifentanil is better than midazolam, it can maintain depth of anesthesia in adequate,as well as effectively control blood pressure.
