坐位颅脑手术的麻醉处理

目的　研究如何减轻坐位颅脑手术病人的生理变化。方法　 2 0例病人均采用体位改变前扩容、半清醒插管、体位改变后进行控制呼吸等方法。监测心率、血压、血氧饱和度及尿量的变化。结果　患者在体位改变及麻醉前后心率、血压、血氧饱和度等生理指标改变不明显。结论　采用半清醒插管、体位改变前扩容等措施可减少体位改变对机体的不良影响。

The Anesthesia of Cerebral Operation in Sitting Position

Objective To Study how to reduce the physiologic change during posterior fossa operation in sitting position. Methods Twenty patients were administered balanced salt solution 20mg/(kg·h) and gelofusine 20mg/(kg·h) before posture change, the laryngeal pharynx and trachea were given superficial anesthesia; Diazepam 0.2mg/kg was infused intravenously , after posture change the patients were given controlled respiration. The heart rate, blood pressure, SPO-2 and urine volume were monitored intraoperatively. Results No significant changes were found in HR, MAP, SPO-2 and other physiological indices either between the posture shifts or before and after the administered anesthesia. Conclusion The combination of increasing volume before posture change , intubating in semiconsciousness and control respiration after posture change may reduce the physiological effect and improve the safety of anesthesia during posterior fossa operation in sitting position.
