Trachea surface anesthesia or and epidural block reduces isoflurane requirements in general anesthesia 和硬膜外阻滞降低异氟醚吸入全麻用药量
2.
Methods : we selected 23 cases of liver disorder at advanced stage , the liver transplantation was performed under epidural blockade ( 0 . 75 % ropivacaine ) combining with general anesthesia ( lower concentration isoflurane ) 方法：选择终末期肝病患者23例，在0 . 75 %罗哌卡因持续硬膜外阻滞复合吸入低浓度异氟醚全麻下行肝脏移植手术，术中严密监测各项生理参数及生化指标。
