硬膜外阻滞下腹腔镜胆囊切除术时酸碱平衡及呼吸功能的变化

Changes of acid-base balance and respiratory punction in patients under epidural anesthesia during laparoscopic cholecystectomy

观察硬膜外阻滞下腹腔镜胆囊切除术(LC)患者血液酸碱平衡及呼吸功能的变化。结果表明,硬膜外阻滞者LC时可出现一过性高碳酸血症和代谢性酸中毒,因患者处于清醒状态,可通过代偿性加强呼吸,在一定程度上排出腹腔内吸收的二氧化碳气体,使气腹后体内酸碱恢复正常,所以,硬膜外阻滞下行LC是安全可行的。

This study observed the changes of acid-base balance and respirary function in patients under epidural anesthesia during laparoscopic cholecystectomy(LC). The results showed that there were temporary hypercarbia and metabolic addosis in patients under epidural anesthesia during LC. But, these patients were conscious, they could eliminate carbon dioxide from abdominal cavity through compensatory increasing of respiratory function and maintained acid-base balance in their body after LC. It is suggested LC under epidural anesthesia was safe and possible.
