目的：旨在观察全麻复合硬膜外阻滞对肺癌手术病人循环功能的影响。方法：60例病人随机等分为两组。实验组用异氟醚吸入全农复合胸段硬膜外阻滞；对照组为常规异氟醚麻醉。结果：实验组，麻醉前45min，血压显著下降（P＜0．01），以后逐渐恢复正常；对照组，麻醉后45min，血压显著下降，心年增快。结论：全麻复合硬膜外阻滞可保护肺癌手术病人对创伤的应激能力，减少吸入麻醉药和肌松弛药用量使麻醉中后期循环状态稳定，水后镇痛较好，减少肺部并发症。
Objective: To observe the effect of general anesthesia combined with epidural anesthesia on the circulatory function of lung cancer patients. Methods: 60 patients were randomly divided into two groups. In experimental group, isoflurane was used to inhale epidural thoracic epidural block, and control group was routine isoflurane anesthesia. Results: In the experimental group, blood pressure decreased significantly (P<0.01) 45 minutes before anesthesia, and gradually returned to normal afterwards. In the control group, blood pressure decreased significantly and the heart rate increased rapidly in 45 minutes after anesthesia. Conclusion: General anesthesia combined with epidural anesthesia can protect lung cancer patients from traumatic stress and reduce the use of inhaled anesthetics and muscle relaxants to stabilize the circulatory state in the middle and later stages of anesthesia. The analgesia after water is better and the lungs are reduced. complication.
