【摘 要】目的：探讨全身麻醉、硬膜外麻醉复合使用影响胸腹部手术患者机体应激反应、血流动力学状态的实际效果。方法：两组患者均因疾病所需接受胸腹部外科手术治疗，其中研究组提供全身麻醉符合硬膜外麻醉，对照组给予单纯气管插管全身麻醉。结果：两组T0时血流动力学及应激反应相关指标检测值对比P>0.05；T1时研究组MAP较T0显著下降(P<0.05)，T2时研究组MAP恢复至T0水平；对照组T1时E水平较T0显著上升(P>0.05)；T2时对照组E水平较T1上升幅度大于研究组(P均<0.05)。结论：利用全身麻醉复合硬膜外麻醉可有效降低胸腹部外科手术患者应激反应强度，有利于保障其疗效及预后。

    Abstract Objective： To investigate the effect of general anesthesia and epidural anesthesia on stress response and hemodynamics in patients undergoing thoracoabdominal surgery. The study group provided general anesthesia in accordance with epidural anesthesia. Results： The relative indexes of hemodynamics and stress response at T0 in the two groups were significantly lower than those in the T0 group (P > 0.05). The MAP of the study group returned to T0 level when the T0 level was lower than that of the T0 group (P < 0.05 and T _ 2.Results： Compared with the T0 group ......
