摘要
目的 :观察胸部硬膜外麻醉对老年人全麻气管内插管时心血管反应的抑制作用。方法 :利用胸部硬膜外麻醉对 4 0例老年择期全麻手术病人进行分组对比研究 ,观察全麻气管内插管时血流动力学、心肌耗氧及应激性激素 (PRA、AⅡ )的变化。结果 :实验组气管内插管时血流动力学和心肌耗氧指标及RN、AⅡ显著低于对照组并在围插管期保持平稳。结论 :胸部硬膜外麻醉可抑制老年手术患者全麻气管内插管时血浆儿茶酚胺分泌 ,保持插管期间血流动力学的稳定。
Objective:To investigate the inhibition of thoracic epidural anesthesia on cardiovascular responses during tracheal intubation of general anesthesia in old patients.Method:40 old patients were schedulde to have general anesthesia and divided at random into experimental group and control group(n=20).The data change of hemodynamics and myocardial oxygen consumption were observed blood Samples were obtained to detect plasma renin(PRE)and angiotensinⅡ(AⅡ).Result:The data of PRE,AⅡ,hemodynamics and myocardial oxygenic consumption in control group were significantly higher than those of experimental group.Concolusion:During tracheal intubation in old patients thoracic epidural anesthesia can effectively inhibit the secretion of plasma catecholamine,block the cxciting cardiac sympathetics and maitain hemodynamics stable.
