普鲁卡因——芬太尼静脉麻醉下体温及温度调节反应的研究

THE STUDY OF TEMPERATURE AND THERMO——REGULATION DURING INTROVENOUS ANESTHESIA OF PROCAINE——FENTANYL.

全麻下机体的体温调节反应通常被抑制,但由于全麻中肌肉松驰药的应用,机体唯一的体温调节反应只可能是外周血管收缩和非寒颤性产热。为估计麻醉对体温调节反应的影响,作者应用皮肤温差级数(前臂——指尖温差)及食道温度监测方法对40例ASA分级Ⅰ——Ⅱ级行胃癌根治术的病人进行了观察。结果示全麻病人术中存在着活跃的温度调节反应,其主要方式为外周血管收缩和非寒颤性产热。

Although Suppression of thermoregulatory mechanisms by anesthetics is generally assumed, the extent to which thermoregulation is active during anesthesia is not known. The only thermoregulatory responses available to the anesthetized are vasoconstriction and non-shivering thermogenesis. To test anesthetic effects on thermoregulation, the authors measured skin-surface temperature gradients (forearm temperature—fingertip temperature)and esophageal temperature on 40 patients,ASA physical Status Ⅰ——Ⅱ, undergoing. radial operation of gastric Cancer. The study indicate that active thermoregulation occurs during introvenous anesthesia of procaine-fentanyl. The main modelsof thermoregulation are vasoconstriction and non—shivering thermogenesis.
