针药复合麻醉颅后窝手术病人血浆儿茶酚胺的变化

目的：观察针药复合麻醉对颅脑手术病人交感－肾上腺髓质系统的影响。方法：30例颅后窝手术病人分为全麻组、针麻组和针药复合麻醉（GAE）组，测定围手术期外周静脉血去甲肾上腺素和肾上腺素的浓度。结果：针麻组儿茶酚胺水平从手术开始至术后3h均显著高于全麻组和GAE组，术后第1－4天3组间无明显差异。全麻组和GAE组术中儿茶酚胺水平无明显变化，但术后明显升高。结论：从应激角度进行评价，与全麻比较，针麻用于颅后窝手术术中儿茶酚胺反应显著，并无突出优点。而GAE可明显抑制颅后窝手术病人术中儿茶酚胺反应。

Changes of Plasma Catecholamines in Patients undergoing Posterior Cranial Fossa Surgeries Under Acupuncture Anesthesia Combined with Anesthetics

Purpose To investigate the effect of electroacupuncture combined with anesthetics on the sympathetic adrenomedullar system in patients undergoing posterior cranial fossa surgeries.Methods Thirty patients were divided into the general anesthesia(GA) group,electroacupuncture(EA) group,and general anesthesia plus electroacupuncture (GA EA) group.Peripheral blood samples were taken at certain time points before and after the operation,and the concentrations of plasma noradrenaline and adrenaline were determined.Results The catecholamine values in the EA group were markedly higher than those in the GA and GA EA group at the beginning of and 3 hours after the operation.There were no significant differences among the three groups in the first 4 days after the operation.Also no significant changes in catecholamine levels were found between the GA and GA EA groups during the operation,but they were increased significantly after the operation.Conclusion:In the light of stress,no superiority is exhibited by using EA in posterior cranial fossa surgeries compared with GA.However,GA EA has a marked suppressive effect on catecholamine reactions in the patients undergoing posterior cranial fossa surgeries.
