耐电针阈与内脏牵拉反应的关系

<正> 内脏牵拉反应与针麻效果关系很密切,临床针麻往往因为内脏牵拉反应严重而增加术中用药量或改变麻醉方法,因此研究针刺控制内脏牵拉反应是一项重要课题。近年来许多学者研究针刺抑制内脏痛和内脏牵拉反应原理,提供了大量的宝贵资料。1976年我们根据患者接受电针刺激量的大小以观察其对术中内脏牵拉反应的影响,发现耐电量大者术中反应发生率低,耐电量小者术中反应发生率高。后来我们采取诱发的方法提高患者术前耐电针阈,意图控制术中内脏牵拉反应,结果证明确实有效,现总结于下。

RELATIONSHIP BETWEEN VISCERAL TRACTION REACTION AND ELECTRO-ACUPUNCTURE TOLERANCE THRESHOLD

In 130 cases of subtotal gastrectomy under acupuncture anaesthesia, we performed electro-acupuncture induction to elevate electro-acupuncture tolerance threshold, and observed the relationship between it and visceral traction reaction in the course of operation. 1. 50 cases in the control group were not induced to elevate their electro-acupuncture tolerance thresholds (the average value was 3.14±1.23). 80 cases in the experimental group were induced to elevate their electro- acupuncture tolerance thresholds. The difference between the two groups was statistically significant(p<0.01). These results indicated that induc- tion might elevate electro-acupuncture tolerance threshold. 2. The incidence of visceral traction reaction in experimental group greatly declined as compared with that in the control group. X~2 test showed statistical significance(p<0.01). These results indicated that there was a direct relationship between the incidence of visceral traction reaction and the level of electro-acupuncture tolerance threshold, and therefore visceral traction reaction might be inhibited by elevating electro-acupuncture tole- rance threshold.
