我们曾于临床应用术中辨证选穴针麻胃大部切除术提高了针麻效果

在实验中模拟术中辨证选穴针麻狗胃大部切除术其效果也非常满意。本工作进一步探讨术中辨证选穴对胆囊摘除术的针麻作用

意图仍为临床提供针麻选穴资料。在实验中以动物术中行为表现和反应以及心血管活动作指标进行观察。方法实验动物为31只健康狗

雌雄均有

随机分为甲、乙、对照三组。各组均在清醒状态下捆绑于手术台上

待动物安静30～40分钟开始记录各项指标数椐作为针前基础值

然后分别记录针刺诱导30分钟、处理内脏、Thirty-one healthy dogs were randomly divided into 2 experimental groups and a control group. All dogs were bound on operating tables in conscious state. Behavior and reaction of animals were observed after 30 min.

and heart rates

pulse waves of arteria femovalis

pulse volume waves of skin and muscle of lower leg were simultaneously recorded with amplifier RB- 5 and recorder RTG-3004(paper speed 15-25 mm/sec). The values before and 30 min after acupuncture

during processing viscera and sewing up cuts on abdomen were recorded respectively. Feishu、Xinshu、Ganshu、 Pishu、Neiguan and Zusanli of 12 dogs in first experimental group were used. Xinshu、Pishu、Danshu、Jueyinshu、Yanglingquan and Neiguan of 12 dogs in the second experimental group were used. Operations of 7 dogs in control group were performed under local drug anesthesia. Operations of experimental dogs were performed after 30 min acupunc- ture-inducing with acupuncture anesthesia apparatus 57 6D(frequency of continuous wave was 100 Hz at back acupoints

50 Hz at limb acupoints)

and stimulating intensity was regulated depending on the reaction of ani- mals. Results were as follows: Ⅰ. Effect of acupuncture anesthetic: In the first experimental group 75.00% showed excellent anesthetic results(grade Ⅰ)and 25.00% showed good results(grade Ⅱ). In the second experimental group 33.33% showed excellent anesthetic results

41.67% were classified as good results

and 25.00% were poor (grede Ⅲ). All con- trol dogs had better results than grade Ⅲ

The differences among three groups were statistically significant(p<0.01). Ⅱ. Cardiovascular movement: 1. The difference between indexes of cardiovascular movement before and during acupuncture was not obvious. 2. The differences between the values of heart rate、pulse wave of arteria femoralis、pulse volume wave of skin and muscle before acupunc- ture and the values during operation were not statistically significant in dogs that had excellent anesthetic result. 3. Increases of heart rates of dogs with good or poor anesthetic effects were significant (p<0.01). During processing viscera and sewing up cuts on abdomen

their amplitudes of pulse waves of arteria femoralis and pulse volume waves both greatly decreased (p<0.05). Conclusion: 1. The model of cholecystectomy of animals under acupuncture anes- thesia was established in the present experiment. The results show that there is a relationship between the effect of acupuncture anesthesia and the combination of acupoints

and that there is no relationship between the effect of acupuncture anesthesia and psychological factors. 2. Selecting acupoints depending on behevior and reaction during op- eration may elevate analgesic and other effects of acupuncture anestheia. 3. Effects of acupuncture anesthesia of dogs with stable cardiovascular movements during acupuncture show better effects and vice versa.
