自73年～76年无选择地使用针麻拔牙术共1048例次

现整理如下: 方法全部病例由本科6名医务人员施行麻醉及手术

对多数患者只作简单解释

术前、术中均不给任何药物。按欲拔牙部位选好穴位后消毒进针

手捻者频率150～200次/分

一般要求有“得气”感。电针(应用G 6805或北京626-7A针麻仪)者

不管得气否

导联电极

一般不分正负。如电极导线有标志者

以正极置近手术穴位之毫针上。如为4个穴

048 cases on tooth extractions under acupuncture anesthesia performed in our department from Mar. 1973 to Feb. 1976. Almost all the cases were unselected

except those indicated for tooth ex- tractions with "Instantaneous Method". Details in relation to the apparatus Type G-6805 or Type 626-7A (Beijing) were as follows: Wave form: continuous. Frequency: 150-200 times/min. by twisting with hand; 360 times/min. by electroacupuncture. Current: 7 mA usually. If the wire has signs

the positive pole was connected with the needle which was in the point and near the operated field. In the majority of cases two points were employed. The points Renkuang

Bichungou

Yaoji and Yaojishang were in the maxilla; the points Chenghai and Xiachicao in the mandible

and Hegu (L1-4) was the only point of extremity. Generally

the points were selected according to the locations of teeth. Only brief explanation was given to the cases. No analgesics were given to any of the patients before and during operations. The evaluation of the anesthesia effects was made in four grades in accordance with the criteria made by the Chinese Acupuncture Anesthesia Committee in 1972. Patients' age ranged from 6 to 80

about half of them being workers and peasants. Among the 1

048 cases

1

007 cases with 1

211 teeth were extracted und er electroacupuncture. There was one case in which the time of operation lasted 84 minutes (grade Ⅰ). The statistical treatment of main data was shown as follows: 1) AA effects and location of the teeth: the anterior teeth showed the best effects

the molars the worst but the molars in maxilla were superior to the ones in the mandible(P<0.05). 2) AA had its least effect in the cases in which AA point Xiachicao was used (P<0.01 ). 3) AA effects and patients'age: grades Ⅰ

Ⅱ and Ⅲ in comparison with grade Ⅳ

showed significant difference(P<0.01). 4) The extraction of the impacted teeth and the teeth in the stage of acute imflammations showed the worst effects(P<0.01). 5) The AA induction times

12'-15' proved to be appropriate except grades Ⅱ and Ⅲ (P<0.05 ). 6) The duration of operation averaged about 2 minutes but showed no significant difference between each two groups(P>0.05). 7) Using or not using the point-Hegu showed the same effect in our series of cases(P<0.01). The points

Renkuang and Chenghai were the first choice points for ex- traction of the twelve anterior teeth and they were the most important adjunct points for the other main points recommended by the authors. Our viewpoint is that beween the points and the trunk of the nerves there exists a close relation

or even the two things may be of the same entity. Complications occurred in 21 cases(1.9%). AA effects in grades Ⅰ and Ⅱ were 78.36%

grades Ⅲ and Ⅳ 21.64%. In our opinion AA is superior to local anesthesia in several aspects

particularly

its frequency being stable

easy to control and more lasting etc. all of which are the advantages of the AA apparatus.
