On account of the incompleteness of acupuncture analgesia the application of acupuncture anesthesia was limitted. So the combination of acupuncture with small doses of supplementary drugs has been used recently. In this work the experiments were divided into 4 groups: 1. subtotal gastrectomy was performed under acupuncture combined with Dolantine (Img/kg i.v., atropine 0.3 mg i.m. 0.5% procaine 5ml infiltrated around the gastric arteries);

2. Operation was done under acupuncture alone (10 cases); 3. Operation was performed under acupuncture combined with local infiltration of 0.5% procaine 2-3ml around each gastric arteries (12 cases); 4. Operation was preformed with neither acupuncture nor supplementary medications,

The best anesthetic effect was obtained in group 1., during operation the dogs kept quiet. Both the arterial and the venous pressures were steady. In group 3., the dogs also kept quiet. The blood pressure fluctuated only during the unsuitable infiltration. In group 2. the dogs were not so quiet but the operations were to be able to continue and there were mild blood pressure fluctuations. In the control group 4, subtotal gastrectomy was performed without acupuncture or any other anesthetic medications, the dogs yelped and fought when the abdomen was incised and when the stomach was pulled. The operation was impossible to complete. A marked elevation of arterial blood pressure occurred at the earlier stage of operation, and a marked drop was present in the later stage of operation. The central venous pressure showed elevation through the whole operation.

Considering together the correlating changes of Noradrenaline and DBH activity in blood, We assumed that the elevation of arterial blood pressure was related to the excitation of the peripheral synpathetic nervous system, while the elevation of the venous blood pressure was elicited by the muscle contraction occurred during the pain and visceral fractional reactions.

All the results showed that acupuncture combined with supplementary medications was effective to overcome the incompleteness of the acupuncture analgesia.
