Our clinical experience in using point Futu for acupuncture anesthesia in 1000 cases of thyroid operations was summarized. Anesthetic effects were; Grade I 572 (57.2%), grade II 351 (35.1%) and grade III 77 cases (7.7%).

1. The indications of acupuncture anesthesia were investigated in view of its effect according to various diseases, operations and operative durations. The investigation disclosed that the grade I and II effectiveness reached more than 90% in all 756 cases of adenoma and 196 cases of cyst adenoma of the thyroid gland. Anesthetic effectiveness in 738 cases with operative duration less than two hours was better than that in 262 cases with the duration over two hours. The grade I and II effectiveness rates were respectively 94.6% and 85-9%. The anaesthesia effectiveness in various operations in subtotal thyroidectomy showed grade I and II 93.7%, higher than that in total thyroidectomy, 86,2%.

2. Influence of different manipulative methods upon acupuncture anaesthesia effect. Grade I and II effectiveness rates of three groups (points Futu and Neiting 68 cases, points Futu, Hegu and Neiguan 70 cases and Futu plus needling wrist and ankle 50 cases) were respectively 92.6%, 92.9% and 90.9%, being not distinctly improved as compared with 92.7%, a rate when only point Futu was adopted.

In different complementary medication groups the grade I and II acupuncture anesthetic effect might be encountered over 90% of cases using Petidine 1.5 mg/kg and using the same drug 1 .Omg/kg plus Droperidol 5mg or Perphynazine 3~-5mg. In animal experiments analgesia effect with stimulation frequency of 5HZ was compared with that of 100 HZ. we tested the inhibition of compound action potential of saphenous nerve after stimulating for 30 minutes. The immediate effect upon stoppage of electric needling was rather good in case of 100 HZ.

3. Investigation of occipital headache after operations under acupuncture anaesthesia using point Futu showed that excessive strong stimulation or sudden change of stimulating strength of electric needling might cause the sternocleidomastoid muscle strong twitch-ings probably leading to occipital headache, or it was related to the patient's posture during the operation. Regulation of electric needling strength and proper position of the neck might prevent its occurrence.
