103 patients with thyroid diseases were operated upon under electro acupuncture anesthesia from January to September, 1975. The cases were classified into three groups, namely Group Hegu and Neiguan, Group Futu and Group of auricular acupuncture. The total effective rate was 99.1% and the excellent rate 89.4%. The best analgesic effect was produced in the first group statistically.
At the time of dividing the neck muscles and resecting the glandular corpus, analgesic effects were equally good in all groups. However, during the procedure of incising skin, the anesthetic effect achieved by acupuncture in Group Hegu and Neiguan were superior to those in the other groups.
The operations successfully performed under acupuncture anesthesia were extirpations of cyst or adenoma of thyroid and subtotal thyroidectomies. Prolongation of induction time had no effect on the reinforcement of analgesia.
In 16 cases, the 24-hour level of vanillyl mandelic acid (VMA), a metabolite of catecholamine in urine, was determined on the day before and after the operation. The postoperative level in all cases but one, were elevated significantly, indicating indirectly an increase of catecholamine. This is in a certain sense related to the mechanism of acupuncture anesthesia as it has been pointed out in literature that the level of catecholamine is elevated along with that of the pain threshold.
Spirograms were recorded in 18 cases and electromyograms of corrugator in 20 cases. The changes were mainly in correspondence with the results of clinical grading. Though the amplitudes of the corrugator electromyograms in all the cases were augmented during the principal surgical procedures, there was no much increase of amplitude in the Grade I cases. On the other hand, in the Grade III cases, an evident increase was noticed and the amplitudes were generally raised to levels higher than 150 microvolts.
Of the 103 cases, 47 were randomly selected and grouped into different types on the diagnostic basis of traditional Chinese medicine. No relationship between the clinical typing and analgesic effects was noted. In addition, "needling test" was carried out before operation. 84.8% of the "Grade I and II" cases were confirmed, whereas merely 21.9% of the "Grade III" cases corresponded to the conclusive grades after operation. Therefore the results of the "needling test" should not be taken as perfectly reliable.
