Department of Anesthesia, Second Hospital, Hunan Medical College
Comprehensively preoperative estimations were made on 153 cases under acupuncture anaesthesia from Feb. to Aug. 1973 in our hospital. The items for estimation were: the state of consciousness, the test of pain threshold, the intradermic test of adrenalin, the measurement of temperature as well as the differentiation of disease according to the theory of traditional Chinese medicine, the psychologic and psychic factors concerned, and the collection of the history about the function of the vegetative nerves, etc. The results showed that the efficacy of acupuncture anesthesia had certain relationship with the state of conscious balance. The effect was good in subjects who showed unbalanced consciousness and was poor in those with balanced consciousness (P<0.001). The test of pain with potassium iontophoresis indicated that there was no significant difference in pain threshold between the efficacy of grade I with that of other grades before or after acupuncture. But there was marked change of pain tolerance threshold (P<0.05) after acupuncture. The pain tolerance threshold of the good acupuncture effect was elevated. Intradermic test of adrenalin manifested that the subjects whose approximate area of the white spots stopped its expansion after 20 minutes, showed good effect of acupuncture anesthesia and the effect was poor with those in whom the expansion still went on after 20 minutes (P<0.001). The observation of the temperature was made in one group with the measurement of tempearture at the nasal vestibule, and in another group with the temperature measurement at the palm. No matter which position was used for measuring the temperature, good effect all occurred in those who showed an elevation of temperature after acupuncture. But the temperature of the subjects with poor effect remained unchanged or decreased after acupuncture. There was a remarkable difference between the two groups (P<0.001).
The results of the other tests did not show anything regular or important.
We may conclude as following about the above four significant items. We found those whose consciousness was unbalanced, pain tolerance threshold increased after acupuncture, adrenalin test stopped its expansion after 20 minutes and the temperature elevated after acupuncture, all gave 100% good effect in acupuncture anesthesia. As for those who fitted 3 items, good effect came to 85.3%, and two items, good effect 80%, while one who fitted only one item of the four, 62.5%. Therefore, the comprehensively preoperative estimations mentioned above could increase the accuracy of predicting the efficacy of acupuncture anesthesia before operation.
