The clinical practices have shown a significant individual variance in efficacy of acupuncture anathesia. In this paper, we sum up in 600 cases of pneumonary lobectomy, thyroidectomy, total hysterectomy and total laryngectomy under acupuncture anaesthesia to find out whether there is any correlation between certain physiological parameters and the efficacy of anaesthesia. The rate of coincidence has been found to be 70-88%.
The physiological parameters used were pain-tolerance threshold, temperature of palm and index finger, respiratory movement, finger blood volume, galvanic skin response (GSR) and vertex potentials. The efficacy of acupuncture anaesthesia was divided into two grades: good (clinical I, II grade), poor (clinical III, IV grade). The result are as follows:
1. The efficacy of acupuncture anaesthesia is apparently correlated with acupuncture endurance and the level of pain-toleration threshold (P<0.01).
2. After acupuncture, when the changes of skin temperature are of elevating pattern, after-elevating pattern and high stable pattern, the efficacy of acupuncture anaesthesia would be good mostly; those of descending pattern would be poor mostly. The efficacy of acupuncture anaesthesia is apparently correlated with the pattern of changes of the skin temperature (P<0.01).
3. After acupuncture, the inhibitory reactions of GSR, finger blood-volume and amplitude of vertex potential are correlated with the efficacy of acupuncture anaesthesia (P<0.01).
4. No statistical significance has been found between the effect of acupuncture on respiratory (frequency, ventilation volume and average amplitude of respiratory waves) and the efficacy of acupuncture anaesthesia (P>0.05). But in cases in which the respiration was smooth and stable, or after acupuncture the respiration became smooth and stable, the efficacy would be good mostly.
The above facts indicate that the efficacy of acupuncture is probably correlated with the sympathetic inhibition of the automatic nervous system. The preliminary tests with different methods are of help in choosing patients suitable to acupuncture anaesthesia and afford clinical materials in studying the mechanism of acupuncture anaesthesia.
