Observations have been made on a group of 1,293 cases of various surgical operations under acupuncture anesthesia. The effect is shown in the following table:
On the basis of the observations mentioned above, the clinical features of acupuncture anesthesia can be outlined as follows:
(1) The effect of acupuncture anesthesia is closely related to the selection of points and the parameters of stimulation. The points should be selected according to (1) the course of channels, and (2) nerve distribution. Additional paraincisional points may promote the analgesic effect. In general, high frequency electric stimulation is applied for points of trunk and low fresuency for points of limbs. Intensity of stimulation must be tolerable or without uncomfortable feeling to the patients.
(2) The effect of acupuncture anesthesia is also related to the location and type of operation as well as the surgical manipulation. The points have only relative specificities and the analgesic effect induced by needling is limited.
(3) The relationship between the effect of acupuncture anesthesia and the individual difference and the condition of disease. The individual difference of acupuncture effect is very significant, which may be preestimated in many aspects. For the cases of emergency or shock, acupuncture anesthesia is quite effective. The 12 cases of shock except one in present group are successful, and the operative procedure was smooth, the results effective.
In the present group, comparison has been made in 633 cases of operations with recorded documents, in which 388 cases retained the needle, with the successful rate 87.87% and excellent rate 60.95%, and 295 cases without retaining of the needle with successful rate 91.53% and excellent rate 60.68%. Thus for minor operations, retaining of the needle is omitted.
In 20 cases of control group and 15 cases of operation group EEG, EMG, weak twitching of muscle, respiration, plethymogram and galvanic skin reflex, etc. were observed. Preliminary results indicated that these items can be used as objective indices for pain in acupuncture anesthesia, among which the plethymogram and EEG were used as reference for preestimation of the acupuncture effect.
