Observations were made on channel phenomena (by various methods of the test for sensational propagation throught channel (SPTC) and the acupuncture analgesia related to time and space), symptomatic classification according to the dialetric methods of traditional Chinese medicine and the temperature of vestibulum nasi in over 130 surgical patients in order to clarify the relation between the effect of acupuncture anesthesia and the factors mentioned above. The results are follows:
1. In the group of 53 cases of ligation of oviduct the test of SPTC with lowfrequency electrostimulation at Jing point had a positive rate of 25%. The effect of acupuncture anesthesia were better in patients who were slightly sensitive than in those who were not sensitive at all.
2. Hegu, Zusanli or Sanyinjiao were needled accordingly to test SPTC on 62 patients prepared for operations of gall bladder or stomach; the positive rate was 38%. No obvious relation was found between the degree of sensational propagation and the effect of acupuncture anesthesia.
3. Hegu, Zusanli or Sanyinjiao were needled accordingly on 76 patients to be operated on for various troubles. The test of pain thresholds were carried out at 2 channel points along the large intestine channel, stomach channel or spleen channel or at another two non-channel points out of the above mentioned channels. It was found:
(1) The pain thresholds rised markedly following the puncture, and was irrespective to the points selected. It was not merely limited to the distribution along channels.
(2) Needling Hegu, Zusanli (Yang channels) brought about a quicker rise of pain thresholds while puncturing Sanyinjiao (Yin channels) showed less speed in the rise of pain thresholds.
(3) The effect of acupuncture anaesthesia was related to the basic pain tolerance thresholds. There were obviously higher basic pain tolerance thresholds in the group of grade I (excellent) and II (satisfactory) than in the group of grade III (fair) and IV (poor) in analgesic effect.
4. The temperature in vestibulum nasi rose in all the 62 cases. The analgesic effect were excellent and satisfactory (grade I, II) in patients whose temperature rise was not over 1ºC. 10 minutes after needling, and in cases exceeding 1ºC less effect was found.
5. The symptomatic classification of types in traditional Chinese medicine: It was found by the analysis of 62 cases that typical cases of Yang difficiency had the highest rate of excellent and satisfactory analgesic effect which reached 83%, whereas typical cases of Yin difficieny had only a rate of 57.1%. Those not typical were in the intermediate.
6. The facts of our observations show that quite satisfactory analgesic effect appeared in patients of Yang difficiency or of less rise of the temperature in vestibulum nasi after needling.
Statistics show that effect of acupuncture anesthesia were excellent and satisfactory in patients conforming with the 3 criteria mentioned above. On the contrary, it had only an excellent and satisfactory rate of 25% in those conforming with none of the 3 criteria.
