Effect of Acupuncture ANESTHESIA in Intrauterine Curettage (Part II)

Abstract

(1) Some improvements were made in the score table used for evaluation of effectiveness in the previous studies.
(2) The number of the cases evaluated was incresed.
(3) The difference in effectiveness of acupuncture anaesthesia and the doctors' skill of operation, the factor which influences painfulness, were also examined.
(4) The measurement of palm-forearm skin potential was employed as an objective evaluation of pain.
METHODS
Acupuncture anaesthesia was undertaken using Neurometer NAJ. Induction was done through Chinese needles (2 inch no. 28) inserted on Zusanli and Sanyinjiao for 20 minutes.
The evaluation was done on 413 cases which underwent intrauterine curettage under acupuncture anaesthesia in 1982-1985.
The evaluation of the effectiveness was carried out in two ways: (1) using scores based on the observation of patient's expression of the face and other signs, and (2) subjective evaluation (questionnaire) during the operation.
The skin potential was measured between the electrodes applied to the palm and the forearm using ECG (Fukuda-DU3S).
The relationship was examined between the potential and pain during the operation was examined. (10mm-25mm/sec, 0-8mmV)
RESULT
(1) As a result of the improvement in the score table, the effectiveness rate obtained from the questionnaire and that from the score table were close enough to conough to confirm its utility.
(2) Less effectiveness of acupuncture anaesthesia was obtained in the patients classified into the “type of unbalanced autonomic nervous system” according to the classification of the CMI test modified by Majima. This result was coincide with the previous report.
(3) Among five doctors, one obtained the best effective rate of 63%, and others got those of 14-26%.
(4) In the measurement of the potential between the palm and the forearm, values of 0.1-8.0mV appeared. Although there was a tendency that the severer the pain was, the higher the potential was, the actual value of this measurement as a rating method is to be examined.
