[Clinical and experimental results with acupuncture-analgesia (author's transl)].

Operations under acupuncture analgesia have been performed in Vienna since March 1972. A total of 102 procedures has been performed with "classical" Chinese acupuncture analgesia. Additionally given analgesics, psychodynamic factors and neurophysiological components are of joint importance. Our success rate in these cases was 64 p.c. Since October 1972 we call "two-phase-acupuncture-analgesia". Up to June 1975 72 operations were performed under some modifications of this method. In a neurophysiological study 17 volunteers and in 2 patients undergoing stereothalamotomies depression or even disappearance of evoked potentials was be observed during acupuncture with alectrical stimulation. Thus an interaction between pain stimuli and acupuncture stimuli in the thalamus could for the first time be demonstrated in man.
