RESUMO
Purpose:<br>We previously reported that using D-phenylalanine (D-PA) as a pre-medication increasingly enhanced acupuncture aneshesia effects occur. In order to investigate this effect clinically, we performed tooth extractions under acupuncture anesthesia using D-PA as a premed.<br>Method:<br>We divided the patients in the oral surgery department of our hospital for whom acupuncture-moxibustion was determined indicated, into 2 groups, a test group (9cases) to which D-PA (4.0g) was administered 30minutes prior to acupuncture anestesia, and an acupuncture anesthesia only group (about 31cases), and comparitively examined results.<br>The points used were: LI-4 on both sides in all cases, and indicated local points selected from among JOKAN, ST-7, GV-26, ST-2, LI-20, CV-24, ST-6, SI-18 and ST-5. Needles were inserted (in some cases a point surface electrode was used) and the acupuncture sensation aroused, following which low frequency current at 3-15Hz was administered.<br>The tooth extractions were begun about 30minutes later. The standard for determining results was a score of 1=absolutely no pain, 2=slight pain, 3=very painful, 4=a small amount of local anesthesia administered, as supplement, 5=attempt to use acupuncture anesthesia abandoned.<br>Results:<br>In the control group effective results (score 1 or 2) were obtained in about 30% of the cases while in the test group there was almost no need for supplementary local anesthesia and generally effective results were obtained in most cases.<br>Summary:<br>The results were more excellent in the group in which D-PA was used as a pre-med for tooth extractions with acupuncture anesthesia than in the group in which it was not used.
