[Postoperative analgesia for ambulatory surgery in children: a comparison of 2 techniques].

In 40 children scheduled for circumcision, we studied the quality and the adverse effects of postoperative analgesia induced by caudal block (group 1) or acetaminophen by rectal route (group 2). Study lasted the six first postoperative hours. In recovery room, analgesia was more effective in group 1. Need of analgesic drugs was also lesser in group 1. Incidence of adverse effects was the same in the two groups.
