title: Management of pain after abdominal surgery: dipyrone compared with pethidine.
abstract: 1 Dipyrone 2.5 g was compared with pethidine 100 mg in a double-blind parallel group study. 2 Patients with moderate or severe postoperative pain following abdominal surgery received one of the two drugs intramuscularly. 3 The two treatment groups were homogeneous when analyzed by age, weight, height, sex, and initial severity of pain. 4 The onset degree and duration of pain relief afforded by both drugs was similar when the groups were compared as a whole or according to initial pain level. 5 No side-effects were attributed to either drug in this study.
