PIPERACILLIN MONOTHERAPY COMPARED WITH METRONIDAZOLE AND GENTAMICIN COMBINATION IN PENETRATING ABDOMINAL-TRAUMA

The therapeutic efficacy and safety of piperacillin (4.5 g, every 6 hours) were compared with combined gentamicin (80 mg, every 8 hours) and metronidazole (500 mg every 6 hours) therapy in 246 patients hospitalized for penetrating abdominal injuries. Sixty-five patients had penetrating injury of the colon, rectum, or terminal ileum. The overall clinical cure rate was about 94% in both treatment groups. Adverse clinical experiences or biochemical abnormalities required discontinuation of therapy in three patients on gentamicin/metronidazole and in no patients on piperacillin.
