A prospective, randomized, clinical study was carried out in 188 patients undergoing appendicectomy or colorectal surgery to test the efficacy of prophylactic, parenterally-administered antibiotics in the prevention of infection. The results show the effectiveness of the association gentamicin-metronidazole (9.4% of infections), compared to the control group with no antibiotics (39.1% of infections), X2 = 14.1; P less than 0.001).
