Abstract
There have been several recent reports condemning the unnecessary prophylactic use of antibiotics in the majority of surgical operations, particularly in the so-called clean cases.1-4 They have shown that these drugs do not prevent postoperative infections and that the incidence of antibiotic-resistant strains of bacteria increases.2,4 However, 2 aspects pertaining to this subject deserve further consideration. (1) The incidence of infection after a surgical procedure varies a great deal from one hospital to another.5-9 (2) The bacterial strains commonly found in a hospital environment might differ from one hospital to another. These facts explain, at least in part, the variability of incidence and severity of hospital-acquired infections found in different reports. Therefore, it seemed important both to observe the rate of wound infection in a general hospital such as in Salvador, Bahia (Brazil), and to perform a controlled clinical study on the effect of the prophylactic use
