title: Prophylaxis with trimethoprim-sulfamethoxazole in abdominal, pelvic, and prostatic surgery.
abstract: The literature on use of trimethoprim-sulfamethoxazole (TMP-SMZ) for prophylaxis in abdominal, pelvic, and prostatic surgery is meager. There is some evidence that TMP-SMZ may be effective prophylactically in biliary surgery (in patients with functioning gall bladders). Further study is needed to clarify the mixed results seen in prostatic and pelvic surgery. An evaluation was made of the effectiveness of TMP-SMZ in the prevention of endomyometritis following cesarean section in 206 women who were comparable in terms of risk factors. Among patients given a placebo, a total of 44 infections (42%) occurred, whereas among those given TMP-SMZ prophylaxis, 22 infections (22%) occurred, a statistically significant difference (P = .037, chi 2). The rate of endomyometritis among placebo recipients was 33%, as contrasted with one of 19% in those given TMP-SMZ (P = .02, chi 2). Prophylactic treatment resulted in lower rates of endomyometritis in both high- and low-risk women, but the results reached statistical significance only among high-risk patients. In essence, prophylaxis changed high-risk patients into low-risk patients.
