Antibiotic prophylaxis at elective cesarean section: a randomized controlled trial in a low resource setting.

OBJECTIVE

To determine the best time to administer prophylactic antibiotics at Cesarean delivery in order to reduce the postoperative maternal infectious morbidity in a low resource setting.

MATERIAL AND

METHODS

One hundred term primigravidae with singleton pregnancy were recruited and randomly allocated to two equal groups. Each woman received 2 g intravenous Cefazoline. Women in Group I received it prior to skin incision while those in Group II had it immediately after cord clamping. We measured the following outcome parameters: (1) Surgical site wound infection; (2) Endometritis and (3) Urinary tract infection.

RESULTS

There was no significant difference in any of the patients' characteristics between both groups. In Group I, three cases developed surgical site infections but four in Group II (p > 0.05). In Group I, the infected cases had Cesarean because of malpresentations while in Group II, two cases had Cesarean because of patients' request, one because of maternal heart disease and one due to intra-uterine growth restriction. Seven and nine cases had urinary tract infection in Groups I and II, respectively, (p > 0.05).

CONCLUSION

Prophylactic antibiotic administration either prior to surgery or after cord clamping is probably equally effective in reducing the postoperative infectious morbidity after Cesarean in low resource settings.
