Choice of antibiotics for infection prophylaxis in emergency cesarean sections in low-income countries: a cost-benefit study in Mozambique.

Background: There is a need to assess the cost-benefit of different models of antibiotic administration for the prevention of post cesarean infection, particularly in resource-scarce settings.

Design: Randomized, nonblinded comparative study of a single combined preoperative dose of gentamicin and metronidazole vs. a post cesarean scheme for infection prophylaxis.
