Abstract

Objective: The objective of this study was to determine whether prophylactic treatment with oral broad-spectrum antimicrobial therapy improves pregnancy outcomes in twin gestations.

Methods: Patients with twin gestations between 24 and 32 weeks were randomized to receive amoxicillin/clavulanic acid or placebo. Those patients randomized before 24 weeks received a 1-week course at 24 and at 28 weeks gestation. Those patients entered later than 24 weeks received a 1-week course either at 28 weeks or at enrollment (up to 32 weeks). Other than antibiotic use, the management of the groups was identical and unchanged from the routine care of twin gestations.

Results: Of 149 twin pregnancies enrolled, 76 were randomized to the drug group and 73 to the placebo group. There was no significant difference in mean gestational age at delivery (35.9 vs. 35.7 weeks), birth weight (2,358 vs. 2,344 g), mean neonatal nursery stay (9.9 vs. 11.7 days), or respiratory distress syndrome (6/76 vs. 4/73) in the drug vs. placebo group, respectively.

Conclusions: The addition of prophylactic oral broad-spectrum antimicrobial therapy to the standard antepartum management of twin gestations had no demonstrable effect on the gestational age at delivery, birth weight, or neonatal complications. There did not appear to be any beneficial effect of the prophylactic use of amoxicillin/clavulanic acid in this clinical setting.
