The conclusions that can be drawn from this meta-analysis are limited due to the small number of studies. For none of the outcomes was a statistically significant difference seen between the different interventions. Current consensus is for the intrapartum administration of antibiotics when the diagnosis of intraamniotic infection is made; however, the results of this review neither support nor refute this although there was a trend towards improved neonatal outcomes when antibiotics were administered intrapartum. No recommendations can be made on the most appropriate antimicrobial regimen to choose to treat intraamniotic infection.

Anaerobic coverage for intra-amnionic infection: maternal and perinatal impact.
Although intrapartum antibiotics are beneficial to both the mother and newborn, there is no consensus as to the most efficacious antibiotic regimen in the treatment of intra-amnionic infection, especially with regard to anaerobic coverage. We randomized pregnant women with intra-amnionic infection to receive either dual agent therapy (ampicillin and gentamicin) or triple agent therapy (ampicillin, gentamicin, and clindamycin). The frequency of vaginal and cesarean delivery was similar in both groups. There was no significant difference in the incidence of endometritis between the two groups (10 of 69 versus 5 of 64; p = NS). There were no significant differences in either neonatal morbidity or mortality. The addition of clindamycin to provide anaerobic coverage for intra-amnionic infection does not significantly alter the incidence of endometritis in women delivered by cesarean section, although it may have an impact on women delivering vaginally.
