title: Evidence for the clinical management of chorioamnionitis.
abstract: Acute chorioamnionitis or intra-amniotic infection is defined by maternal fever in association with at least one additional clinical criterion including maternal or fetal tachycardia, maternal leukocytosis, uterine tenderness, or foul amniotic fluid odor. In clinically uncertain cases, the diagnosis can be augmented by routine laboratory studies (e.g. white blood cell count and differential count and acute phase reactants) and assays done on amniotic fluid. In general, the clinical management of chorioamnionitis is based on observational or cohort studies; only a few randomized controlled trials have been done. Prompt administration of antibiotics and delivery decrease maternal and neonatal morbidity. The most commonly used antibiotic regimen is ampicillin and gentamicin. Recent evidence supports daily rather than three-times-daily dosing of gentamicin for greater efficacy and decreased fetal toxicity. There is no evidence demonstrating harm with the administration of corticosteroids (to promote fetal lung maturity) in women with acute chorioamnionitis. Cesarean delivery should be reserved for standard obstetric indications.
