Venkatesh KK, et al. - The association of chorioamnionitis and its duration with adverse maternal outcomes by mode of delivery was investigated in this retrospective cohort study of singleton deliveries at ≥23 weeks of gestation (221,274 assessed deliveries, 62,331 by cesarean). Outcomes revealed increased odds of adverse maternal outcomes with cesarean delivery in correlation with chorioamnionitis, irrespective of its duration. The finding seems to be useful for care programs meant to prevent maternal morbidity after a cesarean complicated by chorioamnionitis.
