Use of Nitrous Oxide Donor for Labor Induction in Women With PreEclampsia

Summary

A randomized controlled trial (RCT) of nitric-oxide donor (NOD) isosorbide mononitrate (IMN) versus placebo as an adjuvant to misoprostol/ intra-cervical Foley bulb for induction of labor to decrease rate of cesarean deliveries in pregnancies complicated by preeclampsia (≥24/0 weeks' gestation)
