Brief Summary

A randomized controlled trial of 1,500 women to assess whether treatment of obstructive sleep apnea with continuous positive airway pressure (CPAP) in pregnancy will result in a reduction in the rate of hypertensive disorders of pregnancy.

Detailed Description

Emerging data support a link between sleep disordered breathing (SDB) and adverse pregnancy outcomes. In particular, women with obstructive sleep apnea (OSA) appear to be at increased risk of both hypertensive disorders of pregnancy and gestational diabetes. In the non-pregnant population, OSA is typically treated with continuous positive airway pressure (CPAP) during sleep and has been shown to reduce blood pressure in hypertensive patients. Unfortunately, data on whether maternal and neonatal outcomes could be improved with treatment of OSA during pregnancy are extremely limited. This study aims to address this knowledge gap.

A randomized controlled trial of 1,500 women to assess whether treatment of obstructive sleep apnea with continuous positive airway pressure (CPAP) in pregnancy will result in a reduction in the rate of hypertensive disorders of pregnancy.
