Neonatal Sleep Intervention to Improve Postpartum Hypertension

The Impact of a Neonatal Sleep Intervention on Postpartum Blood Pressure in Women With Hypertensive Disorders of Pregnancy

The investigators are conducting a single center, randomized controlled trial testing the impact of a neonatal sleep intervention, the SNOO, on reducing maternal blood pressure (BP) in the postpartum period in women with hypertensive disorders of pregnancy. The SNOO is a responsive bassinet designed to automatically calm and consolidate infants by responding to their cries. Use of the SNOO has been demonstrated to improve infant sleep by 1-2 hours nightly, thus increasing maternal sleep time. The investigators plan for 110 women with pregnancies complicated by gestational hypertension or pre-eclampsia to be randomized 1:1 to either receive and use the SNOO responsive bassinet for their infants, or to receive the usual care of safe sleep education. Women will be followed longitudinally through 6 months postpartum with serial BPs, weights, mood assessments, and subjective and objective sleep assessments. The investigators hypothesize that for women with pregnancies complicated by gestational hypertension or preeclampsia, that poor maternal sleep quality contributes to increased BP in the postpartum period. The investigators further propose that compared to usual care (safe sleep education), an intervention targeted to improve neonatal sleep (the SNOO), and thus maternal sleep, will improve postpartum BP for these women.
