About this study

Official title: 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SNOODevice

    The SNOO is a commercially available device which is a responsive bassinet for neonates. The bassinet is designed to respond to the infant's cries and automatically respond by emitting engineered white noise sounds and providing a rhythmic rocking motion. The infant is also swaddled to remain securely back-down. The SNOO automatically increases the emitted sound and motion if the infant is still crying. However, if the infant does not settle within 3 minutes, the SNOO will shut off and alert the adults for additional assistance. Parents can also modify the SNOO settings to meet the baby's need for sound and/or motion.

  • Safe sleep education in the postpartum periodOther

    Comprised of education from the postpartum clinical nurse with a corresponding educational handout to take home

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean Arterial Pressure

    Mean arterial pressure will be calculated from the systolic and diastolic blood pressures [(2 * diastolic blood pressure + systolic blood pressure) / 3] assessed using a study-provided blood pressure cuff at the time of the study follow-up visit.

    Measured: 6 weeks postpartum

Secondary outcomes (35)

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 8 Jun 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean Arterial Pressure (time frame: 6 weeks postpartum). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04864249, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jun 2023; AzTrials last refreshed its copy on 1 Nov 2026.
