NCT02383706

Brief Summary

Obstructive sleep apnea (OSA) is a risk factor for complications during pregnancy and current screening tools for OSA have not been shown to be reliable in pregnant women. The primary aim of this study is to develop a valid screening tool to identify at-risk pregnant women, so that they can be further evaluated and treated. Women with OSA may also be at risk for respiratory complications related to opiate administration for post-cesarean delivery pain. A secondary aim of this study is to evaluate post-operative minute ventilation in women who undergo cesarean delivery using a novel method of non-invasive minute ventilation monitoring.

Outcome Measures

Primary Outcomes (2)

  • Number of Participants With a Negative Obstructive Sleep Apnea (OSA) Home Sleep Test Result

    Determined using the Apnea-Hypopnea Index (AHI). Participants were considered OSA-negative if experienced less than five events per hour.

    Women studied at one time point between 24 weeks and 35 weeks gestation.

  • Number of Participants With a Positive Obstructive Sleep Apnea (OSA) Home Sleep Test Result

    Determined using the Apnea-Hypopnea Index (AHI). Participants were considered OSA-positive if experienced five or more events per hour.

    Women studied at one time point between 24 weeks and 35 weeks gestation.

Secondary Outcomes (1)

  • Post-op Minute Ventilation Following C-section

    Women studied for 24-hours following their cesarean delivery.
