Incidence of Sleep-disordered Breathing and Upper Airway Collapsibility in Postpartum Patients and Its Intervention

This study is currently recruiting participants. (see Contacts and Locations)

Matthias Eikermann, Massachusetts General Hospital
ClinicalTrials.gov Identifier:
NCT01719224
First received: October 30, 2012
Last updated: November 6, 2013
Last verified: November 2013
  Purpose

The investigators hypothesized that sleeping in a 45 degrees elevated body position decreases the likelihood of upper airway vulnerability to collapse. Furthermore, the investigators want to elucidate the anatomical and physiological risk factors that contribute in the upper airway obstruction in post-partum patients.

Further study details as provided by Massachusetts General Hospital:

Primary Outcome Measures:
  • Lower rate of sleep disordered breathing in elevated body position [ Time Frame: 48 hours after delivery ] [ Designated as safety issue: Yes ]
    We conduct polysomnography in supine and 45 degrees elevated body position, to show the effect of body position in context of sleep disordered breathing.We collect data of the apnea-hypopnea-index, central apneas, obstructive apneas and oxygen.


Secondary Outcome Measures:
  • to elucidate the anatomical and physiological risk factors that contribute in the upper airway obstruction in post-partum patients [ Time Frame: 48 hours after delivery ] [ Designated as safety issue: Yes ]
    We measure pulmonary function using spirometry, and have a look at MEF/MIF 50 Ratio, FIV 1, FVC and FEV 1. Furthermore we evaluate risk factors for upper airway dysfunction by using the STOP-Bang-Questionnaire, and Mallampati Scores, as well as anatomical landmarks (measuring inter-incisor gap, thyromental distance, sternomental distance, neck circumference).


Estimated Enrollment: 50
Study Start Date: March 2012
Estimated Study Completion Date: January 2015
Estimated Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Elevated body position
We collect data about the apnea- hypopnea index, obstructive and central apneas, as well as oxygen, by comparing supine to 45 degrees elevated body position.
Procedure: elevated body position
Active Comparator: supine body position
We collect data about the apnea- hypopnea index, obstructive and central apneas, as well as oxygen, by comparing supine to 45 degrees elevated body position.
Procedure: supine body position
