Incidence of Sleep-disordered Breathing and Upper Airway Collapsibility in Postpartum Patients and Its Intervention
Studieöversikt
Status
Intervention / Behandling
Detaljerad beskrivning
After obtaining study consent, each patient underwent measurements of upper airway cross-sectional area (CSA) during daytime within 48 h after delivery. The minimum upper airway CSA was measured using acoustic pharyngometry (Eccovision Acoustic Pharyngometry; Sleep Group Solutions, Inc) in sitting, 45° elevated, and nonelevated upper body position. This method has been previously used and validated in pregnant women.
In the patients who further gave consent for the sleep study, polysomnography (PSG) was performed throughout the entire study night. Within a crossover design, patients were randomly assigned to receive first either nonelevated or 45° elevated upper body position. Position was changed after 3.5 h by a member of the team.

Aktiv komparator: 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.

We conduct polysomnography in non-elevated 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.
