The SNORE-trial: Analysis of Alterations in Sleep Stages Following Anesthesia and Their Relation to the Severity of Obstructive Sleep Apnea in the First 3 Nights After Surgery

Recruiting now

Conditions studied: Sleep Apnea Syndrome, Obstructive, Sleep Apnea Syndrome (OSAS)

In brief

The goal of this observational study is to learn about the relationship between sleep alterations following anesthesia and their relationship to a potential increase of obstructive sleep apnea (OSA) severity. Our main question is: Is there an increased severity of OSA on the third post-operative night compared to the first post-operative night and does this have a relation with REM sleep? Participants enrolled in this research are all diagnosed with OSA, with or without treament. All participants will be asked to wear a watchlike device called WATCHPAT to identify sleep paterns and register apneic (no breathing) and hypopneic (insufficient breathing) incidents. We ask our participants to wear this device for 8-10 hours a night when they are a sleep.
