Analyzing sleep changes after anesthesia in patients with obstructive sleep apnea

The SNORE-trial: Postoperative REM-Sleep Disturbance iN Obstructive Sleep-apnea Patients and the Relation With AH-index

Observational Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) · NCT06586268

This study is testing how sleep patterns change after surgery in people with obstructive sleep apnea to see if these changes get worse over a few nights.

What this trial studies

This observational study aims to investigate how sleep patterns change following anesthesia and whether these changes correlate with the severity of obstructive sleep apnea (OSA) in patients after surgery. Participants diagnosed with OSA will wear a device called WATCHPAT to monitor their sleep stages and record incidents of apnea and hypopnea over three nights post-operatively. The study will assess whether the severity of OSA increases from the first to the third night after surgery and how this relates to REM sleep. Data will be collected non-invasively, allowing for a comprehensive analysis of sleep disturbances in the post-surgical period.

Who should consider this trial

Good fit: Ideal candidates are adults scheduled for elective surgery who have a diagnosis of obstructive sleep apnea, with or without treatment.

Not a fit: Patients under 18 years old or those not speaking Dutch or English may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for patients with obstructive sleep apnea following surgery.

How similar studies have performed: While there have been studies on sleep apnea, this specific approach of analyzing post-anesthesia sleep changes is relatively novel.
