Ambulatory surgery minimally impacted sleep parameters for patients with obstructive sleep apnea (OSA). No increase in adverse events was observed in treated or untreated OSA patients undergoing outpatient procedures.
Area of Science:
- Anesthesiology
- Sleep Medicine
- Surgical Outcomes
Background:
- Obstructive sleep apnea (OSA) poses perioperative risks in ambulatory surgery.
- Limited data exist on managing OSA patients in outpatient surgical settings.
Purpose of the Study:
- To evaluate changes in perioperative sleep parameters in ambulatory surgical patients.
- To assess the impact of ambulatory surgery on individuals with OSA.
Main Methods:
- Prospective, observational study of 166 ambulatory orthopedic surgery patients.
- Three unattended home sleep apnea tests: pre-surgery, post-surgery night 1 (N1), and post-surgery night 3 (N3).
- Anesthesia and surgical teams were blinded; patients received routine care.
Main Results:
- 40% of patients had OSA at baseline; 64.5% of those with prior diagnosis used CPAP.
- No significant changes in respiratory event index or SpO2 nadir postoperatively.
- Increased time with oxygen saturation < 90% at N1 compared to baseline for most patients, excluding moderate-to-severe OSA.
Conclusions:
- Ambulatory surgery demonstrated minimal effects on sleep parameters.
- No increased adverse events were noted in patients with treated or untreated OSA.
