Consequences of Obstructive Sleep Apnea on Respiratory Function Following Weight-loss Surgery

Consequences of Obstructive Sleep Apnea on Respiratory Function Following Weight-loss Surgery: A Randomized Controlled Trial
The investigators propose to compare two different treatments, continuous positive airway pressure (CPAP) versus breathing of atmospheric pressure, in subjects with obstructive sleep apnea (OSA)recovering from weight loss surgery in the post anesthesia care unit (PACU).
WE hypothesize that subjects with OSA will have a higher Apnea-Hypopnea Index (AHI) with desaturation and the investigators expect that post-operative CPAP treatment in the PACU will significantly improve the AHI and therefore improve patient safety in the PACU.
The investigators also hypothesize that subjects with OSA have a greater decrease in oxygen saturation in response to opioid administration by patient-controlled opioid analgesia (PCA).

Detaljert beskrivelse
Patients with morbid obesity have an approximately 60-80 percent incidence of OSA depending on the criteria used for making diagnosis, and they are suggested to be at increased risk to develop serious perioperative complications, especially during the postoperative period.
Weight loss might be considered as an appropriate treatment of OSA but in turn it has recently been reported that OSA is an independent risk factor for development of perioperative complications, importantly oxygen desaturation, in patients undergoing weight loss surgery.
It seems logical to evaluate if these patients would benefit from post-operative CPAP treatment in the PACU.
The results of this multidisciplinary study will have an impact on PACU treatment of patients with OSA and will further optimize patient care at MGH.

apnea hypopnea index (AHI)
Tidsramme: preoperatively for one night of sleep and during 2 hours of recovery room stay
|
The AHI is assessed for one night's sleep in the initial at-home sleep study conducted with a portable Alice monitor.
Subsequently, the AHI is assessed during the patient's stay in the post-anesthesia-care unit (PACU) during which time they receive CPAP and oxygen treatment.
