NCT01697878

Brief Summary

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).

Outcome Measures

Primary Outcomes (1)

  • apnea hypopnea index (AHI)

    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.

    preoperatively for one night of sleep and during 2 hours of recovery room stay

Secondary Outcomes (1)

  • apneas after opioid bolus self-administration

    5 minutes after each opioid PCA administration

Study Arms (2)

Randomization Group 1

EXPERIMENTAL

CPAP first followed by standard of care

Procedure: CPAP followed by atmospheric pressure

Randomization group 2

ACTIVE COMPARATOR

Standard of care followed by CPAP

Procedure: Atmospheric pressure followed by CPAP

Interventions

In the PACU, Patients receive 2 hours of continuous-positive-airway-pressure (CPAP) oxygen at 30% FiO2 treatment followed by 2 hours of oxygen treatment (6 L O2/min) that is part of standard of care at Massachusetts General Hospital

Also known as: Tx Plan 1
Randomization Group 1

In the PACU, patients receive 2 hours of Oxygen treatment (6L/min) that is part of standard-of-care at Massachusetts General Hospital, followed by 2 hours of Continuous Positive Airway Pressure (CPAP) treatment at 30% FiO2.

Also known as: Tx Plan 2
Randomization group 2
