Obstructive Sleep Apnea in Bariatric Surgical Patients

Purpose: The purpose of this study is to develop a novel pathway to decrease the cost and waiting time to manage bariatric surgical patients with obstructive sleep apnea. Hypotheses: Compared to the current perioperative pathway, the proposed novel pathway incorporating overnight oximetry and perioperative sleep apnea precautions is safe and more cost effective for evaluating and managing obstructive sleep apnea in the bariatric surgical patients. To decrease the cost and waiting time, we proposed a novel perioperative pathway to manage obstructive sleep apnea in the bariatric patients. In this pathway, the patient will be screened by the STOP-Bang questionnaire. The recruited patients will be randomized into two groups: The STOP-Bang questionnaire score is ≥4 then you will be assigned to any one of these groups * sleep study group (group 1) or * oximetry group (group 2).
