Evaluation of Sleep Disordered Breathing Following Ambulatory Surgery

Stopped early

Conditions studied: Sleep Disordered Breathing

In brief

Obstructive sleep apnea (OSA) is a relatively common medical condition that includes upper-airway obstruction and consequent cessation of breathing during sleep with significant associated other medical problems. The time period around surgery has been demonstrated to be an independent risk factor for various complications but the mechanism is not well understood. This protocol proposes to study the fundamental question of what changes occur in the postoperative setting to ambulatory patients with and without OSA by administering a validated "STOP-BANG" screening questionnaire and conducting preoperative and postoperative Home Sleep Testing (HST). In doing so, critical evidence shall be gained in the understanding of postoperative sleep disorder breathing changes associated with surgery and anesthesia. With evidence, sound perioperative management recommendations and policy may be developed to assist with caring for this large and at risk surgical population.
