Reliability of Sleep Questionnaires in Detecting SDB in Cardiac Surgery Patients

PURPOSE: The perioperative management of surgery patients can be seriously complicated by Sleep Disordered Breathing (SDB). Sleep questionnaires are sometimes used to identify patients suspected of SDB before surgery; however, the reliability of these questionnaires in cardiac surgery patients has not been investigated. The purpose behind this study is to assess the reliability of sleep questionnaires in detecting SDB in cardiac surgery patients pre-operatively.
