Perioperative incidence of airway obstructive and hypoxemic events in patients with confirmed or suspected sleep apnea – a prospective, randomized pilot study comparing propofol/remifentanil and sevoflurane/remifentanil anesthesia

OSA is a risk factor for perioperative complications, however data on the impact of various anesthesia regimens on postoperative outcome is scarce. Randomized controlled study to assess the impact of propofol/remifentanil versus sevoflurane/remifentanil based anesthesia on nocturnal apnea-hypopnea index (AHI) and oxygen saturation. Neither the volatile agent sevoflurane nor the intravenous anesthetic propofol altered nocturnal AHI or oxygen saturation when combined with the short acting opioid remifentanil.
