Apneic Oxygenation During Prolonged Laryngoscopy in Obese Patients: A Randomized, Controlled Trial of Buccal RAE Tube Oxygen Administration.

BACKGROUND:Despite optimal preoxygenation, obese patients undergoing induction of general anesthesia exhibit significant hypoxemia after 2 to 4 minutes of apnea. Apneic oxygenation techniques can assist airway management by extending the safe apnea time. We hypothesized that a novel method of apneic
