Study Summary
This prospective, randomized, double-blind study is intended to enroll a total of 100 patients with a BMI ≥ 40 kg/m2 and another 100 patients with a BMI ≥ 30 kg/m2 (but less than 40 kg/m2) undergoing surgery with general endotracheal anesthesia at Parkland Hospital. Patients will be randomized to receive either 15 L/min O2 or 15 L/min air from a standard nasal cannula during a simulated prolonged laryngoscopy. The anesthesia provider will do a direct laryngoscopy to ensure that the patient has a Cormack-Lehane grade I-II airway. Patients who have grade III-IV airways will be excluded from further study procedures and not analyzed. The rest of the anesthetic will not deviate from the standard of care. Anesthesia providers will be blinded as to whether patients are receiving oxygen or air during the apneic period.
Primary Outcome
To determine whether apneic oxygenation via nasal cannula oxygen results in a longer period of apnea (SpO2 ≥ 95%) during a simulated prolonged laryngoscopy in obese and morbidly obese patients.
