A 12-year-old male with a BMI of 45 kg/m², asthma and obstructive sleep apnea presents for an upper endoscopy for reflux. The patient’s caregiver reports heartburn, hoarseness, dysphagia, and frequent belching, which are unpredictable and worse when laying flat. He reports a bitter taste of regurgitated liquid 1 hour ago. What is the most appropriate anesthetic plan for this patient?
