Ultrasound-Guided Superior Laryngeal Nerve Block Facilitates Anesthesia Management in Bariatric Surgery

Patients with obesity usually have a narrow pharyngeal cavity. They are prone to exposure difficulties and intubation failure during endotracheal intubation, and even face mask oxygen supply difficulties and hypoxemia in severe cases. We described the successful completion of conscious endotracheal intubation with superior laryngeal nerve internal branch block (SLNi) in a patient with pathologic obesity.A 29-year-old, nondiabetic man with severe obesity (weight 211 kg, height 186 cm, and body mass index [BMI] 60.99 kg/m
