Background  Hypoxia is a major concern and cause of morbidity or mortality during tracheal intubation after anesthesia induction in a pathological obese patient with obstructive sleep apnea (OSA). We introduce a case using Supraglottic jet oxygenation and ventilation (SJOV) to promote oxygenation/ventilation during fiberoptic intubation in a paralyzed patient with morbid obesity and OSA.    Case presentation  A 46-year-old man weighting 176 kg with BMI 53.7 kg/m2 was scheduled for gastric volume reduction surgery to reduce body weight under general anesthesia. SpO2 decreased during induction, and two hand pressured mask ventilation partial failed. We then placed WEI Nasal Jet Tube (WNJ) in the patient’s right nostril to provide SJOV. Then fiberoptic bronchoscopy guided endotracheal intubation was performed via mouth approach, and vital signs were stable. The operation was successfully completed after 3 h. Patient recovered smoothly in hospital for 8 days and did not have any recall inside the operating room.    Conclusion  SJOV via WNJ could effectively maintain adequate oxygenation/ventilation during long time fiberoptic intubation in an apnea patient with morbid obesity and OSA after partial failure of two hand pressured mask ventilation, without obvious complications. This may provide a new effective approach for difficult airway management in these patients.
