Obese patient
Conditions
Interventions
Group A:Group A subjects were subjected to a modified induction intubation protocol. Airway anaesthesia (ultrasound-guided supraglottic nerve block + cricothyroid puncture) was administered first. Sub
Group B:In group B, subjects underwent rapid sequential induction endotracheal intubation, the patient mask inhaled pure oxygen for pregenation before induction until the exhaled oxygen concentration
