Interventions

Procedure/Surgery : Anesthesia induction and perioperative management will be performed identically in both groups. Tracheal intubation will be conducted by one of four board-certified anesthesiologis

failure is defined as periephral oxygen satuation 180 seconds, after which appropriate rescue is performed. In addition to first-attempt success rate, assessments include glottic view (Cormack-Lehane
