Validate the MASCAN score for predicting difficult facemask ventilation

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective observational external validation of the MASCAN score in adults undergoing general anesthesia who require facemask ventilation and tracheal intubation. Study staff will record MASCAN components and real-world ventilation practices, including timing of neuromuscular blocking agents and whether mask ventilation is manual or controlled. Investigators will also collect visual assessments of the capnography waveform and compare first-attempt intubation success as reported by the airway operator versus an independent observer. No experimental interventions are applied; the study observes routine clinical care at a single center.
