This randomized trial involves 34 consented residents or anesthesia assistants (AAs). In preparation, each consented person will view a teaching video of FOB intubation and tips. They will then perform an asleep FOBI in the OR under a staff anesthesiologist's supervision who's familiar with the study. Those who are randomized to the ORSIM group with undergo simulator training of 30-60 min. Those in the Didactic group will not undergo further training. Within about a week, the resident/AA will perform another asleep FOB intubation.
