Brief Summary:
The aim of the study is to study whether training by residents or anesthesia assistants, on a recently introduced virtual-reality bronchoscopic simulator (ORSIM) improves performance of fiberoptic intubation in patients.

Condition or disease Intervention/treatment Phase
Endotracheal Intubation Device: Simulator (ORSIM) training Not Applicable

Detailed Description:

Traditionally, fiber optic bronchoscopy (FOB) intubation has been taught in a see one, do one basis. Modern training method in skill acquisition involves the use of simulators. Recently a portable, computer based, bronchoscopic simulator (ORSIM) was developed. The investigators hypothesized that operators trained with the ORSIM simulator will be more proficient in performing asleep FOB intubation than those trained with didactic teaching alone.

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.

The study results will impact on how FOB intubation will be taught effectively in the future.

Study Start Date : April 2015
Actual Primary Completion Date : June 2016
Actual Study Completion Date : June 2016

Arm Intervention/treatment
Experimental: Simulator arm
In the Simulation arm group the subjects will be trained on the virtual reality bronchoscopic simulator (ORSIM simulator) for up to 60 minutes as active intervention, before they undertake the 2nd Fiber optic intubations.
Device: Simulator (ORSIM) training
The simulator/intervention group will undergo training on the virtual reality bronchoscopic simulator (ORSIM) for 60 minutes before the subjects perform the 2nd Fiber optic intubation

No Intervention: Control arms
The control arm will be exposed only to the didactic teaching. The subjects will not undergo simulator training before undergoing 2nd fiber optic intubations.

Primary Outcome Measures :
  1. Performance of Fiberoptic intubation assessed by validated 40 point Global Rating Scale (GRS) [ Time Frame: 1 year ]

Secondary Outcome Measures :
  1. Success/Failure of Fiberoptic intubation [ Time Frame: 1 year ]
  2. The duration (in seconds) of the Fiberoptic intubation [ Time Frame: 1 year ]
