NCT02263300 | Completed

Brief Summary

Does spatial orientation of a novice in relation to a mannequin (supine vs upright) impact on the development of fiberoptic intubation skills? Is it necessary to teach both orientations or is the supine view transferable to the upright position? Which method demonstrates longer skill retention? The hypotheses: Both orientations must be practiced and the upright skill is harder to learn but is retained for longer.

Outcome Measures

Primary Outcomes (1)

• Elapsed time to mannequin intubation with fiberoptic scope.

  The elapsed time of intubation with fiberoptic scope of a mannequin. Stop watch is started at passing teeth and ends when scope reaches carina.

  2 minutes

Secondary Outcomes (2)

• Global rating scale (GRS)

  2 minutes

• Examiner check list (ECL) scores

  2 mintues

Study Arms (4)

Supine- Supine

Group A (supine-supine) will first practice fiberoptic intubation with the iLarynx oriented in the supine position. Learning curves, global rating scale and checklist will then be obtained by a blinded examiner with the medical student using a real fiberoptic on a mannequin oriented in the SUPINE then UPRIGHT position. At the end of one week,the same medical student will then perform the intubation with the mannequin in both positions.

Upright-upright

Group B (upright-upright) will first practice fiberoptic intubation with the iLarynx oriented in the upright position. Learning curves, global assessment score and checklist will then be obtained by a blinded examiner with the medical student using a real fiberoptic on a mannequin oriented in the UPRIGHT then SUPINE position.At the end of one week, the same medical student will then perform the intubation with the mannequin in both positions.

Supine -upright

Group C( supine -upright) will first practice fiberoptic intubation with the iLarynx oriented in the supine position. Learning curves, global assessment score and checklist will then be obtained by a blinded examiner with the medical student using a real fiberoptic on a mannequin oriented in the UPRIGHT then SUPINE position. At the end of one week, The same medical student will then perform the intubation with the mannequin in both positions.

Upright - supine

Group D( upright - supine) will first practice fiberoptic intubation with the iLarynx oriented in the upright position. Learning curves, global assessment score and checklist will then be obtained by a blinded examiner with the medical student using a real fiberoptic on a mannequin oriented in the SUPINE then UPRIGHT position. At the end of one week, the same medical student will then perform the intubation with the mannequin in both positions.
