简要总结
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.
详细描述
Following IRB approval, written consent to participate in the study will be obtained from medical students
Phase one :
Forty medical students, novices in fiberoptic intubation use will be recruited and randomly assigned into one of two groups:
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.
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 SUPINEposition.At the end of one week, the same medical student will then perform the intubation with the mannequin in both positions.
