Videotape feedback significantly improved medical students' perception of their laryngoscopy skills. Reviewing their performance revealed overestimations in head extension and underestimations in procedure duration.

Area of Science:

  • Medical Education
  • Anesthesiology
  • Simulation Training

Background:

  • Laryngoscopy is a critical skill for medical students.
  • Objective feedback is essential for skill acquisition.
  • Self-perception may not accurately reflect performance.

Purpose of the Study:

  • To determine if videotape feedback offers unique educational insights for students learning laryngoscopy.
  • To assess the impact of video feedback on self-assessment of laryngoscopy performance.

Main Methods:

  • Twenty-six medical students were videotaped performing laryngoscopy.
  • Students completed questionnaires on positioning, head movement, neck flexion/extension, and duration before and after video review.
  • Perceived distraction and educational value of the video feedback were assessed.

Main Results:

  • Perceived inadequacy of head and neck positioning increased from 4% to 38% after video review (P=0.029).
  • Students overestimated head extension (34.0° vs. 21.5°, P=0.003) and underestimated procedure duration (55s vs. 75s, P=0.024).
  • Despite some feeling distracted, all students found the video feedback educationally valuable.

Conclusions:

  • Videotape feedback alters students' self-perception of laryngoscopy performance.
  • It highlights discrepancies in assessing head extension and procedure duration.
  • Video feedback is a valuable tool for improving laryngoscopy training.
