Learning fibreoptic intubation with a virtual computer program transfers to 'hands on' improvement.

Area of Science:

• Medical Education
• Anesthesiology
• Simulation Training

Background:

• Fibreoptic intubation is a critical anesthesiology skill that presents significant learning challenges in clinical settings.
• Traditional teaching methods for fibreoptic intubation may not adequately prepare all trainees.
• Developing effective adjuncts for skill acquisition is crucial for improving patient safety.

Purpose of the Study:

• To evaluate the efficacy of virtual fibreoptic intubation (VFI) software as a supplementary tool for traditional fibreoptic intubation teaching.
• To compare the learning outcomes of students using VFI software versus conventional instruction.

Main Methods:

• Forty-two undergraduate medical students were randomized into a control group (traditional lecture) and a VFI group (lecture plus VFI software self-training).
• The VFI group utilized CD-ROM software for self-directed practice on virtual patient models.
• Skill acquisition was assessed two weeks later through a blinded evaluation of manikin-based fibreoptic intubation performance.

Main Results:

• The VFI group demonstrated a significantly higher fibreoptic intubation success rate (81%) compared to the control group (52%, P < 0.05).
• Fewer esophageal intubations occurred in the VFI group (1/4 failures) versus the control group (9/10 failures).
• While the VFI group experienced more time-related failures (>4 min), overall procedural skills tended to be better.

Conclusions:

• Self-training with virtual fibreoptic intubation software can enhance the acquisition of fibreoptic intubation skills.
• VFI software shows promise as an effective adjunct to traditional anesthesiology training.
• Simulation-based training may improve the proficiency and success rates of novice endoscopists.
