Objective comparison of animal training versus artificial simulation for initial cricothyroidotomy training

Area of Science:

• Medical Education
• Surgical Training
• Emergency Medicine

Background:

• Effective training for emergency procedures like cricothyroidotomy is crucial.
• Traditional animal models are often used, but ethical and practical concerns exist.
• Advancements in simulation technology offer potential alternatives for surgical skills training.

Purpose of the Study:

• To compare the effectiveness of initial cricothyroidotomy training using animal models versus artificial simulators.
• To objectively assess performance outcomes in novice trainees after both training modalities.

Main Methods:

• Volunteers without prior experience were randomized to train on either a pig model or an artificial simulator.
• Identical lectures and proficiency-based training were provided to all participants.
• Two weeks post-training, performance was evaluated on human cadavers, measuring time, incision size, accuracy, and success rate.

Main Results:

• No statistically significant differences were observed between the animal-trained and simulator-trained groups across all measured metrics.
• Success rates were 64% for animal training and 73% for simulator training (P=0.431).
• Accuracy of initial incision placement (93% vs 100%, P=0.452) and final tube placement (79% vs 88%, P=0.782) showed no significant difference.

Conclusions:

• Initial training for cricothyroidotomy using artificial simulators is as effective as using animal models.
• There is no objective benefit to using animal training for initial cricothyroidotomy instruction.
• Simulation technology provides a viable and comparable alternative for emergency procedure training.
