Teaching Emergency Surgical Skills for Trauma Resuscitation-Mechanical Simulator versus Animal Model

Abstract EN

Background.

Traditionally, surgical skills in trauma resuscitation have been taught using animal models in the advanced trauma life support (ATLS) course.

We compare one mechanical model (TraumaMan simulator) as an alternative teaching tool for these skills.

Method.

Eighteen providers and 14 instructors performed four surgical procedures on TraumaMan and compared educational effectiveness with the porcine model.

Evaluation was conducted (Likert system 1: very poor to 5: excellent).

The participants indicated if TraumaMan was a suitable (scale 1: not suitable to 4: excellent) ATLS teaching model considering cost, animal ethics concerns, and other factors.

Comments were solicited for both models.

Results.

Overall ratings for educational effectiveness of the 4 skills ranged from 3.58 to 4.36 for the porcine and 3.48 to 4.29 for the TraumaMan model.

TraumaMan suitability was rated 3-4 (mean 3.38) by 84% participants.

TraumaMan as a substitute for the porcine model was recommended by 85% participants.

With no ethical or cost concerns, 44% students and 71% instructors preferred TraumaMan.

Considering all factors, TraumaMan was preferred by 78% students and 93% instructors.

Conclusions.

TraumaMan is a suitable alternative to the porcine model and considering all factors it may be the preferred method for teaching ATLS emergency trauma surgical skills.
