Development of a High-Fidelity Simulator for Teaching Chorionic Villus Sampling

      Abstract

      Objective

      The objective of this study was to develop a synthetic high-fidelity simulator for teaching chorionic villus sampling.

      Methods

      Working with a medical sculptor, the authors developed a simulator, constructed from various synthetic rubber materials, of a gravid female pelvis, including the vulva, vagina, cervix, and a 13-week-sized uterus with a gestational sac.

      Results

      This simulator is high fidelity and durable, and it does not require any organic materials. Maternal-fetal medicine trainees valued this educational tool.

      Conclusion

      This novel, high-fidelity simulator is an additional tool for educators involved in teaching chorionic villus sampling.

      Résumé

      Objectif

      Cette étude avait pour but de concevoir un simulateur synthétique de haute fidélité aux fins d'enseignement du prélèvement de villosités choriales.

      Méthodologie

      Les auteurs ont conçu, avec l'aide d'un sculpteur médical, un simulateur, construit à partir de divers matériaux en caoutchouc synthétique, représentant le pelvis d'une femme enceinte; la vulve, le vagin, le col utérin et un utérus contenant un sac gestationnel de 13 semaines y sont notamment reproduits.

      Résultats

      Durable et de haute fidélité, ce simulateur n'a besoin d'aucune matière biologique. Cet outil éducatif a d'ailleurs été apprécié par les stagiaires en médecine fœto-maternelle.

      Conclusion

      Ce simulateur de haute fidélité novateur est un outil de plus à l'arsenal des éducateurs chargés d'enseigner le prélèvement de villosités choriales.
