Area of Science:

  • Veterinary Medicine
  • Surgical Education
  • Medical Simulation

Background:

  • Rising costs and public opinion necessitate alternative veterinary training methods.
  • Traditional methods, including live animal use, face ethical and financial challenges.
  • Development of innovative teaching tools is crucial for modern veterinary surgical education.

Purpose of the Study:

  • To evaluate the effectiveness of a novel fluid hemostasis model for teaching veterinary surgical skills.
  • To compare the hemostasis model's efficacy against traditional live animal training for vessel ligation and division.
  • To assess veterinary students' perceptions of inanimate models in surgical training.

Main Methods:

  • A fluid hemostasis model simulating peripheral vascular structures was developed.

Related Experiment Videos

  • Forty veterinary students were divided into two groups for comparative training.
  • Psychomotor skills were assessed using inanimate models before and after practice sessions on either the hemostasis model or live dogs.

    • Main Results:

    • The hemostasis model demonstrated comparable effectiveness to live animals in teaching basic blood vessel ligation skills.
    • Objective evaluation of psychomotor skills showed no significant difference between the two training methods.
    • Student attitudes towards using inanimate models for surgical training significantly improved.

    Conclusions:

    • The fluid hemostasis model is a viable and effective alternative to live animals for teaching fundamental vascular surgical techniques.
    • Inanimate models, when properly designed, can significantly enhance veterinary surgical training without compromising skill acquisition.
    • This study supports the integration of simulation-based training into veterinary medical curricula.
