The chicken, turkey, and plastic bone models offer variable simulation for intraosseous (IO) procedures in children. The pork rib model performed poorly, indicating a need for age-appropriate models in IO research and training.

Area of Science:

  • Medical Simulation
  • Pediatric Emergency Medicine
  • Anatomical Modeling

Background:

  • Intraosseous (IO) access is a critical procedure in pediatric emergency care.
  • Effective simulation models are essential for training healthcare providers in IO techniques.
  • Current simulation models vary in their ability to replicate the anatomical and physical properties of pediatric bones.

Purpose of the Study:

  • To evaluate and compare the efficacy of different bone models in simulating the intraosseous (IO) procedure in pediatric patients.
  • To identify the most suitable bone models for training and research in pediatric IO access.

Main Methods:

  • Forty experienced emergency and critical care physicians evaluated five IO bone models: plastic leg, turkey femur/thigh, turkey tibia, chicken femur/thigh, and pork rib.

  • Participants rated model similarity to pediatric anatomy and bone hardness across various age groups.
  • Mean scores were calculated to determine the best-performing simulation models.

    • Main Results:

    • The chicken, turkey, and plastic models received similar, acceptable mean scores (3.2-3.3).
    • The pork rib model demonstrated significantly poorer performance (mean score 4.4) across all age groups.
    • Most models exhibited issues with perceived bone hardness (too hard or too soft), except for the pork rib which was predominantly too hard.

    Conclusions:

    • Age-appropriate bone models are crucial for effective intraosseous (IO) research and teaching.
    • Chicken, turkey, and plastic models show variability but are generally preferred over pork rib models for pediatric IO simulation.
    • Further refinement of simulation models is needed to accurately replicate bone characteristics across pediatric age ranges.
