This study presents a low-cost, handmade phantom for practicing nerve blocks using fluoroscopic guidance. The inexpensive simulation tool offers basic training for regional anesthesia procedures.

Area of Science:

  • Medical Simulation
  • Anesthesiology
  • Radiology

Background:

  • Commercially available regional anesthesia manikins with phantom skeletal structures are expensive.
  • There is a need for cost-effective training tools for nerve block procedures.

Purpose of the Study:

  • To introduce a handmade, low-cost phantom for training nerve blocks with fluoroscopic guidance.
  • To provide an accessible simulation alternative for regional anesthesia education.

Main Methods:

  • The phantom was constructed using artificial bone models simulating lumbar vertebrae and intervertebral disks.
  • The bone models were covered with 5-7 layers of self-adhesive sponge to mimic tissue resistance.
  • Posteriorly, mobility between sponge layers was preserved to allow needle deflection practice.

Main Results:

  • The handmade phantom provides a functional simulation for practicing needle manipulation and redirection.
  • The low-cost design makes it an accessible option for basic training in nerve block techniques.

Conclusions:

  • This inexpensive phantom, despite potential limitations in radiographic fidelity, is suitable for fundamental training in fluoroscopic-guided nerve blocks.
  • The developed phantom serves as a valuable, budget-friendly resource for regional anesthesia simulation.
