This study presents a low-cost, anatomically accurate simulator for flexible fiberoptic bronchoscopy training in intensive care units. The DIY simulator, costing only euro16, allows practice on ventilated patients, overcoming cost and ethical barriers to resident training.

Area of Science:

  • Medical Simulation
  • Respiratory Medicine
  • Medical Education Technology

Background:

  • Flexible fiberoptic bronchoscopy is crucial for intensive care unit (ICU) patient management.
  • Residency training in bronchoscopy faces challenges due to technical, ethical, and cost barriers associated with commercial simulators.

Purpose of the Study:

  • To develop and evaluate a low-cost anatomical simulator for acquiring and maintaining flexible fiberoptic bronchoscopy skills in ventilated patients.
  • To provide an accessible training tool for medical professionals, especially in resource-limited settings.

Main Methods:

  • Constructed a bronchial tree scaffold using 1.5 mm iron wire.
  • Created the anatomical model using glazier's putty, layered with newspaper strips soaked in water and vinilic glue.

  • Assembled, painted, and fitted the dried model with an endotracheal tube, achieving a final cost of euro16.

    • Main Results:

    • The simulator is real-scale, anatomically accurate, and provides realistic endoscopic views comparable to patients.
    • All bronchial segments are explorable and identifiable via both endoscopic and external visualization.
    • The simulator effectively facilitates practice for bronchoscopy on ventilated patients.

    Conclusions:

    • This low-cost simulator is a valuable and accessible tool for practicing flexible fiberoptic bronchoscopy skills.
    • It addresses the limitations of traditional training methods by offering a cost-effective and practical alternative.
    • The simulator is particularly beneficial for hospitals with limited resources for medical training.
