A novel simulation model for tube thoracostomy

Area of Science:

• Medical Simulation
• Emergency Medicine Training
• Surgical Skills Development

Background:

• Tube thoracostomy is a critical emergency procedure requiring proficient skill.
• Existing simulation models can be prohibitively expensive for widespread training.
• Need for accessible and realistic training tools in emergency medicine.

Purpose of the Study:

• To develop a simple, reproducible, and cost-effective simulation model for tube thoracostomy.
• To provide an alternative to expensive commercial training mannequins.
• To facilitate hands-on learning of key anatomical landmarks and procedural steps.

Main Methods:

• Utilized pork rib slabs with intercostal muscles to mimic human anatomy.
• Constructed a simulator using a plastic hamper, pillow (for lung simulation), and common materials.
• Secured rib slabs and wrapped the complex to simulate skin and subcutaneous tissues.

Main Results:

• The model's initial cost is approximately $50, significantly lower than commercial alternatives ($1,000-$3,000).
• Cost per attempt is approximately $1.78, compared to $4.00 for the cheapest commercial system.
• The model is easily reproducible and utilizes commonly available materials.

Conclusions:

• A porcine-based simulation model for tube thoracostomy is feasible, realistic, and inexpensive.
• This model can be used for training in tube thoracostomy, thoracentesis, and thoracotomy.
• Further research is needed to validate its educational efficacy compared to commercial models.
