Abstract
Background
Simulation provides a safe learning environment where high-stakes, low-frequency procedures
can be practiced without the fear of being unsuccessful or causing harm. Emergency
department thoracotomy (EDT) is one such procedure. Realistic thoracotomy models are
expensive and not readily available.
Objective
Our objective is to describe a cost-effective, realistic, reproducible, and reusable
thoracotomy model for simulation training.
Methods
We modified a commercially available clothes mannequin torso to expose the chest and
abdominal cavity. A plastic skeleton composed of a spinal cord and ribs was placed
inside the torso. Tubing was used to simulate the aorta and esophagus; both tubes
were secured to the distal spine with zip ties. Commercially available lungs and heart
were placed inside the chest cavity. A small rubber ball simulated the left lung to
be able to maneuver the lung. The heart was covered with plastic wrap to simulate
the pericardium. Thick tape was used to simulate the pleural cavity. Yoga mats were
used to simulate the intercostal muscles, subcutaneous tissue, and skin.
Results
This model was tested with Emergency Medicine (EM) residents during a simulation session.
A voluntary survey was available for residents to provide feedback. Survey results
confirmed that the model provided valuable education, with overall positive feedback.
Conclusion
This EDT model provides a valuable teaching opportunity to EM residents who otherwise
might not have the opportunity to perform this procedure. Residents agreed that the
model improved their confidence and is an effective method in providing the opportunity
to practice this low-frequency, high-stakes procedure.
