Introduction: Emergency thoracostomy is applied in life-threatening situations. Simulation plays a pivotal role in training in invasive techniques used mainly in stressful situations. Currently available commercial simulation models for thoracostomy have various drawbacks.
Methods: We designed a thoracostomy phantom from discarded hospital materials and pigskin with underlying flesh. The phantom can be used alone for developing technical skills or mounted on an actor in simulation scenarios. Medical students, intensive care unit (ICU) and emergency department teams, and thoracostomy experts evaluated its technical fidelity and usefulness for achieving learning objectives in workshops.
Results: The materials used to construct the phantom cost €47. A total of 12 experts in chest-tube placement and 73 workshop participants (12 ICU physicians and nurses, 20 emergency physicians and nurses, and 41 fourth-year medical students) evaluated the model. All groups rated the model's usefulness and the sensation of perforating the pleura highly. Experts rated the air release after pleura perforation lower than other groups. Lung reexpansion was the lowest rated item in all groups. Ratings of the appearance and feel of the model correlated strongly among all groups and experts. The ICU professionals rated the resistance encountered in introducing the chest drain lower than the other groups.
Conclusions: This low-cost, reusable, transportable, and highly realistic model is an attractive alternative to commercial models for training in chest-tube insertion skills.
