Yogaman: An Inexpensive, Anatomically-detailed Chest Tube Placement Trainer


Introduction: Opportunities for chest tube placement in emergency medicine training programs have decreased, making competence development and maintenance with live patients problematic. Available trainers are expensive and may require costly maintenance.

Methods: We constructed an anatomically-detailed model using a Halloween skeleton thorax, dress form torso, and yoga mat. Participants in a trial session completed a survey regarding either their comfort with chest tube placement before and after the session or the realism of Yogaman vs. cadaver lab, depending on whether they had placed <10 or 10 or more chest tubes in live patients.

Results: Inexperienced providers reported an improvement in comfort after working with Yogaman, (comfort before 47 millimeters [mm] [interquartile ratio {IQR}, 20-53 mm]; comfort after 75 mm [IQR, 39-80 mm], p=0.01). Experienced providers rated realism of Yogaman and cadaver lab similarly (Yogaman 79 mm [IQR, 74-83 mm]; cadaver lab 78 mm [IQR, 76-89 mm], p=0.67). All evaluators either agreed or strongly agreed that Yogaman was useful for teaching chest tube placement in a residency program.

Conclusion: Our chest tube trainer allowed for landmark identification, tissue dissection, pleura puncture, lung palpation, and tube securing. It improved comfort of inexperienced providers and was rated similarly to cadaver lab in realism by experienced providers. It is easily reusable and, at $198, costs a fraction of the price of available commercial trainers.
