Development and testing of a low cost simulation manikin for extracorporeal cardiopulmonary resuscitation (ECPR) using 3-dimensional printing.

BACKGROUND: There has been an explosive growth of ECPR within new and established ECMO programs worldwide with the concomitant need for simulation trainers. However, current commercially available ECMO simulation models are expensive and lack many standard cardiorespiratory resuscitative (CPR) features.

OBJECTIVE: To use 3-dimensional (3D) printing to develop a training manikin for comprehensive ECPR simulation.

METHODS: A standard commercially available CPR manikin with airway model was used as the base model for modification. An inexpensive 3D printer was used to print a modular plastic pelvis. A medical silicone gel incorporated silicone femoral vasculature component was manufactured with connection to a gravity fed vascular system.

RESULTS: The resulting modified manikin included the modular in-house designed ECMO cannulation and vascular structures wedded to the commercially available airway and CPR components. In simulation exercise involving first responders, paramedics, and emergency and critical care physicians, the model was reported as realistic with ultrasound views, cannulation, and resuscitative components functional. The entire cost for development of the ECMO component was estimated at $2000 Australian dollars AUD, including the printer purchase and supplies. Future reuse of components is estimated to cost less than $5 AUD per simulation run.

CONCLUSIONS: A novel in-house modified manikin for ECPR was developed that was cost-efficient and realistic to use from first response through to establishment of ECMO circulation.
