Abstract

Background: Establishment of cardiopulmonary bypass facilities is indispensable as an initial education in cardiac surgery. However, education in clinical setting has been accompanied by ethical problems. Therefore, training on cardiopulmonary bypass facilities in the cardiac surgery field requires the use of simulation. However, an appropriate simulator is not available presently in Japan.

Methods: Mimic blood vessels that can tolerate blood pressure and has flexibility for cannulation, which are required for a cardiopulmonary bypass simulator, were constructed. The necessary and sufficient mimic blood vessels were constructed using a three-layer silicone material for the arterial layer and a two-layer silicone material for the venous layer. A PIT simulator (manufactured by JMS) was connected to the aorta and vena cava of the mimic blood vessels as a CPB simulator.

Results: Practical blood flow by heartbeat, stitching the aorta/vena cava, and cannulation were simulated using a PIT CPB simulator. This system was connected to cardiopulmonary bypass facilities, similar to clinical practice. Simulation of cross-clamping of the aorta, injection of cardioplegia at the base, and heart arrest could be reproduced. A process from cancellation of the aorta cross-clamping to liberation of the cardiopulmonary bypass and cannulation could be reproduced as if in a clinical setting.

Conclusion: Practical simulation training from establishment to liberation of a cardiopulmonary
