Intraoperative management for patients during orthotopic lung transplantation may be performed without mechanical circulatory support, with veno-arterial extracorporeal membrane oxygenation (VA-ECMO), or cardiopulmonary bypass (CPB). For certain patients, an intraoperative conversion from VA-ECMO to CPB may be indicated. If a VA-ECMO patient requires CPB conversion, the previous model at our institution used two separate machines and was overall inefficient. The primary aim of this project was to develop a CPB pack modification to create a circuit that easily converts from VA-ECMO to CPB if indicated. The secondary aim was to create new supportive protocols and a comprehensive education and training curriculum for our large perfusion department to enhance patient safety. The new circuit was carefully designed and evaluated to minimize changes to the current CPB circuit while allowing for the safest configuration of VA-ECMO. A new protocol was designed with multi-disciplinary collaboration. A comprehensive education and training curriculum, as well as an objective competency assessment tool, were created. The circuit was subjectively evaluated by perfusionists and outscored our previous model in the areas of ease of setup, use, and CPB conversion. It received positive feedback from cardiothoracic surgeons and anesthesiologists as well. Lastly, it provided a financial benefit to our institution.
