A method of performing veno-arterial modified ultrafiltration is described that utilizes conventional blood flow through the aortic and venous cannulae. A dual-pump blood cardioplegia console is adapted to aspirate blood from the cardiopulmonary bypass venous line. The blood is ultrafiltered, sent through the cardioplegia heat exchanger, and returned to the aorta via the cardioplegia needle.
Veno-arterial modified ultrafiltration has produced no visual evidence of air entrainment in the cardiopulmonary arterial line. This method allows the immediate resumption of cardiopulmonary bypass without the need for the surgeon to recannulate or alter tubing. Thirty-five children underwent veno-arterial modified ultrafiltration; the results show significant increases in postoperative hematocrit, early extubation, and improved rheology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
