چکیده

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.

Modified ultrafiltration after cardiopulmonary bypass in pediatric cardiac surgery.

BACKGROUND Cardiopulmonary bypass in children results in considerable water retention, especially in neonates and small infants. Dilution of plasma proteins increases water loss into the extravascular compartments. Excessive total body water may prolong ventilatory support and may contribute to a prolongation of intensive care convalescence. After discontinuation of cardiopulmonary bypass, modi...

The Effect of Zero Balance Ultrafiltration of Priming Blood on Clinical Outcomes of Infants Undergo Cardiopulmonary Bypass

Introduction: Pediatric Cardiopulmonary Bypass (CPB) circuit invariably requires priming with Packed Red Blood Cells (PRBCs). Metabolic composition of stored PRBCs is unphysiological. Commencement of PRBC primed CPB leads to rapid transfusion of massive metabolic load. This predisposes pediatric patients to the risk of complications such as electrolyte disturbances, citrate toxicity, acidosis a...
