Modified Ultrafiltration in Pediatric Cardiopulmonary Bypass

The Journal of ExtraCorporeal Technology, 1994
Cardiopulmonary bypass in children is frequently associated with increased capillary permeability resulting in increased total body water, tissue edema, and organ dysfunction. Hemodilution also occurs and may require transfusion. Modified ultrafiltration utilizes the extracorporeal circuit to perform hemofiltration of the patient immediately following ...
