Abstract

Patient demographics for elective cardiovascular surgery have shifted toward older patients with more profound disease states. Cardiopulmonary bypass is complicated when the patient presents with end stage renal disease. Hemodialysis during cardiopulmonary bypass has been successfully employed to reduce the postoperative sequelae associated with cardiopulmonary bypass. A patient with end stage renal disease who presented for coronary artery bypass grafting serves as the subject of this case report. Utilizing a modified technique previously described by Wiggins and Dearing, we describe successful intraoperative use of hemodialysis during cardiopulmonary bypass. Our experience suggests that hemodialysis during cardiopulmonary bypass is an effective alternative to ultrafiltration and may prolong the time interval for resumption of postoperative dialysis regimens.
