AbstractA 74-year-old man with ruptured thoracoabdominal aortic aneurysm was scheduled for open surgical repair under partial cardiopulmonary bypass. He had a history of diabetes mellitus and a concomitant renal dysfunction, requiring regular intermittent hemodialysis. To maintain electrolytes, acid base as well as water balance within adequate ranges, we planned to use continuous hemodiafiltration (CHDF) during the surgery because there was a high incidence of bolus transfusion to deal with massive bleeding in these surgeries. We increased fluid removal speed of ultrafiltration when blood components had to be infused rapidly. With these considerations, the patient did not develop fluid overload, hyperkalemia, or aggravation of acidosis. We did not administer anticoagulants into CHDF circuit because activated coagulation time was prolonged probably due to massive bleeding prior to the surgery. Heparin was administered just before the partial car diopulmonary bypass. There was no evidence for thromboembolic complications due to CHDF use. In conclusion, we successfully managed electrolytes as well as acid base balance, and hydration of a patient with chronic renal failure by using CHDF during open graft repair of ruptured thoracoabdominal aortic aneurysm.
