ABSTRACT
Heparinization during hemodialysis may cause severe bleeding complications in patients with high bleeding risk. Heparin-free hemodialyses (n = 208) were performed in 46 unselected patients with high bleeding risk after kidney transplantation (n = 25), after major surgery (n = 10), and with bleeding disorders (n = 11). Dialyser and blood lines were primed without heparin. In addition to the established measures (high blood flow, intermittent rinsing), system clotting was prevented by prophylactically changing the dialyser and blood lines in 107 of 208 dialyses (52 percent). Total system clotting with blood loss ranging from 100 to 250 ml occurred in six cases (3 percent). Mean hemodialysis time (+/- SD) was 4.1 hours (+/- 0.4), rising volume of the extracorporeal system 1.4 liters/hour (+/- 0.6), blood flow 244 ml/min (+/- 38), clotting time 12 min (+/- 4), and weight loss 2.5 kg (+/- 1.5). Mean hemodialysis creatinine clearance was 110 ml/min (+/- 34) and BUN clearance 138 ml/min (+/- 48). Heparin-free hemodialysis with prophylactic change of system is thus a safe and practical method of treatment for patients at high bleeding risk, but it is less effective, more expensive and the patient requires closer care.
