[Regional anticoagulation with citrate in hemodialysis in patients with a high risk for hemorrhage].

During haemodialysis in the patient at high risk for bleeding, heparin cannot be safely used to prevent clotting in the dialysis assembly. Among numerous procedures proposed to reduce the risk for bleeding, Pinnick et al. (N Engl J Med, 308: 258, 1983) proposed the use of citrate as the sole anticoagulant.
