[Regional anticoagulation with sodium citrate: chronic utilization in the hemodialysis patient].

We used an alternative technique for regional citrate anticoagulation (citrate 0.48 Mol; bicarbonate containing dialysate with Ca 1.75 Mmol) in three patients at chronic risk of bleeding and for a mean follow-up period of ten months. No bleeding recurrence was observed nor any complication related to citrate. Hemoglobin and hematocrit rose without transfusions. Serum bicarbonate increased during the first four months of treatment. No significant change was observed in serum calcium nor serum sodium concentration.
