Bicarbonate vs Heparin Catheter Lock in Chronic Hemodialysis Patients

Summary

Prospective clinical trial to evaluate the efficacy of catheter lock with bicarbonate vs heparin in chronic hemodialysis patients. Two groups will be created, sodium bicarbonate lock group (experimental group) and heparin lock group (control group). Catheter pressures, flow, patency and infection outcomes will be compare between groups at different time points (30, 60 and 90 days).
