Clinical Trial Summary

This is a randomized, double blinded, prospective, multicenter, clinical trial of the use of Heparin versus Gentamicin as a pos-dialysis catheter lock solution.

Description:

The study is a randomized, double blinded, prospective, multicenter, clinical trial. All patients requiring vascular access with a tunneled central venous catheter for hemodialysis are eligible for enrollment. Patients will be randomized to receive either Heparin 1,000 U/ml in a volume sufficient to fill the catheter length in both ports or to receive 4% Sodium Citrate with Gentamicin 320 mcg/mL in a volume sufficient to fill the catheter length in both ports.We hypothesize that the device related infection rate in the Citrate/Gentamicin group will be less than the heparin arm.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Rate of Device-related Bacteremia	Positive blood cultures in a patient whose vascular access is a central venous catheter without another obvious source of infection	5 years
Secondary	Rate of Catheter Clotting Measured as Requirement for tPA Usage to Maintain Blood Flow	The rate of thrombolytic agent use required to maintain blood flow adequate for dialysis was used as an objective measure of clinically significant catheter clotting.	5 years
