I am searching for studies which describe and examine sterile water for locking double lumen after hemodialysis ,but one study compared normal saline 0.9% with heparin. of course I attached some study that you can see guidelines for locking double lumen .
studies about the role of Sterile water can not prevention of thrombosis and blood stream infection is very limited.over ally it seems that combination approaches for examples Antimicrobial-impregnated catheters or usage of sodium citrate or heparin is better for lock of hemodialysis catheter
