- W3170052187 abstract "Abstract Background and Aims Infections and thrombosis of central venous catheter (CVC) in hemodialysis patients are the major causes of catheter loss resulting in hospitalization and increased costs. Interdyalitic catheter lock solutions, usually heparin, avoid these complications. Among the many, sodium bicarbonate has been proved as effective and safe catheter lock solution due to its antimicrobial and antithrombotic properties. The aim of this study was to compare the efficacy of two different CVC lock solution: sodium heparin versus sodium bicarbonate, to prevent catheter–related thrombosis and infection in hemodialysis patients Method They were enrolled, in a 12 months case-control study, 17 hemodialysis patients with tunneled hig-flux CVC (femoral or internal jugular). Each patient was evaluated in its common treatment for CVC dysfunction (Qb, CVC that works in reverse branches during the hemodialysis session, use of urokinase or extra lock with sodium heparin or 4% citrate) and infection (WBC count, C reactive protein -CRP, bloodstream culture, exit-site infection -ESI) during standard sodium heparin CVC lock solution (hep-lock), for the first 6 months, and then, during sodium bicarbonate lock solution (10 mEq/10 ml, bic-lock) for following 6 months. aPTT, PLT, Hct and albumin are also montly evaluated. Type and anticoagulant dose during hemodialysis sessions were unchanged over the study as well as any antiplatelet/anticogulant home therapy. Results Fifteen patients on 17 completed the study and the main results are reported in table 1. There were no significant differences between patients on demographics and number of catheter days treatments for both study periods. The blood flow was similar in either study phases and stable during the hemodialysis sessions (Qb 225±13 ml/m’ at 2-hours vs 225±15 ml/min at start of dialysis), even the use of reverse branches was similar. Hep-lock showed a lower usage of extra lock drug in comparison with Bic-lock (0,4% vs 3,1%, p<0,05), data confirmed also for Urokinase (1,9% vs 3,4%, p=0,274). None bloodstream are registred while ESI and WBC count show no significant differences between two study periods. No HD catheter was loss during the study due to thrombosis or infection. Finally, Hct, CRP and Albumin was found slightly lower on Bic-lock phase. Conclusion There is no CVC ideal lock solution and although sodium bicarbonate is inexpensive and readily avalaible our data shows better CVC performances with sodium heparin." @default.
