We assessed catheters for catheter dysfunction and infection. Both nontunneled dialysis catheters (NTDC) and tunneled dialysis catheters (TDC) were evaluated. We studied 250 catheters and 139 met inclusion criteria: 90 catheters in the ACD group and 49 in the heparin group. ACD had superior outcomes for NTDC; event rate was 0.052 for NTDC ⁄ ACD and 0.125 for NTDC ⁄ heparin (p = 0.032). There was no difference for TDC. Univariate (odds ratio [OR]: 1.88, confidence interval [CI]: 0.931, 3.82) and multivariate (OR: 1.35, CI: 0.64, 2.87) analyses demonstrated a trend toward increased odds of event with heparin. Catheter lock with 2.2% ACD has lower risk of catheter dysfunction as compared with that of 5000 U ⁄ ml heparin in the shortterm inpatient setting in NTDC and similar risk in TDC.A Randomized Controlled Trial of Comparative Efficacy between Sodium Bicarbonate and Heparin as A Locking Solution for Tunneled Central Venous Catheters Among Patients Requiring Maintenance HemodialysisCanadian journal of kidney health and disease, 2021Background: Sodium bicarbonate (NaHCO 3) is one of the promising solutions that has good safety profile and theoretical advantages regarding antimicrobial and antithrombotic properties but there are still limited reports. Objective: To compare the efficacy in lowering rate of catheter loss due to catheter-related thrombosis (CRT) or catheterrelated blood stream infection (CRBSI) between sodium bicarbonate and heparin lock in prevalent chronic hemodialysis (HD) patients. Design: A multicenter, randomized, open-label study Setting: In a developing country, Thailand Patients: Chronic HD patients with tunneled central venous catheter Measurements: Catheter loss rate, rate of catheter-related blood stream infection, catheter-related thrombosis, and exit site or tunnel infection Methods: The prospective multicenter randomized controlled trial was conducted, we randomly assigned 118 patients undergoing HD with tunneled central venous catheter to receive a catheter locking solution of sodium bicarbonate or heparin. The primary outcome was a catheter loss rate due to CRT or CRBSI, while the secondary outcome was a composite outcome of CRT, CRBSI, or exit site/tunnel infection (ESI/TI). Results: The present study was stopped early due to an excess of catheter-related thrombosis in the sodium bicarbonate group. From the first 6 weeks of follow-up, there were no catheter losses due to CRT or CRBSI in both groups. The sodium bicarbonate group had a significantly higher rate of the secondary composite outcomes and this was entirely caused by CRT with the median time to thrombosis of 23.6 days. Every CRT event could be successfully rescued by using a single dose of recombinant tissue plasminogen activator (rt-PA). Limitations: Short follow-up period. Conclusions: In prevalent HD patients with tunneled CVCs, use of a sodium bicarbonate locking solution for prevention of CRT is inferior to heparin and is associated with a high rate of catheter-related thrombosis. Trial registration: The study was registered with the Thai Clinical Trials Registry TCTR 20200610003 Abrégé Contexte: Le bicarbonate de sodium (NaHCO 3) figure parmi les solutions prometteuses présentant un bon profil de tolérance et des bienfaits théoriques en matière de propriétés antimicrobiennes et antithrombotiques.
