Comparison Between Vancomycin Lock and Taurolock Solution for the Prevention of Catheter- related Infections in Hemodialysis Patients, A Multicenter Study.

INTRODUCTION

Central venous catheters, frequently used in patients undergoing hemodialysis, place the patients at high risk of catheter-related infections. Therefore, it is essential to select the optimal prevention protocol for these infections. This study aims to compare the efficacy of the Taurolock solution and antibiotic lock in preventing tunneled catheter (permcath) related infections.

METHODS

This multicenter study was conducted between June 2020 and July 2021 on 86 hemodialysis patients with a central venous catheter from four dialysis centers in Tehran, Iran. The patients were randomly assigned into two groups. The first group received Taurolock, and the second group received antibiotic lock (a combination of vancomycin and heparin) at the end of each dialysis session. Peripheral blood and catheter blood samples were collected once before the intervention and monthly thereafter, for up to six months, and blood culture performed for detection of various bacterial strains.

RESULTS

The findings showed no significant difference in the infection rate (positive peripheral blood or catheter cultures) between the Taurolock and vancomycin groups (P > .05). Additionally, there was no significant difference in the duration of catheter implantation in individuals with positive and negative cultures (P > .05). Furthermore, no significant correlation was found between comorbidities and catheter-related infection in patients of the two groups (P > .05).

CONCLUSION

There was no significant difference between the two groups in the rate of catheter-related infection. Therefore, vancomycin lock solutions can be good alternatives to Taurolock solution for preventing catheter-related infections.  DOI: 10.52547/ijkd.7615.
