Successful Unconventional Treatment of Serratia Marcescens Exit-Site Infection in a Central Venous Catheter for Hemodialysis: A Case Report.

Abstract

Introduction. Central Catheter-related infections and biofilm formation are significant issues in the context of nosocomial infections that increase resistance to conventional therapies. Methodology. This case report describes an unconventional treatment for a Serratia Marcescens Central Venous Catheter infection in a hemodialysis patient through the combination of polyguanide and betaine. Clinical evaluations were conducted using the Visual Exit-Site Score and culture swabs. Results. After the first four treatment sessions there was a significant reduction in redness and pain (VES=1); the culture swab at the end of treatment was negative. Conclusions. The results of this case report encourage further research on the effectiveness of non-antibiotic treatments.
