Prevention of Central Line-Associated Bloodstream Infection by Poly (Hexamethylene Biguanide) Coatings: A Systematic Review

Journal of Kerman University of Medical Sciences
Background: The significance of central line-associated bloodstream infection (CLABSI) is that it increases morbidity, mortality, and treatment costs. The incidence of infections is reduced by the use of antibiotic-impregnated dressings at the central catheter insertion site. In this context, polyhexamethylene biguanide (PHMB)-containing dressings have

Incorporation of biguanide compounds into poly(GL)-b-poly(GL-co-TMC-co-CL)-b-poly(GL) monofilament surgical sutures [PDF]

, 2017
A new biodegradable coating was developed for bioabsorbable monofilament sutures. Specifically, a random copolymer having 35 wt-% and 65 wt-% of lactide and trimethylene carbonate units showed appropriate flexibility, stickiness and degradation rate, as ...

The antimicrobial polymer PHMB enters cells and selectively condenses bacterial chromosomes [PDF]

, 2016
To combat infection and antimicrobial resistance, it is helpful to elucidate drug mechanism(s) of action. Here we examined how the widely used antimicrobial polyhexamethylene biguanide (PHMB) kills bacteria selectively over host cells.

Poly(hexamethylene biguanide) immobilized non-absorbable and antimicrobial PET fiber for surgical suture applications: synthesis, characterization and in vitro cytocompatibility assessment

Uluslararası Muhendislik Arastirma ve Gelistirme Dergisi
Surgical sutures are widely utilized medical devices for the purpose of closing wounds after surgical interventions. During surgical procedures, sutures can come into contact with microorganisms in the surrounding environment, leading to the development of bacterial biofilms and subsequent surgical site infections (SSI).
