Title of the talk: Development of local antibiotic delivery system from fibrin gel to prevent bacterial biofilm graft infection

Abstract

Prosthetic vascular graft infection is one of the most serious complications after vascular surgery. Fibrin gel (FG) has many useful characteristics as biocompatibility, biodegradation, adhesion and haemostasis for development of local antibiotic delivery system. In this study, human plasma was collected from peripheral blood that was used to create fibrin gel by supplement ion Ca²⁺. Fibrin gel containing antibiotic was then evaluated in some characteristics such as surface structure, biodegradation, delivery antibiotic, cytotoxicity and prevention of bacterial biofilm in vitro. The results showed that fibrin gel was excellent material for extended delivery of antibiotic. Most importantly, fibrin gel containing antibiotic were not toxic for human fibroblast cells in vitro and inhibited growth of bacterial biofilm in vitro. This research as the first step for development of antibiotic delivery system for effective treatments for graft infection.
