Experimental study of antimicrobial polymeric composition with hemostatic effectin treatment of implant associated infection

Introduction Management of infection associated with surgical implants comprise local application of antimicrobial agents. The purpose of the in vivo experimental study was identification of an optimal antimicrobial polymeric composition with hemostatic effect for local wound application and assessment of its influence on clinical and morphological changes in implant-associated infection caused by staphylococcus in rabbit femur. Materials and methods A composition exhibiting minimal bleeding time was identified in the first experiment using six experimental samples with different concentration of tranexamic acid (TXA) and polyvinylpyrrolidone (PVP) implanted in the soft tissue wound of the rat liver (n = 18). Peri-implant infection caused by staphylococcus was simulated in the rabbit femur in the second experiment. Infected wire was implanted in the intramedullary canal of control animals (n = 9). The wire was steeped in gentamicin-containing sample selected in the first experiment before it was used for experimental animals (n = 9)...
