ABSTRACT
Objective To investigate the effect of fibrin sealant cefazoline sodium implant on prevention and treatment of orthopaedic infection. Methods The fibrin sealant antibiotic implant was made by 10 ml (100 mg/ml) profibrin (Human) mixed with 2.0 g cefazoline sodium, after which 5 ml (200 PE/ml) prothrombin complex concentrate (Human) was added. A total of 24 female New Zealand white rabbits were recruited in the study and divided into three groups, ie, Group A that was implanted with the fibrin sealant antibiotic implant, Group B that was implanted with antibiotic and Group C that was as control. The model of bone infection was made by injecting 0.2 ml(1?10~6 CFU/ml) staphylococcus aureus into the bone hole in tibia of two legs. The histologic and radiologic bone changes were evaluated 2, 4 and 8 weeks after therapy. And in vitro release test was performed. Results There was not evidence of osteomyelitis in Group A, but the osteomyelitis was observed in Groups B and C. Concentration of cefazoline sodium about (1 043.94?0.20) ?g per piece was released from fibrin sealant cefazoline sodium implant within the first 24 hours by in vitro diffusion test but felt to (7.21?0.02) ?g per piece at the 35th day. Conclusion The fibrin sealant cefazoline sodium implant is simple to make and effective in preventing and treating orthopaedic infection as well as in improving repair of the bone defects.
