Assessment of the effect of suture material on the bacterial contamination of trachea

Abstract

The work is devoted to assessment of bacterial contamination of trachea after circular resection with the following tracheo-tracheal anastomosis in Wistar rats. The formation of tracheo-tracheal anastomosis with the use of a monofilament, not resorptive suture material after circular resection of trachea is accompanied by the microbial growth in 83.4% of cases. The major microorganisms are conditionally pathogenic – Citrobacter freundii, Staphilococcus epidermidis, Proteus rettgeri, Escherichiae coli, they occur in 71% of cases. Pathogenic microorganisms Staphilococcus aureus, Candida fungi appeared only in microbial associations and were found in 12.5% of cases. No microbial growth was observed in 16.6%.
