Bacterial contamination of the trachea after circular resection, depending on the type of suture material

Rationale: The choice of suture material is an important factor in the formation of tracheal anastomoses. This study compares the use of synthetic absorbable suture with that of synthetic nonabsorbable suture for construction of cervical tracheal anastomoses in the rats. The work is devoted to the evaluation of bacterial tracheal contamination after performing a circular resection followed by the imposition of tracheal anastomoses in Wistar rats using a different suture material.Objective: The work was performed using 48 Wistar rats. To study the contamination of lumen and tracheal tissue after performing its circular resection, depending on the type of suture material.Results: The microflora of the trachea was analyzed depending on the type of suture material.Conclusion: The type of suture material does not affect the frequency of microbial associations. The main microorganisms are conditionally pathogenic - Citrobacter freudii, Staphilococcus epidermidis, Proteus rettgeri, escherichiae coli. The use of a non-absorbable suture results in an increase in microflora of 83.4%, while the use of absorbable suture material in 62.5%. In this regard, with surgical interventions to restore the lumen of the trachea, it is more rational to use absorbable suture material.
