EXPERIMENTAL RESEACH OF EFFECTIVENESS OF ANTIMICROBIAL SURGICAL MATHERIALS CONTAINING DECAMETHOXINUM
National Pirogov Memorial Medical University, Vinnytsya, Ukraine
Objective. To study the properties of antimicrobial surgical materials containing decamethoxinum.
Methods. In the experimental model of the wound primary infected by Staphylococcus (60 white mongrel male rats), the antimicrobial effectiveness of dressings (medical coarse calico) and suture (silk) materials, impregnated with antiseptic decamethoxinum (with 1,10-Decamethylene-bis-(N,N-dimethylmethoxycarbonylmethyl) ammonium dichloride), in comparison with topical wound management with chlorhexidine was researched. The effectiveness of wound healing was studied experimentally by standard microbiological and morphological methods (3rd, 7th, 14th days).
Results. The decrease of S. aureus colonization in wounds (6.47±0.11 CFU/ml) was registered on the 3rd day after administration of antimicrobial silk and medical coarse calico with decamethoxinum. The use of materials, impregnated with decamethoxinum was proved to have advantages in reduction of S. aureus colonization (in 1.3-1.4 times) after 7 days. Complete reduction of S. aureus from wounds was registered on the 14th day. But at the same time, in the comparison group microbial colonization was higher than 106 CFU/ml (p<0.01).
In comparison group the pathomorphological changes of skin were noted such as a significant inflammation response, purulent inflammation extension in the derma (3rd day). While using antimicrobial silk and dressings with decamethoxinum, the depression of inflammatory reaction more than in 1.5 times was registered (p<0.05); exudation and purulent character of the inflammatory process was specified in the form of the expressed activation of leucocytes and macrophages in the first 7 days. In comparison group a long-lasting purulent inflammation was observed as well as progression of necrotic and dystrophic disorders (7th day). After using of surgical material, impregnated with decamethoxinum, the acceleration of reparation, more active wound healing were registered (7th, 14th day), than in comparison group (р<0.05).
Conclusions. The use of antimicrobial surgical materials, impregnated with decamethoxinum provides effective antimicrobial, anti-inflammatory and anti-edematous action; synchronizes cell interaction in healing of purulent wounds; creates the balance between maturation and resorption of granulations and scar tissue.
