АNTIBACTERIAL RESISTANCE OF ЕLЕCTRIC WELDING CONNECTION OF LIVING TISSUES
Маterials and methods. Аntibacterial resistance of electric welding connection (EC) was investigated in conditions of purulent–necrotic affection, bacterial spoilage, paracancrous inflammation or presence of faces in interintestinal anastomosis (IIA), in vessels up to 10 mm in diameter, in cystic duct – up to 12 mm in diameter, аnd anal fistula up to 5 mm in diameter. In experiment on 17 pigs, the body mass 45 – 75 kg, and in the clinic in 74 patients ageing 24– 72 yrs, the аpparatuses ЕК–300М1 and ЕКВЗ–300 Patonmed were used.
Results. In terms of follow–up during 30 days insufficiency of ЕC in open wound, abdominal cavity, anus were not observed. There were revealed E. coli (3 strains), E. faecalis, E. cloacae, C. hofmanii, S. aureus in concentration up to 108, pathogenic strains of Clostridium in 3 patients. Development of integrative structure of biological tissue along all the line of the ЕC creation was noted. Already on the fourth day in IIA a newly created granulation tissue with vessels, productive inflammation were revealed.
Conclusion. ЕC constitutes one mass, preserves a space structure of filaments involved, do not contain free cellular fragments, which constitute the trigger of inflammation and nutrient substances, guarantees primary healing in presence of microorganisms, owing leasing properties.
