Abstract

Objective. To investigate the impact of the sorbtion-aspiration drainage system on background of hydroxyapatite and zinc oxide on experimental peritonitis.

Materials and methods. The experiment was performed on 55 white laboratory rat males, ageing 2 - 3 mo, with the body mass 225 - 250 g, which were kept in the typical vivarium conditions. Suspension of E. coli in physiological solution, 1.0 - 1.5 ml in concentration 1010 , was used for the peritoneum contamination. The suspension was introduced into abdominal cavity in the dose, dependent on the animal body mass, using the syringe for insulin injection. Peritonitis in the rats was developed in 48 h and characterized by intoxication, which exaggerated rapidly, as well as by intestinal motor disorders and pronounced microcirculatory disturbances. The experimental animals were distributed into 5 Groups. In patients of Group I the interventions were not performed (control); in laboratory animals of Group II peritonitis was not simulated, but the abdominal cavity was drained, using the sorption-aspiration drainage system; in laboratory animals of Group III peritonitis was simulated; in the Group IV of laboratory animals on background of peritonitis the abdominal cavity was drained, using the sorption-aspiration drainage system; in the Group V animals the abdominal cavity was drained by a standard silicon drain on background of peritonitis.

Results. Reduction of abdominal contamination by 43.12% and of histological features were produced in abdominal organs under the influence of the composite system, witnessing its bactericidal and sorption-antiinflammatory action.

Conclusion. Experimentally there was confirmed the possibility of application of sorption-aspiration drainage system on background of hydroxyapatite and zinc oxide in treatment of an acute peritonitis.
