Prevention of postoperative peritonitis and its complications

Abstract

Purpose: to develop a new method of lavage of the abdominal cavity in the experimental conditions.

Materials and methods. We treated 456 patients with postoperative peritonitis who were on treatment in the surgery department of the municipal non-profit enterprise Regional Clinical Hospital of Ivano-Frankivsk Regional Council in the period from 2000 to 2021. Patients are divided into 2 groups. The retrospective group consisted of 212 patients, prospective - 244 patients.

Research results and their discussion. The method of lavage of postoperative peritonitis was carried out as follows: during relaparotomy, after mechanical cleaning of the abdominal cavity from fecal masses, bile, blood clots, fibrin layers, the abdominal cavity washed twice with 2-3 l of 0.02% solution of decamethoxine at a temperature of 30-35 ° C. After removing the drug residues from the abdominal cavity, pour2 liters of solution for peritoneal dialysis Extranil at a temperature of370C, the active substance of which is icodextrin, not glucose, ie it is not a nutrient medium for microorganisms, but has antimicrobial action due to hyperosmolarity and exposure to hyperosmolarity and increases its adsorption properties. This is followed by drainage of the abdominal cavity from four points with polyvinyl chloride tubes, which are intimately fixed to the skin and blocked for 6 hours.
