SUBSTANCE: first, Fraxiparine is inhaled for 5-10 minutes. A dialysis solution for peritoneal dialysis containing extranyl is administered into the abdominal cavity 1-1.5 hours later through a catheter. The solution additionally contains: albumin in the concentration of 35-40 g/l, heparin in the concentration of 500-750 Unit/l and papaverine in the concentration of 50-100 mg/l. Every 6-8 hours after the beginning of exposure of the dialysis solution in the abdominal cavity, the Fraxiparine inhalations are repeated. The time of a single exposure of the dialysis solution in the abdominal cavity makes 12-18 hours.

EFFECT: method provides effective body detoxification in the given category of patients by providing a high toxin clearance owing to a continuous high osmotic concentration of the solution and the dilatation of pre-capillary peritoneal arterioles, prevented inspissation of the albumin solution to the colloidal state and its inactivation that reduces a rate of the dialysis solution exchanges.
