Abstract Background: The objective of the study was to study the influence of the combined use of hemodialysis (HD), chemisorption (HS), and metabolic plasmapheresis (PP) for the hemodynamic and defective reduction of intoxication in children with ARF. Methods: Investigations were performed in 63 children (at the age from 2 to 14 years old) with ARF that was developed as a result of prerenal (hypovolemia, septic shock) and renal (acute glomerulonephritis, pyelonephritis) factors. Depending on the devised detoxification methods, patients were divided into the control group (5) whom it was performed only HDmethod and the control group (58) with the use of methods of gravitational surgery, such as HS, HD, and PP. Results: General clinical presentation in all patients during admission was noted by the significance of intoxication syndrome, signs of respiratory, cardiovascular insufficiencies, in 84,2% of cases it was noted by mental confusion, in 72% of cases it was noted by anemic syndrome, in 78% of cases it was noted by hypoproteinemia and in 93% of cases it was noted by anuria. In 63 cases methods of complex treatment of children were performed once depending on the severity of the condition, a significant degree of the intoxication syndrome, and the level of changes in internal organs. Conclusion: The influence of sorption methods of detoxification in patients with AKI has a significant advantage over the sessions mono hemodialysis. The corrective effect of complex therapy affects the restoration of organ functions, reduction of intoxication syndrome, and improvement of the clinical condition of patients.
