[Comparative study of hemodialysis methods].

An analysis of the results of chronic hemodialysis on central systems and individual apparatuses in 20 patients with the terminal stage of renal insufficiency was performed. It was established that the use of chemically pure water, disposable systems and dialyzers for hemodialysis ensured a decrease in the number of complications and improved the patients' rehabilitation. Bicarbonate hemodialysis proved to be a highly effective method for the treatment of patients with sodium acetate intolerance, decompensated metabolic acidosis and low arterial pressure. A single-needle approach to the patient's vascular system provided for a less marked decrease in uremic toxins, however statistically significant differences were undetectable as compared to the common methods.
