[The effect of heparin on the lipid level during hemodialysis]

The level of free fatty acids, triglycerides, and total lipids was studied in dynamics during hemodialysis. At the beginning of hemodialysis, fatty acids are discharged into the blood flow and their level at 20 min of hemodialysis is three-fold the initial level. Plasma triglycerides, which are components of lipoproteins, are the source of the discharge of free fatty acids. This is confirmed by the fact that the triglyceride content reduces simultaneously with the increase in the level of free fatty acids. The concentration of total lipids practically does not change during hemodialysis. The possible significance of a sharp increase of the free fatty acid level during hemodialysis is discussed.
