Evaluation of hemodialysis efficiency by an edema fluid model.
The concentrations of urea, creatinine, and uric acid were measured in edema fluid and plasma during hemodialysis and 18 h after hemodialysis. The concentrations of these solutes in plasma were 15-17% lower than in the edema fluid after hemodialysis. Eighteen hours after hemodialysis, however, the concentrations in plasma were almost the same as those in edema fluid. These data suggest that the removal of these solutes from the extracellular space is delayed during hemodialysis. The plasma concentrations obtained at 18 h after hemodialysis are better indicators of hemodialysis efficiency.
