RESUMO
Blood urea nitrogen (BUN) is thought to be a useful marker of the concentration of other solutes that underly the manifestation of uremia. By monitoring quality assurance parameters, 8 out of 57 dialysis patients were found during monthly blood work exams to have BUN greater than 100 mg/dl. An "Inadequate Dialysis Checklist" was designed for hemodialysis and peritoneal dialysis and used to assess all eight patients' treatments. The dialysis was corrected or integrally modified. As a result, the number of patients with BUN greater than 100 mg/dl decreased. These checklists can be useful for case managers to assess and evaluate dialysis variables.

With the use of the canine experimental model, the accuracy and reliability of coagulation test results were compared between arterial samples and samples obtained by venipuncture. The age of the catheter, the concentration of the heparinized flush solution, and the minimum discard volume were evaluated to obtain coagulation study results free of heparin effect. Thirty-seven paired samples of PT, aPTT, and TT were obtained. Analyses revealed no significant difference in test results between new lines and 7-day-old lines, nor between heparin concentrations of 1 unit/ml, 2 units/ml, or 4 units/ml. A minimum discard volume of five times the dead space (measured from catheter tip to sampling proximal stopcock) resulted in accurate and reliable PT, aPTT, and TT test results from the arterial catheters.
