[Clinical testing of the Bulgarian Diamex dialyzers]

The Bulgarian dialyzers "Diamex" were clinically tried as well as original patterns of the firm Fresenius--"Hemaflow" in 28 patients from the Centre of hemodialysis at the Medical academy. The results obtained for the clearances of Bulgarian dialyzers (urea clearance--2.61 ml/s, creatinine clearance--2.18 ml/s, clearance of inorganic phosphor--1.63 mg/s and clearance of uric acid--2.14 ml/s) and their ultrafiltration possibilities revealed no statistically significant difference as regards the data of the original patterns. No essential deviations in those indices with the first and third use of the dialyzers. The percentage of clearing during 4-hour hemodialysis, being 51.7% for urea, 48.2% for creatinine and 52.6% for uric acid, remains unaltered even with their third use. No allergic reactions have been established to the membrane in the groups of patients examined. It could be stress in conclusion that the Bulgarian dialyzers, according to quality and effectiveness, correspond to the original patterns could be used several times with no risk for the patients.
