Abstract
Chronic hemodialysis patients are exposed to nearly 400- 500 liters of dialysate weekly, which is prepared by mixing up water for hemodialysis with concentrate for hemodialysis. The dialysate is separated from patient's blood only by a se-mipermeable membrane. Therefore it has to satisfy the strict standards of microbiological quality. Beside reporting our own results, this paper deals with microbiological quality of water for hemodialysis and dialysate, its determination, its influence on health and modes of its control, taking into consideration that after cardiovascular diseases, infections are the most common cause of death in this population. Analysing the results of regular microbiological tests carried out during a 6-month period, it has been found that, in spite of regular disinfections of the central water for hemodialysis treatment system and hemodialysis machines, 10% of the samples of water for hemodialysis and 21.43% of the samples of dialysate do not comply to the AAMI standards. No other bacterial strain except Pseudomonas species was identified.
During the observation period there were no pyrogenic reactions. The authors conclude that a significant percentage of the samples of water for hemodialysis and the samples of dialysate are not in accordance with the recommended standards. In spite of that, the obtained results do not differ significantly from the results of other authors.
