[High-efficiency membranes and the dialysis solution].

During this work through the total bacterial count and of the pseudomonas and the determination of the positive substances to Limulus Amebocyte Lysate test, bacterial pollution of the liquid bicarbonate concentrate has been determined together with the influence that preparation conditions and the entity of interval between the said preparation and utilization of concentrates have on it. Through the evaluation of the cardiac rate and the systemic arterial pressure, we have studied the influence of the bacterial pollution on the clinical of the patient. Analysing the obtained data we can point out that the liquid bicarbonate concentrate present an elevated degree of contamination which feels the effects of the production and storage procedures. The remark of inverse correlation between systemic arterial pressure and endotoxin level of the dialysate seems to reconfirm the importance of the bacterial contamination on the clinical of the patient.
