[Studies of disinfection of hemodialysis instruments].

Fever reactions in dialysis patients may partly be traced back to the transmission of pyrogens from the rinsing solution compartment into the sanguiferous system. The pyrogen concentration increases with the germ contents of the rinsing solution, which, therefore, should be kept as low as possible by suitable desinfection measures. For the artificial kidney Gambro AK 3 a hot water desinfection of 90 minutes at 90 degrees C or a formalin desinfection of 30 minutes, respectively, for the artificial kidney Leuven IIIC the formalin or peracetic acid desinfection of 30 minutes each proved to be sufficient.
