Removal of Blood Ammonia by Hemodialysis.

Blood ammonia, as measured by the microdiffusion technic of Conway, is removed efficiently from the blood of dogs with elevated blood ammonia levels by a Kolff type artificial kidney with a dialyzing surface of 12,000 cm2. When flow through artificial kidney is 100 ml/minute the clearance of blood ammonia varies from about 50 ml/minute at lower arterial concentrations of blood ammonia to about 80 ml minute at higher arterial concentrations.
