Potassium transfer from brain to blood during sustained hyponatraemia in the newborn calf.
The effect of dilutional hyponatraemia on cerebral blood flow and oxygen consumption, and net transfer of K+ to the circulation from brain tissue drained by the sagittal sinus was investigated in anaesthetized calves. Cerebral blood flow decreased, and net transfer of K+ to the circulation increased during hyponatraemia.
