Electrolyte concentrations in serum and CSF following subarachnoid haemorrhage.
Serum and CSF calcium, magnesium, potassium and sodium were analyzed in 14 patients suffering from subarachnoid haemorrhage and in 10 healthy controls. The calcium and potassium concentrations in serum and CSF were decreased while magnesium unchanged and sodium were unchanged. A deranged electrolyte homeostasis was thus detectable in the CSF following subarachnoid haemorrhage. It could not be established whether symptoms of delayed cerebral ischemia were related to CSF calcium and/or potassium levels.
