[The influence on water-electrolyte balance through osmotherapy for decreasing intracranial pressure].

On the basis of a group of neurosurgical patients showing a differing composition, various procedures of the dehydrating therapy in the pre- and postoperative phases for decreasing the increased intracranial pressure were studied. In addition to the continuous recording of the intracranial pressure, the electrolyte and water balance was measured by recording the plasma, urinary, and cerebrospinal-fluid electrolytes and their osmolarities and the urinary output was determined. Besides, specific measurements of the haematocrit, of the central venous pressure and the arterial mean pressure brought pathophysiological findings on the dehydration.
