Abstract

Fluid and electrolyte disturbances are common in critically ill neurosurgical patients, as central nervous system (CNS) damage may affect the brain’s ability to keep regulating their homeostasis. The potential consequences of fluid and electrolyte disturbances on the predamaged brain are profound and influence the development of cytotoxic or vasogenic brain edema, loss of cerebral autoregulation, increased intracranial pressure or decreased perfusion pressure. Early recognition and appropriate management of fluid and electrolyte disorders are important to minimize secondary brain damage.
