Fluid and electrolyte imbalance related to intracranial abnormality

Background Maintenance of the tonicity of extracellular fluids is crucial for proper cell function. In children and adults, normal blood tonicity is maintained by a coordinated interaction among the thirst, vasopressin, and renal systems. Dysfunction in any of these systems can result in abnormal regulation of blood osmolality, which if not properly recognized and treated, may cause life-threatening dysfunction in neuronal and other cellular activities. The aim of this study is to increased awareness on the possibility of fluid and electrolyte imbalance in patients with intracranial abnormality.
