Sodium Disorder

Patients with subarachnoid hemorrhage are prone to suffer from dysnatriemia. Evidence shows that hyponatriemia is associated with increased incidence of vasospasm, brain swelling and mortality in these patients. Patients with subarachnoid hemorrhage often require large amounts of iv fluids in order to maintain euvolemia and support cardiocirculatory function. Prior evidence shows that the type of infusion fluid significantly influences blood sodium content. Hence, this study evaluated whether the sodium content of the infusion solution impacts mortality and morbidity in patients with subarachnoid hemorrhage.
