OBJECTIVE: Hydroelectrolytic disturbances are part of the complications of subarachnoid hemorrhage. Cerebral salt wasting syndrome (CSWS) must be considered when hyponatremia is associated with a decrease in circulating volume. We performed this study to determine the clinical characteristics and management paradigm of patients with serum sodium concentration abnormalities and aneurysmatic subarachnoid hemorrhage.
METHODS: We analyzed retrospectively clinical and laboratory data from eight patients with subarachnoid hemorrhage due to rupture of an intracranial saccular aneurysm and cerebral salt wasting syndrome. Their course, as well as their clinical findings and treatment, are described.
RESULTS: In eight patients, hyponatremia that lasted for more than 24 hours was detected (serum sodium under 135 mEq/l). The sodium disturbance occurred between day 3 and day 10 in all cases, in six of them in day 7 or day 8. The specific treatment for CSWS was to increase volume delivery according to the characteristics of the patient. Except for one case, none of the remaining patients required more than 72 hours of treatment to correct hyponatremia. No treatment-related complications were found
CONCLUSION: Cerebral salt wasting syndrome, occurring in some patients with subarachnoid hemorrhage, is more commonly related to certain specific anatomic locations of the ruptured aneurysm, responds to sodium replacement therapy and fluids and can be diagnosed and treated based on the clinical, hydroelectrolytic and hemodynamic course of the patient. Further studies are needed to define the underlying mechanism of this condition.
