Clinical analysis and management of hyponatremia in neurosurgical patients

Abstract

Objective To discuss the clinical characteristics,differential diagnosis and management principles of various types of hyponatremia in neurosurgical patients.Methods The clinical data of 76 cases of hyponatremia in neurosurgical patients were analyzed retrospectively.According to etiological factors,all patients were treated corresponding to their differential diagnosis.Results In 76patients,hyponatremia occurred due to inadequate supplement and diuretic in 40 cases,diabetes insipidus in 15,cerebral salt wasting syndrome in 12 and syndrome of inappropriate secretion of antiduretic hormone in 9.All patients had been treated to return to new balance.Conclusions The common causes of hyponatremia in neurosurgical patients are inadequate sodium supplement and diuretic,diabetes insipidus,cerebral salt wasting syndrome and syndrome of inappropriate secretion of antidiuretic hormone.As long as hyponatremia is detected early and treated timely to the above causes,all patients could have good prognosis.
