The acute afections of center sistem nervous as the stroke(ACV) and head trauma produce alterations in the Sodio Homeostasis For various mechanisms.The Hiponatremia is a frecuently event in our enviroment, It is a Desafy because to diverse etiology, the complications of their natural evolution become severity and to fatalytis. Objective: To determine the frequency and causes of hyponatremia in adult patients with acute brain injury admitted to the National Hospital. Materials and methods: descriptive, cross-sectional prospective study that included 1 15 patients in the National Hospital (Itauguá, Paraguay) in 2015. It was considered as hyponatremia in acute brain carriers of hemorrhagic stroke (intracerebral, subarachnoid), ischemic stroke or head injury confirmed by computed tomography or magnetic resonance image in patients submitted less than 10 days and serum Na + ≤ 135 mEq/L. Results: The prevalence of hyponatremia was 34%, with a predominance of males (54%). The most common diagnosis was hemorrhagic stroke and the most common comorbidity was arterial hypertension. There were diagnosed 15 patients with Syndrome of inappropriate ADH secretion and 6 with Cerebral salt wasting syndrome representing 38.4% and 15.4% respectively. Conclusion: we found high prevalence of hyponatremia in patients with acute brain damage. The Syndrome of inappropriate ADH secretion and Cerebral salt wasting syndrome are described as the 2 syndromes that more frequently explain the presence of hyponatremia associated with increased natriuresis.
