Algoritmo Salt-us en la Hiponatremia del Paciente Neurocrítico

Abstract: Hyponatremia is the most common electrolyte imbalance, defined as a plasma sodium concentration below 135 mmol/L. In neurocritical patients, this condition is the most common dystonia, with a significant contribution to hospital morbidity and mortality. In addition, among acute brain diseases, severe head trauma and aneurysmal subarachnoid hemorrhage are those with the highest incidence of hyponatremia. In hospitalized patients, hyponatremia has an incidence of approximately 30%, and in ICU settings, it ranges from 12% to 34%. Hyponatremia in the Intensive Care Unit has been shown to increase hospital mortality from 16% to 28%. Cerebral salt wasting syndrome and syndrome of inappropriate antidiuretic hormone secretion have been classified as the most common etiologies of hyponatremia in neurocritical patients.
