Trastornos hidroelectrolíticos en postoperados de tumores cerebrales

In our series, the most frequent electrolyte disorder after surgery for CNS tumors was diabetes insipidus. Early treatment with desmopressin almost always prevents hypernatremia. Unless there is a surgical lesion of the hypothalamic-pituitary axis, spontaneous resolution will take place in 3 days on average. The management of SWS and SIADH requires close monitoring of plasma sodium due to the risk of hyponatremia.
