SANCHEZ-DIAZ, Jesús Salvador et al. Dysnatremia: a precise, solid and concise approach. Med. crít. (Col. Mex. Med. Crít.) [online]. 2021, vol.35, n.6, pp.342-353.  Epub Sep 19, 2022. ISSN 2448-8909.  https://doi.org/10.35366/103721.

Dysnatremia is the most frequent electrolyte alteration in critically ill patients, with repercussions on morbidity and mortality. Sodium is the most important regulating electrolyte of blood osmolarity; the inherent relationship with the water molecule makes this pair have an interdependent and reciprocal ratio. Through this unsystematic review of the literature, the aim is to expose the physiology of sodium and the interaction with water, the pathophysiological mechanisms that lead to extremes in serum concentration, as well as diagnostic and therapeutic algorithms; so that medical decisions can be made in a precise, solid and concise manner.

Keywords : Dysnatremia; sodium; water; osmolarity; electrolyte.
