ARIAS-MIRA, David Esteban  e  CAMACHO-OJEDA, Luis Alfonso. Ventilatory failure associated with extreme hypomagnesemia in a patient with ulcerative colitis: case report and literatura review. Iatreia [online]. 2021, vol.34, n.2, pp.151-155.  Epub 19-Maio-2021. ISSN 0121-0793.  https://doi.org/10.17533/udea.iatreia.73.

Hypomagnesemia is an electrolyte disorder associated with decreased nutritional intake, gastrointestinal losses, and renal clearance of magnesium, a divalent cation that, having a higher concentration at the intracellular level, makes it difficult to analyze its absolute deficit and establish an adequate correction that supplies daily losses and requirements; For this reason, knowledge of the etiologies of hypomagnesemia, as well as the calculation of the excreted fraction of magnesium and measurement of magnesiuria in 24 hours, are useful tools to establish adequate guidelines for continuous magnesium correction, in order to avoid complications associated with its toxicity or poor correction that perpetuates this electrolyte disorder, and generates the appearance of symptoms as severe as tetany and ventilatory failure. These severe manifestations were present in the patient described, who, in the absence of shock or base acid disorder, required admission to the intensive care unit for invasive mechanical ventilation and correction of their electrolyte disorders associated with ulcerative colitis (hypocalcemia, hypokalemia, and hypomagnesemia).
