DURAN-VEGA, Héctor César et al. Risk Factors for Development of Hypomagnesemia in the Burn Patient. Gac. Méd. Méx [online]. 2004, vol.140, n.6, pp.577-582. ISSN 2696-1288.

Electrolyte abnormalities are common in the severely burned patient. There is little information with regard to the frequency and magnitude of hypomagnesemia, as well as on risk factors for this condition. We performed an observational, retrospective analysis of 35 burned patients treated at the Plastic and Reconstructive Surgery Service at the Hospital Central Sur PEMEX, Mexico City. We determined serum magnesium behavior and divided patients into two groups: the first included 11 patients with burns and hypomagnesemia, and the second, 24 patients with burns but without hypomagnesemia. Risk factor identification was performed. We found patient at riskwas the one with more than 40% of 2nd or 3rd degree total burned body area, in day 4 or 10 after the burn, and with hypokalemia, hypocalcemia, or both, and without intravenous (i.v.) supplementation of magnesium. The best way to prevent or avoid major complications is to identify the high-risk patient, or to diagnose earlier.
