Utilidad de la fórmula de Adrogué-Madias en la estimación del sodio alcanzado post fluidoterapia en pacientes quemados.

Introduction: Adrogué -- Madias´ formula is widely used in hyponatremia to estimate the sodium achieved by fluid therapy, but no studies have been done to see its usefulness in burned patients. Objective: Determine the utility of the Adrogué -- Madias´ formula in the estimation of sodium achieved after fluid therapy in burned patients. Material and method: Descriptive cohort study. Population: patients aged <14 years with burns> 10% of BSA, and patients> 14 years with BSA> 15%, who arrive in the first 24 hours of the burn. The infusion volume was calculated according to SCQ. Arterial blood gas analysis was taken on admission and completed the first 24 hours to compare the sodium. Finally, the calculated sodium with the Adrogué -- Madias´ formula and the real sodium at 24 hours were compared. Results: population: 24 patients. 79.2% of the population had hyponatremia. Student's t-test for related samples compared the sodium obtained by Adrogué-Madias´ formula and the sodium at 24 hours, obtaining a value of t = 7.893 (95% IC, p = 0.000189). The Pearson correlation coefficient did not show statistical significance when relating the clinical characteristics with the difference between the sodium obtained by the Adrogué -- Madias´ formula and the sodium at 24 hours. Conclusion: the Adrogué -- Madias´ formula is not useful in the determination of sodium after fluid therapy in burned patients. [ABSTRACT FROM AUTHOR]
