RESUMEN
Resumen

Introducción:

En recién nacidos (RN) con encefalopatía hipóxico isquémica (EHI) en hipotermia se describen alte raciones metabólicas que se asocian a pronóstico neurológico. La hipomagnesemia ha sido reportada en la literatura, pero no es medida ni corregida en todos los centros de atención neonatal. Objeti vo Evaluar la frecuencia de hipomagnesemia e hipocalcemia en RN con EHI en tratamiento con hipotermia corporal total y evaluar la respuesta al aporte de sulfato de magnesio. Pacientes y Méto do Estudio prospectivo, observational y descriptivo en RN con EHI sometidos a hipotermia corporal total, hospitalizados entre los años 2016-2017. Se realizó medición seriada en sangre de magnesemia (Mg) y calcemia (Ca). Con Mg menor o igual de 1,8 mg/dl se administró suplemento como sulfato de Mg para mantener niveles entre 1,9 y 2,8 mg/dl. Se describió la frecuencia de hipomagnesemia e hipocalcemia y su presentación en el tiempo. Se realizó registro prospectivo de evolución clínica. Se hizo un análisis estadístico descriptivo, con medidas de tendencia central.

Resultados:

Se incluyeron 16 pacientes. Presentaron hipomagnesemia 13/16 (81,3%), la que fue precoz (6-36 h de vida), nor malizándose con aporte de sulfato de magnesio, requiriendo 2a dosis 4 de ellos. Presentaron hipo- calcemia 6/16 (37,5%).

Conclusiones:

La hipomagnesemia es frecuente (80%), similar a lo descrito en la literatura. Dado su importancia fisiológica debe controlarse y corregirse, de igual manera que el calcio.
ABSTRACT
Abstract

Introduction:

In newborns with the diagnosis of hypoxic-ischemic encephalopathy (HIE) treated with hypother mia, metabolic alterations are observed, which are associated with neurological prognosis. Hypo magnesemia has been reported frequently in the literature in these patients, but it is not measured or corrected in all neonatal healthcare centers.

Objective:

To evaluate the frequency of hypomag nesemia and hypocalcemia in newborns with HIE treated with whole-body hypothermia and to evaluate the response to the magnesium sulfate administration. Patients and

Method:

Prospective, observational and descriptive study in hospitalized newborns with the diagnosis of HIE and trea ted with whole-body hypothermia between the years 2016 and 2017. Serial blood measurement of magnesemia (Mg) and calcemia (Ca) was performed. When presenting an Mg level < 1.8 mg/dl, supplementation with magnesium sulfate was administered to maintain levels between 1.9 and 2.8 mg/dl. The frecuency of hypomagnesemia, hypocalcemia and clinical evolution was registered. A descriptive statistical analysis was performed, with central tendency measures.

Results:

Sixteen ca ses were included, 13 of them presented hypomagnesemia (81.3%), with early-onset (6-36 hours of life), which was normalized with magnesium sulfate treatment, receiving a second dose 4 patients. Six of 16 patients presented hypocalcemia (37.5 %).

Conclusions:

Hypomagnesemia is frequent (80%), similar to that described in the literature, and should be controlled and corrected early, given its physiological role, in the same way that calcium is controlled.
