RESUMO

Introducción. Las soluciones hipotónicas se han vinculado a la producción de hiponatremia iatrogénica. Objetivos. Evaluar las variaciones en el sodio sérico (NaS) tras la administración de una solución de mantenimiento intravenosa isotónica (NaCl al 0,9% en dextrosa al 5%) en comparación con una solución de mantenimiento hipotónica (NaCl al 0,45% en dextrosa al 5%). Material y métodos. Ensayo clínico aleatorizado, doble ciego y controlado. Se enrolaron pacientes pediátricos con una estadía esperada en la unidad de cuidados intensivos mayor de 24 horas, NaS normal y líquidos intravenosos > 80% de los líquidos totales de mantenimiento. La concentración sérica de Na se midió antes de colocar la solución de mantenimiento y al reducir la administración de ésta a < 80% del total del aporte. Resultados. Se incorporaron 63 pacientes, que fueron asignados en forma aleatoria a recibir una solución de mantenimiento hipotónica (n= 32) o isotónica (n= 31). Las características basales fueron similares en ambos grupos. No hubo diferencias con respecto a la cantidad de solución administrada (grupo hipotónico 865 ± 853 ml; grupo isotónico 778 ± 649 ml, p= 0,654) o el tiempo de infusión (grupo hipotónico: 24 ± 10,8 horas; grupo isotónico: 27,6 ± 12,8 horas, p= 0,231). Se encontró una diferencia en el NaS luego de la administración de las soluciones de mantenimiento (grupo hipotónico: 137,8 ± 4,3 mmol/L; grupo isotónico: 140,0 ± 4,1 mmol/L, p=0,04). Ninguna de las dos soluciones de mantenimiento aumentó el riesgo de hiponatremia (Na < 135 mmol/L) o de hipernatremia (Na > 145 mmol/L). Conclusiones. Ambas soluciones de mantenimiento, en 24 horas de infusión, no aumentaron el riesgo de producir hiponatremia iatrogénica.


Introduction: Hypotonic fluids have been associated with the development of iatrogenic hyponatremia. Objectives. To assess variations in serum sodium (sNa) following the intravenous administration of isotonic maintenance fluids (0.9% NaCl/5% dextrose) compared to hypotonic maintenance fluids (0.45% NaCl/5% dextrose). Material and Methods. Randomized, controlled, double-blind clinical trial. Pediatric patients with an expected length of stay in the intensive care unit of more than 24 hours were enrolled, with normal serum Na, and IV fluids >80% of total maintenance fluids. Serum Na level was measured before administering maintenance fluids and when reducing the administration to <80% of total fluids. Results. The study included 63 patients who were randomly assigned to receive hypotonic (n= 32) or isotonic (n= 31) maintenance fluids. Baseline characteristics were similar inboth groups. There were no differences in terms of volume of fluid administered (hypotonic group: 865 ± 853 mL; isotonic group: 778 ± 649 mL; p=0.654) or infusion duration (hypotonic group: 24 ± 10.8 hours; isotonic group: 27.6 ± 12.8 hours; p= 0.231). A difference was found in the serum Na following the administration of maintenance fluids (hypotonic group: 137.8 ± 4.3 mmol/L; isotonic group: 140.0 ±4.1 mmol/L, p= 0.04). None of these two maintenance fluids increased the risk of hyponatremia (Na <135 mmol/L) or hypernatremia (Na >145 mmol/L). Conclusions. Neither hypotonic nor isotonic maintenance fluids increased the risk of developing iatrogenic hyponatremia with the 24 hour infusion.
