ABSTRACT

Resumen: Introducción: Este estudio tuvo por objetivo valorar las diferencias entre el tipo de fluidoterapia ini cial utilizada (sueros isotónicos o hipotónicos) en el desarrollo de hiponatremia, valores de cloro y to lerancia de las vías venosas. Pacientes y Método: Estudio retrospectivo de cohortes en una Unidad de Cuidados Intensivos Pediátricos (UCIP) de un hospital terciario. Se incluyeron niños menores de 15 años ingresados durante el primer semestre de los años 2010 y 2013, que recibieron fluidoterapia in travenosa, excluyéndose los sometidos a cirugía cardiaca, trasplantados renales y aquellos con ingreso inferior a 24 h. Se recogieron datos epidemiológicos, de comorbilidad y relacionados con el ingreso, tipo de suero recibido, valores de sodio y cloro en las primeras 72 h y la incidencia de extravasaciones de vías periféricas. Resultados: Se incluyeron 111 niños: 68 (61,3%) recibieron líquidos hipotónicos y 43 (38,7%) isotónicos. No hubo diferencias respecto a la patología y gravedad, ni tampoco en el volumen de líquidos recibido. Entre los pacientes que recibieron sueros hipotónicos, 28 (41,2%) pre sentaron hiponatremia, siendo esta moderada (Na <130 mEq/kg) en 11 de ellos, en comparación con 8 niños (18,6%) entre los que recibieron sueros isotónicos, registrando hiponatremia moderada solo en un caso (p=0,027). No se registró ningún caso de hipernatremia, ni hubo diferencias en los valores de cloro plasmático. Tampoco se objetivó mayor frecuencia de pérdida del acceso venoso utilizando la fluidoterapia isotónica (4,7% vs. 7,4%, p=0,704). Conclusión: El uso de líquidos iniciales isotóni cos en niños hospitalizados en UCIP se asocia con menor incidencia y gravedad de hiponatremia, sin cambio en la cloremia y es bien tolerado por las vías venosas periféricas.


Abstract: Introduction: The objective of this study was to evaluate the association between the type of initial fluid therapy used (isotonic or hypotonic solutions) and the development of hyponatremia, the plas ma chlorine values and the tolerance of venous access. Patients and Method: Retrospective cohort study in a Pediatric Intensive Care Unit (PICU) of a high complexity hospital. There were included children younger than 15 years old hospitalized during the first semester of 2010 and 2013 who recei ved intravenous maintenance fluid therapy, excluding patients undergoing cardiac surgery, kidney transplant and admissions that lasted less than 24 hours. Epidemiological, comorbidity and admis sion-related data were collected, including type of solution received, sodium and chlorine values in the first 72 hours of hospitalization and the incidence of extravasation of peripheral intravenous lines. Results: 111 children were included; 68 children (61.3%) were treated with hypotonic solutions and 43 (38.7%) with isotonic solutions. There were no differences in pathology and severity, and also in the volume of fluid received. Among the patients who received hypotonic solutions, 28 (41.2%) de veloped hyponatremia, wich was moderate (Na <130 mEq/Kg) in 11 cases, compared with 8 children (18.6%) who received isotonic solutions, with only one case of moderate hyponatremia (p = 0.027). No cases of hypernatremia were recorded, and there were no differences in plasma chlorine values. There was also no increased frequency of venous access loss in patients treated with isotonic solutions (4.7% versus 7.4%, p = 0.704). Conclusion: Treatment with initial isotonic solutions in children hos pitalized in PICU is associated with a lower incidence and severity of hyponatremia, without changes in the plasma chlorine values and it is well tolerated by peripheral intravenous lines.
