Abstract

Abstract: Optimal intravenous fluid administration in critically ill patients is essential for effective hemodynamic management, particularly during episodes of shock. Over time, fluid resuscitation strategies have evolved from liberal approaches to restrictive and individualized methods in order to prevent both hypovolemia and fluid overload, especially considering that only about 50% of critically ill patients are truly fluid responsive.
Point-of-care ultrasound (POCUS) has emerged as a valuable, noninvasive bedside tool for assessing intravascular volume status and real-time hemodynamics. Several ultrasound-based techniques can be used, including cardiac ultrasound to evaluate preload, contractility, and afterload; lung ultrasound to detect pulmonary edema; and the Venous Excess Ultrasound Score (VExUS) to assess visceral venous congestion.
These ultrasound assessments provide essential information  on fluid responsiveness, right ventricular function, and tolerance to additional fluid administration. This enables clinicians to optimize fluid therapy while minimizing complications related to fluid overload. The integration of POCUS into clinical practice improves the ability of pediatric intensivists to tailor treatments to each patient’s hemodynamic profile, ultimately enhancing clinical outcomes. The combination of ultrasound and hemodynamic evaluation opens new possibilities for precision fluid management in the resuscitation of critically ill pediatric patients.

Resumen:  La administración óptima de fluidos intravenosos en pacientes críticos es fundamental para el manejo y monitoreo hemodinámico, especialmente durante episodios de shock. Este enfoque ha evolucionado de estrategias de reanimación líquida liberada a métodos restrictivos e individualizados, con el fin de evitar tanto hipovolemia como la sobrecarga
hídrica. La ecografía en el punto de atención (POCUS) en la actualidad es una herramienta no invasiva y con múltiples protocolos que nos ayudan en una mejor aproximación clínica. Se
destacan diversas técnicas ecográficas, incluyendo la evaluación de la función cardíaca (precarga, contractilidad y poscarga), así como la ecografía pulmonar y la valoración de la congestión vascular visceral mediante el protocolo VExUS. Estos métodos proporcionan información crítica sobre la tolerancia a fluidos, la respuesta a los mismos y el estado de la función ventricular, lo que es esencial para optimizar la terapia de fluidos y minimizar complicaciones asociadas a estados de hipovolemia, hipervolemia o mala distribución de volumen circulante. La interacción entre la ecografía y la evaluación hemodinámica tradicional es fundamental para una atención personalizada de la reanimación de pacientes pediátricos críticos
