The Ratio of Femoral Vein Diameter to Femoral Artery Diameter to Predict Fluid Responsiveness in Children

Proper administration of intravenous fluids is an important part of treating circulatory failure in children and affects the clinical outcome of the management of the child's emergency. Giving a small amount of fluid will cause tissue hypoperfusion and worsen organ dysfunction and cause ischemia. On the other hand, excess fluid interferes with oxygen delivary, exacerbates treatment outcomes, increases complications, and extends both the length of the stay in intensive care and mortality. The use of bedside ultrasound by pediatric intensive care physicians has become so critical in recent years that it is now a component of physical examination in ICUs
