What finding indicates infiltration at an IV infusion site in an infant?

Edema in the palm of the hand is a significant indicator of infiltration at an IV infusion site, especially in infants. Infiltration occurs when the IV fluid leaks into the surrounding tissue instead of being delivered directly into the vein. When this leakage happens, the affected area may become swollen due to the accumulation of fluid, resulting in edema. In infants, this can often be observed in the palms or around the IV site.

Infiltration may not always present with redness, pain, or coolness right away. While redness and pain may indicate phlebitis or irritation, coolness may indicate reduced blood flow or a more severe issue such as an occluded vein. Thus, observing edema specifically points to leakage of fluid in the tissues, making it a key sign of infiltration and confirming that the IV isn't functioning properly. This knowledge is crucial for prompt intervention to prevent further complications in pediatric patients.
