This page and video provide tips for placing IVs in infants, emphasizing the use of a 24-gauge needle due to their small veins. It describes choosing the right site, like the foot or hand, and using transillumination to find veins. The scalp is an option if other sites fail but requires caution. Immobilizing infants with a blanket helps prevent movement during insertion. Poiseuille’s Law explains how fluid flow depends on factors like vein size and pressure difference. Warming techniques can help locate veins more easily by increasing blood flow without causing burns to delicate skin.
