The Using of Projection Vein Finder in Veins for Peripheral Vascular Catheterization
Vascular access becomes more and more important for the caring of sick infants and children. Peripheral vascular catheterization provides a direct route for administration of fluids and medications. Many anatomic sites are available for intravenous (IV) catheterization, with peripheral sites being the most common and readily available.

Placing an IV line into a peripheral vein in a small child or infant can be difficult  for many reasons. Babies and infants have thinner peripheral veins, they may have more subcutaneous fat, prone to vasoconstriction. Baby or infant patients are less likely to remain motionless and cooperative during a painful procedure than adults. The scalp veins provide a secondary option for peripheral intravascular access in small children and infants because of minimal subcutaneous fat and less movement and the lack of a flexible joint; this reduces the likelihood of dislodging the catheter, which is common with IV catheters placed in the arms or legs.
