Using scalp veins for peripheral vascular catheterization
Update:2017-03-24
Vascular access becomes more and more important for the care 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 most readily available.

Placing an IV line into a peripheral vein in a small child or infant can be a difficult task, for many reasons. Small children and infants have smaller peripheral veins, they may have more subcutaneous fat, they are prone to vasoconstriction, and they are much 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.
