Neonatal sampling essentials
Heel site selection
Heel puncture site selection
- The medial or lateral plantar surface is the recommended location1
- Avoid the posterior curvature of the heel and central area of the foot (the arch†) because the bone/growth plates are very near the surface and there is a risk of damage/infection
- Avoid swollen areas and previous puncture sites2
Never use a toe for puncture. The heel is the preferred site for babies under six months old3*/ babies who are not yet walking
