Using a heel stick lancet requires careful technique, especially when performed on infants. The goal is to obtain a blood sample with minimal discomfort and risk to the baby. According to best practices, here’s how to use a heel stick lancet effectively:
Preparation
- Positioning: Ensure the baby's leg is lower than their heart to promote blood flow to the heel.
Lancet Selection
- Lancet Size: Use a lancet that is 1.0mm deep by 2.5mm long for healthy infants.
- Premature Infants: Use a smaller lancet for premature or low birth weight babies.
Puncture Site
- Safe Zone: Puncture the heel within the shaded area only, avoiding the central area of the heel to prevent bone injury.
