Which IO size is used for pediatric patients?

• A. Pink 15 mm
• B. Blue 25 mm
• C. Yellow 45 mm
• D. Green - Sternal IO

Answer: (A)

Intraosseous needle length must match the patient’s size. Pediatric bones are smaller and the marrow cavity is shallower, so using a shorter needle helps you reach the medullary space without penetrating through the far cortex or into surrounding tissues. The pink 15 mm size is designed for this purpose in children, providing safe, effective access for most pediatric patients. Longer needles (blue 25 mm, yellow 45 mm) are intended for larger patients or adults, where more depth is needed. The green sternal IO is a different access site option and not the standard pediatric limb approach. So the pink 15 mm length is the appropriate choice for pediatric IO access.
