Intraosseous access facts: which statement is true?

• A. Proximal tibia is a common IO site, and the sternum is not used
• B. Proximal tibia is not used; sternum is preferred
• C. IO access should be obtained only in the humerus
• D. IO access is contraindicated in the tibia

Answer: (A)

In pediatric emergencies, intraosseous access is a fast way to get fluids and medications when IV access is challenging. The proximal tibia is the standard, most commonly used IO site in children because it’s easy to locate just below the tibial tubercle and provides rapid entry into the marrow cavity with a high success rate. The sternum IO exists but isn’t routinely used in prehospital care or many pediatric protocols due to higher risk, required equipment, and training barriers. While other sites like the humerus can be used in some cases, this doesn’t contradict the fact that the tibia is the common site and the sternum is not routinely used.
