What are the intraosseous sites for pediatrics?

The selected answer is accurate because it outlines the primary intraosseous sites utilized for pediatric patients. When intravenous access is difficult or impossible, intraosseous access provides a rapid alternative for administering fluids and medications directly into the bone marrow, where they can quickly enter the circulatory system.

The proximal tibia is the most commonly used site due to its accessibility and safety profile. The proximal humerus is also appropriate and effective for this purpose, particularly in older children and adolescents. Finally, the distal femur can be accessed as a third site, though it is less commonly used than the other two.

These sites are favored in pediatric emergency practice because they facilitate quick access to the venous system in critical situations, which is essential for effective resuscitation and treatment.
