In pediatric arrest, when should intraosseous access be used?

• A. Only after IV access is obtained.
• B. Never.
• C. If IV access is easily obtained.
• D. When IV access cannot be obtained quickly or is unsuccessful after attempts.

Answer: (D)

During pediatric arrest, getting medications and fluids into the circulation fast is essential because delays can worsen outcomes. IV access can be very hard to obtain in young children, often taking time or failing after multiple attempts. Intraosseous access offers a rapid, reliable route by placing a needle into the bone marrow, which quickly delivers meds and fluids into the central circulation. The best use is when IV access cannot be obtained quickly or after unsuccessful IV attempts. If IV access is obtained rapidly and easily, IO isn’t needed. In urgent situations, starting IO promptly helps avoid delays in delivering life-saving medications while IV access is pursued in parallel.
