Why is intraosseous access often preferred during pediatric resuscitation?

• A. It is more comfortable for patient
• B. It provides rapid vascular access when IV access is difficult or delayed
• C. It must be used for all pediatric resuscitations
• D. It is used only after IV access is established

Answer: (B)

During pediatric resuscitation the priority is to deliver drugs and fluids as quickly as possible. Intraosseous access is preferred because it provides a rapid, reliable route to the central circulation when IV access is difficult or delayed, which is common in young kids with small, collapsed, or poor-tugor veins. Medications and fluids given into the bone marrow enter the venous system quickly, with onset similar to IV administration, and this can be established rapidly even while CPR is ongoing. This makes IO especially useful when you anticipate that finding IV access will take time; you can switch to IV later if it becomes available, but IO avoids wasting valuable minutes. It isn’t chosen for comfort, isn’t required for every pediatric resuscitation, and isn’t used only after IV access is established—the key idea is speed and reliability when IV access is hard to obtain.
