Naloxone can be administered to pediatric patients in overdose resuscitation via which routes?

• A. IV/IO
• B. Oral
• C. Intranasal
• D. Subcutaneous

Answer: (A)

In pediatric overdose resuscitation, the priority is rapid and reliable reversal of opioid-induced respiratory depression, with a dose that can be titrated to restore ventilation promptly. Delivering naloxone through an IV or IO route achieves this because it provides immediate systemic absorption and a predictable onset, allowing clinicians to quickly assess response and adjust dosing as needed. IO access is especially valuable in children when IV access is difficult or delays the resuscitation process, ensuring you can deliver naloxone without interrupting airway support.

Other routes have drawbacks in this acute setting. Oral naloxone is poorly reliable in emergencies due to unpredictable absorption and first-pass metabolism, making it unsuitable for rapid reversal. Intranasal naloxone, while useful in prehospital or less urgent situations and when IV/IO access isn’t available, has more variable absorption and a slower, less controllable onset, which can be problematic during resuscitation. Subcutaneous administration is also slower and less predictable in onset and duration, making it less ideal for urgent reversal and titration.

So, the fastest, most controllable option in pediatric overdose resuscitation is intravenous or intraosseous administration.
