What is the correct IO lidocaine dose for pediatric infusion pain management?

• A. 1 mg/kg IO (Max dose 40 mg)
• B. 0.5 mg/kg IO (Max dose 20 mg)
• C. 1 mg/kg IV (Max dose 40 mg)
• D. 2 mg/kg IO (Max dose 80 mg)

Answer: (A)

The key idea is using lidocaine directly through the intraosseous route to numb the bone and periosteum before IO fluid administration, so the infusion pain is minimized for pediatric patients. 1 mg/kg given IO, with a maximum of 40 mg, provides enough local anesthesia at the IO site to blunt pain from rapid infusions while staying within a safe total lidocaine exposure for children. The 40 mg cap protects smaller patients from potential toxicity, ensuring you don’t exceed a safe systemic dose even if the child weighs less. A lower dose, or using a different route like IV, either may not provide sufficient local numbness at the IO site or isn’t the intended mechanism for this specific pain control. A higher dose (such as 2 mg/kg) increases the risk of lidocaine toxicity without additional benefit for this indication.
