RAD-57 reading of 15% in pediatric patients requires consideration for hyperbaric center referral.

RAD-57 reading of 15% in pediatric patients requires consideration for hyperbaric center referral.

• A. Yes
• B. No
• C. Only if symptomatic
• D. Not at all

Answer: (A)

A RAD-57 reading estimates methemoglobin levels, and a pediatric MetHb around 15% is a meaningful elevation that can cause tissue hypoxia even if the child isn’t severely symptomatic yet. In children, moderate methemoglobinemia carries enough risk that escalation of care is appropriate, especially because methylene blue—the usual antidote—has contraindications in some patients (like G6PD deficiency) or may not yield rapid enough improvement in all cases. When methemoglobinemia is present at this level, hyperbaric oxygen therapy becomes a consideration because it increases dissolved oxygen in the blood and can help improve oxygen delivery while the methemoglobin burden is addressed or until definitive therapy works. For that reason, referrals to a hyperbaric center should be considered for a pediatric patient with a 15% RAD-57 reading.
