Abstract Study objective In prehospital and emergency settings, vasoactive medications may need to be started through a peripheral intravenous catheter. Fear of extravasation and skin injury, with norepinephrine specifically, may prevent or delay peripheral vasopressor initiation, though studies from adults suggest the actual risk is low. We sought to study the risk of extravasation and skin injury with peripheral administration of norepinephrine in children in the prehospital setting. Methods We performed a retrospective study of pediatric patients (≤18 years) who received a vasopressor during prehospital transport. We collected data from retrieval and hospital records from 2 pediatric medical retrieval teams in the Paris/Ile‐de‐France region. Patients were eligible if they had documentation of distributive or obstructive shock and administration of norepinephrine through a peripheral catheter (intravenous or intraosseous) during retrieval. The primary outcomes were the occurrence of extravasation and evidence of skin injury. We also examined approach to norepinephrine administration (concentration, duration, proximal vs distal site) and hospital outcomes. Results Over a 3‐year‐period, 37 pediatric patients received norepinephrine through a peripheral catheter (33 intravenous, 4 intraosseous). Median patient age was 1.8 years. Thirty‐two patients (86.5%) had septic shock. The median total duration of norepinephrine infusion was almost 4 hours. One patient (2.7%, 95% confidence interval 0.5%, 13.8%) had suspected extravasation from a 24‐gauge intravenous catheter in the hand, with local skin hypoperfusion. Skin changes were noted after 135 minutes of norepinephrine infusion. Perfusion normalized after catheter removal, and there were no other sequelae. Conclusions In a 3‐year sample of pediatric patients from a large metropolitan area, we found only 1 patient with evidence of any harm with peripheral administration of norepinephrine. This finding is consistent with the adult literature but requires multicenter and multiyear investigation before a firm recommendation for this practice can be made.
