Refractory Shock in Pediatric Emergency Departments: Challenges and Innovations in Early Escalation: A Narrative Review

Refractory shock in children carries persistently high mortality, particularly in low-resource settings. It occurs when circulatory failure persists despite adequate fluid resuscitation and vasoactive medications. This review summarizes pathophysiology, recognition, and escalation strategies for pediatric refractory shock, emphasizing early identification in the emergency department. It examines evidence for fluid management, vasoactive therapy, and point-of-care ultrasound in optimizing decision-making, along with second-line options such as corticosteroids, vasopressin, and milrinone. Special attention is given to resource-constrained settings, describing evidence-based adaptations including conservative fluid strategies from the FEAST trial, simplified algorithms, simulation-based training, and telemedicine. Improving outcomes requires rapid recognition, precise hemodynamic phenotyping, and timely evidence-based interventions.
