Back to the Future: Historic Insights and Recent Innovations in Pediatric Regional Anesthesia

Pediatric regional anesthesia is evolving with new peripheral nerve blocks and techniques aimed at improving perioperative pain management. While caudal blocks have long been standard due to their simplicity and low complication rates, newer fascial plane blocks offer comparable efficacy with enhanced nerve coverage tailored to specific surgeries. Moreover, adjuncts like dexmedetomidine and dexamethasone have shown promise in prolonging block duration and enhancing post-operative pain relief and patient satisfaction. The integration of these advancements into clinical practice has yielded significant benefits, including reduced intraoperative fluid requirements, decreased reliance on opioids postoperatively, earlier initiation of enteral nutrition, lower readmission rates, shorter hospital stays, and decreased overall hospital costs. Our review underscores the technical progress and expanding literature supporting the rapid adoption of these impactful regional anesthesia techniques in pediatric care.
