Pediatric Ewing’s sarcoma and chronic pain prevention: a case of effective regional anesthesia in knee disarticulation
Luis Alberto Rodriguez Linares, Thaylana Saraiva Barroso
Abstract
We present the case of a 5-year-old child with Ewing’s sarcoma of the femur undergoing knee disarticulation. Multimodal analgesia was complemented with ultrasound-guided regional anesthesia using femoral and sciatic nerve blocks. This strategy provided excellent perioperative analgesia, minimized opioid consumption, and contributed to the prevention of chronic pain. The case highlights the role of regional anesthesia not only in optimizing immediate postoperative comfort but also in reducing the risk of long-term pain syndromes in pediatric oncologic surgery.
