Ultrasound-guided Lumbar Erector Spinae Plane Block For Postoperative Analgesia in Femur Fracture: A Pediatric Case Report.

The erector spinae plane (ESP) block is a recently defined regional anesthesia technique which is considered as an effective method in postoperative multimodal analgesia. ESP block is usually performed at the thoracic region in pediatric patients, but it is also possible to perform ESP block at the lumbar region. Femur fracture is one of the most common procedures especially in pediatric orthopedic surgery where postoperative pain management is essential. We aim to present a case of effective postoperative analgesia provided by ultrasound-guided lumbar ESP block in a 6-year-old patient after femur fixation surgery.
