ObjectivesFemur fractures are painful, and use of systemic opioids and other sedatives can be dangerous in pediatric patients. The fascia iliaca compartment nerve block and femoral nerve block are regional anesthesia techniques to provide analgesia by anesthetizing the femoral nerve. They are widely used in adult patients and are associated with good effect and reduced opioid use. Ultrasound (US) guidance of nerve blocks can increase their safety and efficacy. We sought to report on the use and safety of US-guided regional anesthesia of the femoral nerve performed by emergency physicians for femur fractures in 6 pediatric emergency departments.MethodsRecords were queried at 6 pediatric EDs across North America to identify patients with femur fractures managed with US-guided regional anesthesia of the femoral nerve between January 1, 2016, and May 1, 2021. Data were abstracted regarding demographics, injury pattern, nerve block technique, and analgesic use before and after nerve block.ResultsEighty-five cases were identified. Median age was 5 years (interquartile range, 2-9 years). Most patients were male and had sustained blunt trauma (59% low-mechanism falls). Ninety-four percent of injuries were managed operatively. Most patients (79%) received intravenous opioid analgesia before their nerve block. Ropivacaine was the most common local anesthetic used (69% of blocks). No procedural complications or adverse effects were identified.ConclusionsUltrasound-guided regional anesthesia of the femoral nerve is widely performed and can be performed safely on pediatric patients by emergency physicians and trainees in the pediatric emergency department.Copyright © 2022 Wolters Kluwer Health, Inc.
