Safety and Pain Reduction in Emergency Practitioner Ultrasound-Guided Nerve Blocks: A One-Year Retrospective Study.

Study Objective: Emergency practitioners use ultrasound-guided nerve blocks to alleviate pain. This study represents the largest registry of single-injection ultrasound-guided nerve blocks performed in an emergency department (ED) to date. We wished to assess the safety and pain score reductions associated with ED-performed ultrasound-guided nerve blocks.
