An interscalene block is a regional anesthesia technique used in procedural medicine, primarily for shoulder and upper arm surgeries. Performed under ultrasound guidance, this nerve block involves injecting local anesthetic near the brachial plexus in the interscalene groove, providing effective pain relief and muscle relaxation. Ultrasound guidance enhances safety by allowing real-time visualization of nerves, vessels, and needle placement, minimizing complications.
This ultrasound-guided interscalene block offers superior precision and faster onset compared to traditional landmark-based methods, making it a cornerstone in modern orthopedic and pain management procedures. It significantly reduces systemic opioid use and improves patient recovery. Key search terms: ultrasound-guided nerve block, regional anesthesia, shoulder surgery pain relief.
