Forearm ultrasound-guided nerve blocks vs landmark-based wrist blocks for hand anesthesia in healthy volunteers

摘要

Objective: Although ultrasound-guided regional nerve blocks have become more commonplace in the emergency department, there is no evidence to suggest that they are more effective than traditional landmark-based wrist blocks for hand anesthesia. We hypothesized that ultrasound-guided forearm nerve blocks would provide superior analgesia as compared with conventional landmark-based wrist blocks.
