Summary

This pilot study will evaluate the latency of onset and duration of sensory-motor block in patients undergoing hand surgery. Patients will be randomized to receive nerve blocks of the distal forearm or of the distal and proximal forearm. Local anesthetic will be injected to anesthetise the median and ulnar nerves in the distal forearm (1-injection site group) or the median and ulnar nerves in the distal and proximal forearm (2-sequential injection sites group) to accomplish anesthesia for surgery on the hand.

Conditions

• Carpal Tunnel Syndrome
