Summary

This study tested if a simpler numbing method called WALANT works as well as a standard arm block for carpal tunnel release surgery. WALANT involves injecting numbing medicine directly into the wrist area, avoiding the need for a tourniquet or sedation. The trial included 130 adults having endoscopic carpal tunnel release, and measured whether extra pain relief was needed during surgery. The goal is to offer a safe, effective option that may shorten hospital stays and simplify the procedure.
