Summary
Carpal tunnel syndrome (CTS) is a common medical condition that remains one of the most frequently reported forms of median nerve compression. Surgical procedure is a treatment option for CTS. For this surgery of the upper extremity, regional anesthesia (RA) is the strategy that should be systematically preferred because it is associated with shorter postanesthetic care and less pain compared to general anesthesia. Multiple approaches to block the brachial plexus are available for the surgery of the upper extremity below the elbow, but the axillary block (BAX) remains the most common approach as it is associated with low side effects. One of the most significant recent advances in the surgery of the upper extremity has been the emergence of Wide-Awake Local Anesthesia No Tourniquet (WALANT) technique. WALANT is an infiltration technique of a local anesthetic (LA) (lidocaine) and a hemostatic agent (epinephrine) directly into the operative site to induce anesthesia and hemostasis in the area of the surgical procedure to provide conditions suitable for hand surgery without sedation and tourniquet. Given its effectiveness and low side effects, WALANT could be a technique of choice in ambulatory surgery. The main objective of this non-inferiority, prospective, randomized, open-label, parallel-group controlled trial is to assess the efficacy of WALANT technique compared to BAX in carpal tunnel release (CTR).
