WALANT Versus Local Anesthesia With Tourniquet for Carpal Tunnel Decompression (WALANT vs LA-T)
2026년 5월 23일 업데이트: Mohamed Ahmed Tolba Abdelsalam, Misr University for Science and Technology
Intraoperative Pain During Carpal Tunnel Release: Wide-Awake Local Anesthesia No Tourniquet Versus Local Anesthesia and Tourniquet - A Randomized Controlled Trial
This multicenter, randomized, double-blinded controlled trial compared two local anesthetic techniques for open carpal tunnel decompression in adults.
The wide-awake local anesthesia no tourniquet (WALANT) technique uses lidocaine with epinephrine and no tourniquet, whereas the conventional technique uses lidocaine only with a pneumatic tourniquet (LA-T).
One hundred adults with carpal tunnel syndrome were randomized 1:1 to WALANT or LA-T at two tertiary university hospitals in Egypt.
The primary objective was to compare intraoperative pain during surgery.
Secondary objectives included pain during infiltration, tourniquet pain (LA-T only), operative time, patient satisfaction, and intraoperative complications.

상세 설명
Carpal tunnel decompression (CTD) is one of the most frequently performed hand procedures, and the optimal anesthetic technique remains debated.
Traditionally, CTD has been performed under local anesthesia with a pneumatic tourniquet (LA-T), regional block, or general anesthesia; these approaches may cause tourniquet pain, require sedation, and increase resource use.
Wide-awake local anesthesia no tourniquet (WALANT), using lidocaine with epinephrine infiltrated directly into the operative field, avoids the tourniquet and sedation while allowing intraoperative assessment of hand function.
We conducted a multicenter, prospective, double-blinded randomized controlled trial comparing WALANT to LA-T for open CTD at two academic tertiary centers (an orthopedic surgery department in Giza and a neurosurgery department in Cairo) between December 2024 and December 2025.
Adults with clinically and electrophysiologically confirmed carpal tunnel syndrome (CTS), ASA I-II, and eligible for surgical treatment were randomized 1:1 to WALANT (lidocaine with epinephrine, no tourniquet) or LA-T (lidocaine only with tourniquet).
The primary outcome was overall intraoperative pain scored on a visual analog scale (VAS, 0-10).
Secondary outcomes were pain during anesthetic infiltration, tourniquet pain (LA-T only), operative time, global patient satisfaction with the operating room experience, and intraoperative complications.
Blinded assessors collected outcome data using standardized questionnaires immediately after surgery.
A total of 100 patients were randomized (50 per group).
The study adhered to the Declaration of Helsinki and CONSORT 2025 guidelines and received prior institutional ethics committee approval.

실험적: WALANT (Wide-Awake Local Anesthesia No Tourniquet)
"Patients received wide-awake local anesthesia with epinephrine infiltration in the operative field, without arm tourniquet or routine sedation, for open carpal tunnel decompression."
|
"Twenty milliliters of 1% lidocaine (200 mg) with epinephrine 1:100,000, buffered with 8.4% sodium bicarbonate at a 10:1 ratio, were infiltrated into the operative field approximately 20 minutes before incision.
No tourniquet was applied.
A mini-open CTD through a 2-3 cm incision was performed in a minor procedure room under full aseptic technique.
Hemostasis relied on epinephrine-mediated vasoconstriction and meticulous surgery."

활성 비교기: Local Anesthesia With Tourniquet (LA-T)
"Patients received buffered lidocaine without epinephrine and an upper-arm pneumatic tourniquet for open carpal tunnel decompression."
|
"Twenty milliliters of 1% lidocaine (200 mg) buffered identically to the WALANT solution but without epinephrine were infiltrated approximately 5 minutes before incision in the operating room.
A blood pressure cuff tourniquet was placed above the elbow, inflated to 100 mmHg above systolic pressure after arm elevation and draping, and released after wound closure.
Mini-open CTD was performed through a 2-3 cm incision under standard aseptic conditions."
