Abstract

Background The Wide-Awake-Local-Anaesthesia-No-Tourniquet (WALANT) technique achieves an almost bloodless field for clear visualization during surgeries. WALANT utilizes lidocaine and epinephrine for anesthesia and hemostasis, respectively, without the usage of sedation and tourniquet. This avoids the potential side effects of tourniquet-related pain and sedation-related complications. However, acceptance is still low due to concerns regarding the safety of epinephrine injection in the finger. There is a persistent belief that epinephrine can cause digital ischemia. Purpose To evaluate retrospectively possible complications of hand surgeries performed using the WALANT technique. Methods All finger and hand procedures performed under the WALANT technique from June 2016 to May 2021 in an urban tertiary hospital were studied retrospectively. Results There were a total of 1073 cases, of which 694 were females and 379 were males. The mean age was 55 years. Finger surgeries (e.g., trigger finger release, excision of finger lesions, removal of implants) consisted of 707 cases; and the rest (366 cases) were hand surgeries (e.g., carpal tunnel release, excision of hand lesions, removal of implants). In all cases reviewed, there were no instances of circulatory compromise. There were also no circumstances where usage of reversal with phentolamine is recorded. Conclusion We believe that performing finger and hand surgeries using the WALANT technique is safe and beneficial. The usage of WALANT in hand surgeries avoids tourniquet pain. However, WALANT should be used with caution in those with vascular insufficiency or disease.
