RESUMO
Purpose: This study compared outcomes of plating distal radius (DR) fractures using wide-awake local anesthesia no tourniquet (WALANT) versus general anesthesia (GA). Methods: From March 2018 to March 2019, 20 patients with DR fracture underwent plating using WALANT whereas 20 patients who underwent plating under GA were used as controls. Outcomes evaluated were pain control, waiting time for the operation, hemodynamic changes, blood loss, the occurrence of adverse effects of medications used in WALANT and GA, and the duration of postoperative stay. Results: The WALANT group experienced a significantly shorter waiting time for surgery (6 vs 20 days; P < .001) and a shorter postoperative stay (1 vs 2 days; P = .009) compared with the GA group. They also reported mild to no pain during surgery. The groups were similar with regard to blood pressure, blood loss, and operative time. None in the WALANT group required conversion to GA during surgery and no adverse effects were reported. Conclusions: The WALANT approach is a viable alternative to GA for plating of DR fractures. Type of study/level of evidence: Therapeutic III.
RESUMO
Fractures of the distal radius are one of the most common types of injuries encountered in hand surgery. Plate osteosynthesis is recommended for unstable fractures. Because distal radius fracture fixation is usually performed under general or regional anesthesia with the use of a tourniquet, this exposes patients, especially elderly people with extensive comorbidities, to adverse effects commonly associated with these forms of anesthesia. As such, many of these patients are unable to undergo surgery in a timely manner until they are deemed medically fit for surgery or anesthesia, and some may still be treated nonsurgically. Injecting local anesthetic of lidocaine and epinephrine into the surgical field and without using a tourniquet is known to be advantageous for various surgical procedures of the hand. However, this approach, also known as wide-awake local anesthesia no tourniquet (WALANT), has not been used in the fixation of fractures beyond the wrist. Using the WALANT approach as an alternative anesthetic for plating of distal radius fractures may enable patients who are normally denied surgery owing to their age or medical comorbidities to undergo plate fixation for the fractures. This article outlines the WALANT approach used for a single case of fixation of distal end radius fracture with a detailed description of the technique of administering local anesthesia.
