WALANT technique versus locoregional anesthesia in the surgical management of metacarpal and phalangeal fractures: Lessons from the Covid-19 crisis.

ABSTRACT

Wide Awake Local Anesthesia No Tourniquet (WALANT) is an anesthetic method which uses a local injection of anesthetic and epinephrine, avoiding use of a tourniquet. During the COVID-19 pandemic, human and logistic resources had to be reorganized, and WALANT ensured resilience in our department to maintain access to surgical care. The objective of the present study was to compare hand function recovery 3 months after surgery for unstable metacarpal or phalangeal fracture under regional anesthesia versus WALANT. From November 2020 to May 2021, 36 patients presenting a metacarpal or phalangeal fracture requiring surgical treatment were included in a single-center study in a university hospital center. Nineteen patients underwent surgery under locoregional anesthesia with tourniquet, and 17 under WALANT. The main endpoint was functional recovery at 3 months on QuickDASH score. Need for complementary anesthesia, surgery duration, analgesic consumption, reintervention rate, and patient satisfaction were also assessed. There was no significant difference between groups in functional recovery at 3 months or on the secondary endpoints. In the COVID-19 context, WALANT proved to be a safe and effective method in hand fracture surgery, ensuring access to surgical care. It should be included in surgical training to optimize day-to-day surgical care and face future crises.
