Abstract

Wide awake local anaesthesia no tourniquet, also known as WALANT, is the practice of performing surgery under local anaesthetic in the absence of a tourniquet. This technique uses the vasoconstrictive effects of adrenaline and the local anaesthetic effects of lignocaine to establish a Bier block with haemostatic control. Permitting active patient participation intraoperatively, wide awake local anaesthesia no tourniquet surgery improves patient compliance with rehabilitation and yields higher patient satisfaction. With reduced cost and equipment requirements, this method improves accessibility for patients and productivity for healthcare institutions. This is of particular benefit within the current COVID-19 climate, as wide awake local anaesthesia no tourniquet technique provides a means of overcoming restrictions to theatre access and anaesthetic support. This review delves into the current uses of wide awake local anaesthesia no tourniquet surgery, outlining the initial conception of the practice by Canadian surgeons. The advantages and disadvantages are considered, and potential future applications of this technique are discussed.
