Digital injuries are among the most common presentations to the emergency department. In order to sufficiently examine and manage these injuries, adequate, prompt, and predictable anaesthesia is essential. In this trial, we aim to primarily compare the degree of pain and anaesthesia onset time between the two-injection dorsal block technique (TD) and the single-injection volar subcutaneous block technique (SV). Further, we describe the temporal and anatomical effects of both techniques for an accurate delineation of the anesthetized regions. A single-centre prospective randomized controlled trial involving patients presenting with isolated wounds to the fingers requiring primary repair under local anaesthesia. Patients were randomized to either the SV or TD blocks. The primary outcome was procedure-related pain (Numerical Rating Scale). Further, we assessed the extent of anaesthesia along with the anaesthesia onset time.Background
