This document provides instructions for performing a digital nerve block to anesthetize the distal portion of a finger. It describes injecting 1% lidocaine midway along the finger and fanning the needle dorsally and palmarly to block the digital neurovascular bundle. It notes this technique provides rapid onset anesthesia distal to the distal interphalangeal joint, which is sufficient for most fingertip injuries. It also describes alternatives for blocking a more proximal area or the whole finger.
