Topical Lidocaine for Digital Nerve Block Pain

Overview

The goal of this clinical trial is to determine whether topical lidocaine spray applied to the wound before digital nerve block can reduce injection-related pain in patients with finger lacerations. The study will also evaluate whether topical lidocaine spray affects the success of the nerve block. The main questions it aims to answer are: Does topical lidocaine spray reduce pain during digital nerve block injection? Does topical lidocaine spray improve first-pass success of the digital nerve block? Researchers will compare topical lidocaine spray with a placebo spray to determine whether lidocaine provides better pain control during the procedure. Participants will: Receive either topical lidocaine spray or placebo spray applied to the wound before the digital nerve block. Undergo a standard digital nerve block with lidocaine. Rate their pain during the procedure. Be assessed for block success, procedure duration, satisfaction, willingness to undergo the procedure again if needed, and adverse events.

This prospective, randomized, double-blind, placebo-controlled, multicenter clinical trial evaluates the effect of topical lidocaine spray on pain associated with digital nerve block in patients presenting with finger lacerations. Participants are randomized to receive either topical lidocaine spray or placebo before a standardized digital nerve block. Patients, clinicians performing the block, and outcome assessors are blinded to treatment allocation. In addition to procedural pain and first-pass block success, procedure duration, patient satisfaction, willingness to undergo the procedure again, and adverse events are evaluated.
