Local Anaesthetic Injection Technique for Pain Free Carpal Tunnel Decompression Surgery

Description

This instructional video focuses on the technique of administering local anesthetic for carpal tunnel decompression surgery. The presenter, an experienced surgeon, shares insights from performing over 500 such procedures painlessly. He discusses two primary techniques for local anesthetic infiltration: the Gale technique, where anesthetic is injected just under the skin, and the Altissimi technique, which involves inserting the needle at a 45-degree angle to deliver anesthetic directly into the carpal tunnel. The presenter uses a modified approach, combining elements from both techniques.



The demonstration includes preparation steps, such as drawing up 10 to 12 mls of 1% lidocaine with adrenaline while explaining the importance of minimizing patient discomfort by using a small needle. As he performs the infiltration, he provides commentary on observing skin blanching, confirming effective anesthetic delivery. Key aspects of his technique include careful angle adjustment for needle insertion, aiming for a flat approach rather than a steep angle, and the necessity to inject additional anesthetic into specific areas to prevent potential pain when releasing pressure during the procedure. The overarching goal is to provide a safe and effective anesthetic experience, ensuring patients remain comfortable throughout their carpal tunnel surgery.
