“Cryoanalgesic Preparation” Before Local Anaesthetic Injection for Lid Surgery

Abstract

The study shows that "cryopreparation" by local ice application immediately prior to local anaesthetic injection reduces the sensitivity to the injection by a significant 24.6%. Thus while all the advantages of good analgesia are obtained from the injection, the distressing discomfort is reduced. This study serves as a pilot, in demonstrating a novel method of pain control for lid surgery.
