Comparison of usg guided technique and nerve stimulator technique in supraclavicular brachial plexus block in upper limb surgeries

Abstract

ABSTRACT INTRODUCTION: The supraclavicular technique to blocking the brachial plexus is thought to be the simplest and most successful. The traditional method of employing paresthesia to locate the nerve cluster by anatomical landmarks has been linked to a higher failure rate and nerve damage. The peripheral nerve stimulator (PNS) improves brachial plexus localization by locating nerves using a low-intensity electric current (up to 2.5 mA) for a short duration (0.05–1 ms) with an insulated needle to obtain a defined response of muscle twitch or sensation and injecting local anaesthetic solution close to the nerve. However, this method did not minimise the danger of harm to nearby structures. The use of ultrasonography (USG) to locate the brachial plexus has changed the field of regional anaesthesia forever. The expense and knowledge necessary, however, are the limiting elements. The purpose of this research was to compare the two procedures in terms of process time, block properties, and complication rate.
