A Comparison on Brachial Plexus Block Using Local Anaesthetic Agents With and Without Midazolam

Abstract

Brachial plexus block provide surgical anesthesia and analgesia of upper extremity. Any adjuvant to brachial plexus block have less systemic side effect as well as reduce the total dose local anaesthetics. The midazolam acts on GABA-A receptors in peripheral nerve. The sensory and motor block was significantly faster in our study who received midazolam. This could be local anesthetic properties of midazolam and synergistic action with local anaesthetics. Total 100 patients between ages 10-77 years of either sex of ASA I-III, underwent upper arm surgery were given supraclavicular brachial block with and without midazolam. The onset and duration of sensory block in Gr I (XB) and Gr II (XBM) were significantly different. The onset time for sensory block was significantly prolong and duration of block significantly less compared to Gr II (P<0.05). The onset time for motor block was significantly less and duration significantly higher in Gr II (XBM) as compared to Gr I (XB). Midazolam 50ugm/kg in brachial plexus block speed sensory and motor block with post operative analgesia.
