USG guided brachial plexus block: A comparison of analgesia duration using Bupivacaine with and without Dexamethasone as adjuvant.

Brachial plexus block is one of the preferred techniques for anaesthesia for upper limb surgeries. The advantage being that of analgesia lasting even after the anaesthesia with motor block wears off. Many adjuvants have been explored for co-administration along with the local anaesthetic to prolong this period. Each of these adjuvants has its own side effect profile, with this study we will attempt at understanding the analgesic effect and duration and also the side effect profile by comparing blood sugar levels and duration of motor blockade.
