Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 12
Abstract
Introduction: Many adjuvants with local anesthetic have been used for brachial plexus block prolongation. Dexamethasone when added to local anesthetic, block prolongation with analgesic and anti inflammatory effects have been seen. Material and Methods: 50 randomly selected patients undergoing upper limb surgeries, 20-50 years, ASA grade 1 and 2 grouped in A and B 25 each. And injected with 15 ml of lignocaine-adrenaline + 15 ml of 0.5% Bupivacaine (P) and 2 ml of normal saline in Group A and 2ml of dexamethasone(8mg) instead of saline in Group B. Observation and assessment of onset, duration of sensory and motor blockade, postoperative analgesia duration, nausea and vomiting were done. Graphpad software was used for statistical analysis. Results: There was significantly increase in duration of both sensory and motor block in Group B when compared to Group A. Among Duration of postoperative analgesia in Group A and B was 213.4±34.2 minutes and 642.6±21.2 minutes respectively. Postoperative nausea and vomiting was comparatively more in Group A (30%) compared to Group B (6.6%) respectively. Conclusions: Dexamethasone increases the duration of sensory and motor blockade, prolongs postoperative analgesia and reduces the requirement of other analgesics and incidence of gastrointestinal side effects when added to local anaesthetics in supraclavicular brachial plexus block.
