Abstract
Introduction: Brachial plexus block is a safe and well accepted technique of anaesthesia since it avoids the untoward side effects associated with general anaesthesia, resulting in more favorable outcome along with increased margin of safety. The aim of this study is to establish the role of dexamethasone as adjuvant to levobupivacaine in supraclavicular brachial plexus block.
Material and Method: A randomized single blind controlled study was done on 60 patients of ASA Grade I or II undergoing upper limb surgery. Group A received 30ml of 0.5% Levobupivacaine with 2 ml (8mg) Dexamethasone and group B received 30ml of 0.5% Levobupivacaine with 2 ml of 0.9% normal saline. Onset and duration of both sensory and motor blockade were studied in both the groups.
Results: It was observed that in group A, onset of sensory and motor blockade was faster than group B. Group A had longer duration of sensory and motor blockade in comparison of group B.
Conclusion: It was concluded that the addition of 8mg of dexamethasone to 0.5% levobupivacaine effectively and safely shortens the onset of sensory and motor blockade, increases the duration of sensory and motor blockade without any hemodynamic disturbances.
Keywords: Dexamethasone, Levobupivacaine, nerve stimulator, supraclavicular brachial plexus block.
