Abstract

Introduction: Regional anaesthesia techniques are very successful in alleviating pain during and after various surgical procedures. During upper extremity surgery Supraclavicular Brachial plexus block is commonly administered. Various methods had been tried to extend the period of analgesia intra and post-operative. When dexmedetomidine along with Bupivacaine is used the anaesthesia and the analgesia requirements are reduced to a large extent.
Aims and Objectives: The study was carried out to study the effect of adding Dexmedetomidine with Bupivacaine in the supraclavicular brachial plexus block.
Material and Methods: In the present randomized, double blind and prospective study on 60 cases of ASA grade 1 and grade 2, within in the age group between 18-60 years from a tertiary care medical college was conducted between Jan 2015 - Dec 2015. Group B (control): received 0.25% Bupivacaine while Group D (case): received 0.25% Bupivacaine plus 30µg Dexmedetomidine .Various parameters were studied.
Results: It was found that onset of sensory block was early in Dexmedetomidine group cases. It was also observed that motor block onset was early in dexmedetomidine group and statistically highly significant. The period of sensory and motor block was significantly extended in group (D) in comparison to that of group (B). The analgesia duration was also prolonged.
Conclusion: From the results we concluded that addition of Dexmedetomidine to Bupivacaine provide early onset of sensory and motor block and prolongs blockade and duration of analgesia.
