Dexmedetomidine as an adjuvant to 0.75% ropivacaine and 0.5 % levobupivacaine in peripheral nerve stimulator guided supraclavicular brachial plexus block

Abstract

Background: The aim of study was to assess the effect of Dexmedetomidine as an adjuvant to Ropivacaine 0.75% and Levobupivacaine 0.5% in Peripheral Nerve Stimulator guided supraclavicular brachial plexus block. Methods: The study was a single-center, prospective, randomised experiment in which patients were randomly assigned to one of two groups conducted at SVBP Hospital affiliated with LLRM Medical College, Meerut. The study was done in 80 patients undergoing various elective forearm procedures under peripheral nerve stimulator guided brachial plexus block via supraclavicular route. Result: The mean time of onset of sensory block in Group B (Levobupivacaine + Dexmedetomidine) was found to be slight quicker than Group A (Ropivacaine + Dexmedetomidine) and the difference between both groups was found to be significant (p= 0.042) and the duration of analgesia was significantly (p<0.01) prolonged in Group B than Group A. Conclusions: 0.5 % Levobupivacaine and dexmedetomidine combination have quick onset of sensory and motor blockade and a significant prolongation in duration of sensory blockade than 0.75% Ropivacaine and Dexmedetomidine.
