PROSPECTIVE RANDOMIZED DOUBLE BLINDED COMPARATIVE STUDY OF SUPRACLAVICULAR BRACHIAL PLEXUS BLOCK USING LEVOBUPIVACAINE VERSUS ROPIVACAINE.

Dr. Ashish Gupta, Dr. Gopal Singh Maravi

Abstract


Background: Over decades various local anaesthetic agents have been used for utility of supraclavicular brachial plexus block. Levobupivacaine, an excellent local anaesthetic as well as Ropivacaine, a long-acting local anaesthetic. Methodology: Patients were randomly allocated into two study groups (30 patients each) of all patients  received  30  ml  of  0.5%  injection Levobupivacaine and injection Dexmedetomidine 1µg/kg (LD) while in other group all patients   received 30   ml of 0.5%    injection Ropivacaine and injection Dexmedetomidine 1µg/kg (RD). Results: Time to onset and duration of both sensory and motor block was comparable in two groups (P>0.05). Though mean duration of analgesia was significantly (p<0.005) more for Group-LD when compared to Group-RD. The difference in mean score of VAS in both groups was significantly better for LD-Group at 12, 14 and 16 hour post-operative period (P<0.05) though initially it was comparable.The consumption of Diclofenac as rescue analgesia was significantly higher in Group-RD as compared to Group-LD. Conclusion: Addition of dexmedetomidine along with levobupivacaine for supraclavicular brachialplexus block enhances the duration of postoperative analgesia as well diminished requirement for rescue analgesia in postoperative period compaired to along with ropivacaine.
