Prospective Randomised Study To Compare Inj Dexmedetomidine And Inj Clonidine As Adjuvant To Bupivacaine Used For Ultrasound Guided Subclavian Perivascular And Axillary Block In Upper Limb Surgeries

Background: Ultrasound continues to grow in popularity as a method of nerve localization and it has the advantage of allowing real time visualization of the plexus , pleura and vessels along with the needle and local anaesthetic spread. [4] So this study intends to compare efficacy and safety of Inj.clonidine and Inj.Dexmedetomidine as adjuvant to local anaesthetic for USG guided subclavian perivascular and axillary block in upper limb surgeries. Materials and Methods: We conducted this study as a prospective randomized study. A total of 70 adult patients were randomly selected who fulfilled the inclusion criteria. They were divided into groups and study was conducted. Results: In this study, we measured the results of each drug by its action on onset and peak of sensory and motor blockade and duration of blockade. Conclusion: From our study we conclude that both Clonidine and Dexmeditomidine with local anaesthetics promote satisfactory anaesthesia for upper limb surgeries. Onset and duration sensory blockade of clonidine group is faster and duration of sensory blockade is more than dexmeditomidine group as adjuvant to local anaesthetics in USG guided subclavian pervascular block plus axillary block.
