Comparison Of Dexmedetomidine And Dexamethasone As An Adjuvant To Ropivacaine 0.5 Percentage In Ultrasound Guided Supraclavicular Brachial Plexus Block In Patients Undergoing Upper Limb Surgeries: A Randomised Clinical Trial

Regional anesthesia techniques have advantages including excellent pain control, reduced side- effects, and shortened stay in the post anesthesia care unit. Ultrasound-guided regional blocks are considered safer with better success rates. Supraclavicular block has high efficacy for providing anaesthesia in upper limb surgeries. Ropivacaine with lesser cardiac side effects is the preferred local anaesthetic agent. Dexmedetomidine and Dexamethasone is used to reduce the onset time, prolong the analgesic, and motor blockade effect without the systemic side effects and reduce total dose of local anesthetic requirement. Here, in our study we determine the duration of analgesia and compare the hemodynamic parameters with two different drugs of Dexmedetomidine and Dexamethasone with 0.5% Ropivacaine. We also try to find any adverse reaction to the study drugs. A total of 52 patients undergoing upper limb surgeries will be divided into two groups: Group A and Group B by block randomization. Group D will receive 20 ml of 0.5% Ropivacaine with 2 ml of 20 mcg Dexmedetomidine and Group X will receive 20 ml of 0.5% Ropivacaine with 2 ml of 8mg Dexamethasone. Duration of analgesia, onset of sensory and motor block, time requirement of rescue analgesia will be studied. Hemodynamic parameters and adverse effects will be recorded. The findings and observations made during the entire study will be tabulated, graphically depicted whenever possible, statistically analyzed and inference will be drawn.
