Comparison of Perioperative Analgesic Efficacy and Quality of recovery on addition of lignocaine with adrenaline to Levobupivacaine in Ultrasound Guided Supraclavicular Block for Upper Limb Orthopaedic Surgeries: A Randomised Control Study

Current study is to research the effect of lignocaine as an adjuvant to levobupivacaine for advancement of scientific knowledge.

The aim of this study is to compare the perioperative efficacy and recovery quality of ultrasound guided supraclavicular block  administered using levobupivacaine with or without lignocaine with adrenaline for conduct of upper limb surgeries. Patients will be randomly divided into two groups (LLB and LL) with 40 patients in each group. The nerve bundle will be identified and infiltrated with the local anesthetic after negative aspiration for blood and no intraneural spread as visualized with ultrasound. Group LB will receive  28 mL of 0.5% levobupivacaine and 2 mL of normal saline  while the Group LLB will receive 14 ml of 0.5% levobupivacaine,14 ml of lignocaine with adrenaline  and 2 ml of normal saline making a total 30 ml of anestheticsolution. Patients will be observed for onset and duration of spinal and motor blockade in both the groups. The hemodynamic changes and side effects if any, would also be noted and compared amongst two groups. Postoperative analgesia requirement with rescue analgesia using injection Paracetamol 1gm intravenously.
