Aims and Objectives: To evaluate the efficacy of tramadol or dexamethasone as an adjuvant to levobupivacaine in ultrasound-guided supraclavicular brachial plexus block in terms of onset time of complete sensory and motor blockade, duration of motor blockade, duration of analgesia, and any complication. Settings and Design: This was a randomized controlled trial conducted in the Department of Anesthesiology, a tertiary care hospital. Materials and Methods: Sixty consecutive patients of the American Society of Anesthesiologists physical status Class I and II who were posted for upper limb surgeries were recruited. Patients were divided into two groups of thirty patients each. Group T (tramadol) received 20 ml of 0.5% levobupivacaine with 100 mg tramadol, and Group D (dexamethasone) received 20 ml of 0.5% levobupivacaine with 8 mg dexamethasone under ultrasound guidance. Sensory and motor block assessment was done every 2 min until the development of complete sensory and motor block till 45 min. Verbal numerical rating scale score was assessed in postoperative ward at regular intervals. Patients were followed up to check for any residual neurological deficits. Results: There was no statistical difference in demographic data between the two groups. The onset time of sensory and motor blockade shows no significant difference between groups. The mean time duration of motor blockade in Group T was 764.63 min and for Group D was 1150.27 min which was statistically significant (P < 0.05). The duration of analgesia in Group D was 1300.83 min and in Group T was 820.47 min which was statistically significant (P < 0.05). Side effects such as nausea, vomiting, pruritis, hypoxemia, and long-term neurological deficits were not reported in any of the patients in either group. Conclusion: Dexamethasone 8 mg as an adjuvant to 0.5% levobupivacaine for supraclavicular brachial plexus block using ultrasound guidance increases the duration of analgesia in comparison to 100 mg tramadol and provides excellent postoperative pain-free period without any neurological deficits.
