Background and Objectives: We evaluated the effect of adding dexamethasone to ropivacaine for supraclavicular brachial blockade. The primary endpoints were the onset and total duration of sensory and motor block, quality of analgesia, and duration of analgesia. Materials and Methods: Eighty patients of age group 20-50 years, scheduled for various elective orthopedic surgeries on forearm and around the elbow under supraclavicular brachial block were divided into two equal groups in a randomized, double-blinded fashion. In group R (n = 40), 30 ml (150 mg) of 0.5% ropivacaine + 2 ml saline; and in group RD (n = 40), 30 ml (150 mg) of 0.5% ropivacaine + 2 ml dexamethasone (8 mg) were given. Motor and sensory block onset times, block durations, quality of intraoperative analgesia, and duration of analgesia were recorded. Results: Demographic data and surgical characteristics were similar in both groups. The sensory and motor block onset time was earlier in group RD as compared to group R (P < 0.05). Sensory and motor blockade durations were longer in group RD than in group R (P < 0.001). Duration of analgesia was longer in group RD than in group R (P < 0.001). The 24 h Visual Analogue Scale (VAS) was more in group R as compared to group RD. The quality of anesthesia was excellent in both the groups. Mean arterial blood pressure levels in groups at 5, 10, 15, 30, 45, 60, 90, 120, and 150 min were statistically insignificant between the two groups (P > 0.05). The mean pulse rate at different time intervals was statistically insignificant between the groups (P > 0.05). Conclusions: Dexamethasone added to ropivacaine for supraclavicular brachial plexus block prolongs the duration of the block and the duration of postoperative analgesia.
