Background: Regional nerve blocks are crucial for intraoperative and postoperative pain management, reducing complications linked to general anesthesia. The purpose of this study is to compare the effects of dexamethasone dosages of 2mg & 6mg on sensory & motor block completion periods as well as post-operative analgesic duration in infraclavicular blocks for upper-limb procedures. Methods: Infraclavicular brachial plexus block guided by USG was administered to 34 ASAI and II patients, with 17 patients in each group. 25 ml of 0.5% levobupivacaine and 2 mg dexamethasone were administered to Group A. For the block, Group B received 25 ml of 0.5% levobupivacaine combined with 6 mg dexamethasone. The analysis did not include three of the unsuccessful blocks. After the brachial plexus block, vital parameters were recorded every at 0, 120,150,180, 210 and 240 mins. Postoperatively vitals were recorded at 12 hours, 24 hours and 36 hours. The patient was monitored until the motor and sensory block had regressed completely. Results: The study found that demographic variables and hemodynamic parameters were non-significant in both groups. The mean duration of motor block in group A (2mg) was 1069.38 minutes, significantly lower than group B (6mg) with 1294.07 minutes. Additionally, the mean duration of analgesia in group A (2mg) was 1117.19 minutes, significantly shorter than group B (6mg) with 1418.13 minutes. Conclusion: The study suggests that a 2mg dosage of dexamethasone when combined with 0.5% levobupivacaine, may be a more effective option for infraclavicular brachial plexus blocks due to its ability to provide effective analgesia.
