The Comparison of Dexmedetomidine to Dexamethasone as Adjuvants to Bupivacaine in Ultrasound-Guided Infraclavicular Brachial Plexus Block in Upper Limb Surgeries

Background The clinical utility of adjuvants with local anesthesia produces an excellent nerve block prolonged duration and faster onset. Brachial plexus is widely used nowadays in patients undergoing upper limb surgery There are several approaches to achieve brachial such as interscalene, supraclavicular, infraclavicular, axillary. objective this study compare the effectiveness dexamethasone dexmedetomidine bupivacaine ultrasound-guided infraclavicular (USG-ICBP) block. Methods A randomized, prospective, double-blind was undertaken on posted for surgeries under Sixty American Society Anesthesiologists (ASA) classes I II were randomly allocated into two groups. Group received 25 mL 0.5% 1.5 (6 mg) dexamethasone, group B 0.75 (75 mcg) along 0.9% normal saline (NS). Student’s t test or Mann-Whitney chi-square statistical analysis. Results onset sensory significantly compared A. In terms block, motor blocks maintained a longer those B. Moreover, postoperative analgesia longer-lasting patients. adverse effects, procedure-related complications failure inadequate comparable across However, drug-related effects more common Conclusion As 75 mcg dexmedetomidine, addition 6 mg adjuvant resulted blocks, analgesia, delayed time first rescue without increasing undue effects. Dexmedetomidine use associated sedation dexamethasone.
