Randomized Controlled Trial Comparative StudyClonidine, but not Dexamethasone, Prolongs Ropivacaine-Induced Supraclavicular Brachial Plexus Nerve Block Duration.
Ultrasound-guided supraclavicular brachial plexus block (USSB) provides excellent postoperative analgesia after upper extremity surgery. Dexamethasone and clonidine have been added to local anesthetics to enhance and prolong the duration of analgesia. ⋯ The results demonstrated that clonidine significantly prolongs the duration of ropivacaine effects for the postoperative analgesia in patient underwent upper arm surgeries.
