NCT05834023

Brief Summary

In this study, the investigators will compare two different anesthetic solutions in the infraclavicular block in patients having forearm, wrist, and hand surgery. The solutions will be bupivacaine 0.5% versus bupivacaine 0.25% plus lidocaine 1%, both associated with epinephrine 5 mcg/ml and dexamethasone 4 mg. The main objective of this investigation is to demonstrate that using higher concentrations of bupivacaine alone results in a significant block duration increase compared with the mixture of bupivacaine and lidocaine.
