This study compared two common anesthesia techniques used for forearm trauma surgery-Bier's block and the supraclavicular block-to determine which provides better surgical conditions and patient comfort. Among the 66 patients studied, Bier's block produced a much faster onset of numbness and muscle relaxation, but its pain relief wore off quickly. In contrast, the supraclavicular block took longer to take effect but provided significantly longer-lasting postoperative pain relief and greater overall patient comfort, making it more suitable for trauma cases where prolonged anesthesia and smoother recovery are needed. Overall, the study found the supraclavicular block to be the more effective and patient-friendly option for forearm surgeries.
