This study looked at whether adding a nerve block in the armpit to the standard shoulder block can reduce pain and opioid use after total shoulder replacement. Twelve adults having shoulder replacement surgery received both blocks. Researchers measured recovery room time, pain scores, and how much opioid medication they needed.
