Suprascapular blocks

No comments

Trends are evolving in decreasing intraoperative and postoperative opioid use.  Therefore, anesthesiologists are constantly learning new regional techniques to help with postoperative pain.  For shoulder surgeries, I’ve moved away from interscalene blocks toward supraclavicular blocks.  I think the interscalene block provides a better block of a total shoulder surgery, however, certain patient comorbidities often make the supraclavicular block a better choice.

Nowadays, it seems that suprascapular blocks are gaining in popularity to supplement the supraclavicular block.
