Is this trial a fit for you?

Likely a good fit

Adults classified ASA I–II who are scheduled for arthroscopic shoulder surgery under general anesthesia and who consent to the block are eligible.

Probably not a fit

People on anticoagulant therapy, with bleeding diathesis, local anesthetic allergy, skin infection at the puncture site, or those who decline the procedure are unlikely to receive benefit from this intervention.

What this trial studies

This interventional study applies an ultrasound-guided serratus posterior superior intercostal plane block (SPSIPB), injected at the level of the 2nd–3rd rib, to provide postoperative analgesia after arthroscopic shoulder procedures. Participants are adults with ASA physical status I–II scheduled for arthroscopic shoulder surgery under general anesthesia who will receive standard postoperative analgesia management alongside the intervention. Investigators will record postoperative pain scores, opioid consumption, and opioid-related side effects to compare analgesic efficacy. The block targets the serratus posterior superior muscle to anesthetize lower cervical and upper intercostal nerves using an interfascial injection technique.

Why it matters

Potential benefit: If effective, the block could lower postoperative pain and opioid requirements and reduce opioid-related side effects, facilitating earlier rehabilitation.

How similar studies have gone: The SPSIPB is a novel block first described in 2023 with limited clinical data, though related interfascial chest-wall blocks have shown reductions in postoperative pain and opioid use in other settings.
