Interscalene Block Versus Serratus Posterior Superior Intercostal Plane Block for Arthroscopic Shoulder Surgery

NCT07311096 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 60

No results posted yet for this study

Summary

This randomized controlled trial aims to compare the effectiveness of interscalene (ISB) and serratus posterior superior intercostal plane block (SPSIP) for postoperative analgesia in patients undergoing elective arthroscopic shoulder surgery. The primary outcome is total 24-hour opioid consumption. Secondary outcomes include pain scores, hemidiaphragmatic paresis incidence and severity, duration of analgesia, and changes in lung function. Participants are randomized into ISB or SPSIP groups; blocks are performed under ultrasound guidance. Postoperative pain is managed with patient controlled analgesia(PCA).

Conditions

  • Shoulder Pain

Interventions

PROCEDURE

Interscalene Brachial Plexus Block (ISB)

Patients receive ultrasound-guided ISB before arthroscopic shoulder surgery. 15 ml of 0.25% bupivacaine is injected using a 22 Gauge 50 mm needle with posterior in-plane approach, targeting C5-C6 roots.

PROCEDURE

Serratus Posterior Superior Intercostal Plane Block (SPSIP)

Patients receive ultrasound-guided SPSIP interfascial block in sitting position before surgery. Using a 22 Gauge 10 mm needle, 30 ml of 0.25% bupivacaine is injected between serratus posterior muscle and second rib.
