Brief Summary

Patients undergoing arthroscopic shoulder surgery often experience moderate to severe postoperative pain. Various medical treatments are employed to provide analgesia for these patients. The advancement of regional anesthesia techniques has made possible to both reduce the use of narcotic analgesics and provide long-term pain management benefits. The Serratus Posterior Superior Intercostal Plane Block (SPSIPB) was first described in 2023 by Serkan Tulgar et al. Cadaveric studies and dermatomal analyses in patients have demonstrated its ability to provide analgesia in the back, neck, shoulder, axilla, and lateral thoracic regions. Even though patients undergoing shoulder surgery benefit from the block; once the duration of a single-shot block wears off, they may experience severe pain again. The aim of this study is to investigate the analgesic effects of a single-shot SPSIPB compared to continuous infusion provided by placing a catheter in this region. The hypothesis of this study: In arthroscopic shoulder surgery, the continuous application of the serratus posterior superior intercostal plane block using a catheter will result in lower pain scores, reduced opioid consumption, and improved patient satisfaction compared to single-shot application.

ACTIVE COMPARATOR

Other: Serratus posterior superior intercostal plane block (catheter)

Interventions

Serratus posterior superior intercostal plane block (single-shot) OTHER

30 mL of 0.25% bupivacaine will be injected as single-shot block 20 mins prior to surgery

Group 2: Patients who will receive a single-shot serratus posterior superior plane block

Serratus posterior superior intercostal plane block (catheter) OTHER

In addition to administration of 30 mL of 0.25% bupivacaine prior to surgery, a catheter will be placed in the area to administer bolus of 1 mg/kg of 0.25% bupivacaine every 8 hours postoperatively.

Group 3: Patients who will receive a continuous SPSIB with catheter
