Comparison of the Postoperative Analgesic Efficacy of SPSIPB and ISBPB

January 19, 2026 updated by: Atakan Sezgi, Ankara Etlik City Hospital

Comparison of the Postoperative Analgesic Efficacy of Serratus Posterior Superior Intercostal Plane Block and Interscalene Brachial Plexus Block in Shoulder Arthroscopy

Shoulder arthroscopy is one of the common surgical procedures performed today. After shoulder surgery, providing adequate analgesia is necessary for both the comfort of the patient and the ability to perform the necessary post-operative rehabilitation exercises early and regularly.

Nerve blocks reduces opioid consumption in the postoperative period by providing better pain control and therefore has advantages such as fewer side effects and less risk of pulmonary and cardiac complications.

In this study; it was aimed to compare the analgesic effectiveness of interscalene brachial plexus block and serratus posterior superior intercostal plane block, with each other and with the control group in the postoperative period in patients who underwent shoulder arthroscopy.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Interscalene brachial plexus block
After the patients are monitored and in the supine position, after appropriate field sterilization, interscalene brachial plexus block will be performed on the patients using 30 ml of local anesthetic solution (0.25% bupivacaine) under ultrasound guidance. In the intraoperative period, intravenous analgesics (dexketoprofen 50 mg, tramadol 100 mg) will be given.
Procedure: Interscalene brachial plexus block

Interscalene brachial plexus block will be performed on the patients using 30 ml of local anesthetic solution (0.25% bupivacaine) under ultrasound guidance.

Additionally, in the postoperative period a paracetamol dose of 1 g every 8 hours and a dexketoprofen dose of 50 mg twice daily were administered iv for multimodal analgesia.
Active Comparator: Group without peripheral nerve block
After the patients are monitored, they will be operated under general anesthesia without peripheral nerve block and intraoperative intravenous analgesics (dexketoprofen 50 mg, tramadol 100 mg) will be given.
Procedure: Group without peripheral nerve block
In the postoperative period a paracetamol dose of 1 g every 8 hours and a dexketoprofen dose of 50 mg twice daily were administered iv for multimodal analgesia.
Active Comparator: Serratus posterior superior intercostal plane block
After the patients are monitored and in the sitting position, after appropriate field sterilization, a serratus posterior superior intercostal plane block will be performed on the patients using 30 ml of local anesthetic solution (0.25% bupivacain) under ultrasound guidance. In the intraoperative period, intravenous analgesics (dexketoprofen 50 mg, tramadol 100 mg) will be given.
Procedure: Serratus posterior superior intercostal plane block

Patients will undergo serratus posterior superior intercostal plane block using 30 ml of local anesthetic solution (0.25% bupivacaine) under ultrasound guidance.

Additionally, in the postoperative period a paracetamol dose of 1 g every 8 hours and a dexketoprofen dose of 50 mg twice daily were administered iv for multimodal analgesia.
