Anterior Suprascapular and Axillary vs. Interscalene Block for Analgesia and Diaphragmatic Function in Shoulder Surgery
Comparison of Anterior Suprascapular and Axillary Nerve Block Versus Interscalene Block for Postoperative Analgesia and Diaphragmatic Function in Shoulder Surgery: A Randomized Controlled Trial
Shoulder surgeries are among the most frequently performed orthopedic interventions and are often associated with moderate to severe postoperative pain. In these procedures, effective pain management is crucial for early rehabilitation and patient comfort.
Peripheral nerve blockade is widely used for postoperative analgesia in shoulder surgery. While the interscalene brachial plexus block is considered the gold standard for pain control, it is frequently associated with unintended phrenic nerve blockade, leading to hemidiaphragmatic paresis. To minimize respiratory complications while maintaining effective analgesia, alternative diaphragm-sparing regional anesthesia techniques, such as the combination of suprascapular and axillary nerve blocks, have been introduced.
The aim of this study is to compare the analgesic efficacy and respiratory functions preservation of the ultrasound-guided anterior approach suprascapular combined with axillary nerve block versus interscalene block in patients undergoing shoulder surgery

Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Comparatore attivo: Interscalene Block
After the patients are placed under monitoring and positioned supine, and appropriate field sterilization is achieved, the ultrasound probe will be positioned transversely at the level of the cricoid cartilage (C6) with the head turned to the contralateral side.
Advancing the needle laterally into the interscalene groove between the anterior and middle scalene muscles, 10 mL of local anesthetic (%0.5 bupivacaine ) will be injected between the C5 and C6 nerve roots.
|
Interscalene block will be performed on the patients using 10 mL of 0.5% bupivacaine under ultrasound guidance.
|
|
Comparatore attivo: Combination of Axillary and Anterior Suprascapular Blocks
After the patients are placed under monitoring and positioned supine, and appropriate field sterilization is achieved, the ultrasound probe will be positioned transversely in the supraclavicular fossa with the head turned to the contralateral side.
Advancing the needle in-plane, 5 mL of local anesthetic (%0.5 bupivacaine) will be injected around the suprascapular nerve as it branches anteriorly from the superior trunk of the brachial plexus.
Subsequently, for the axillary nerve block, the patient will be positioned laterally and the ultrasound probe will be placed longitudinally over the posterior aspect of the shoulder.
Advancing the needle into the quadrangular space, 5 mL of local anesthetic (%0.5 bupivacaine) will be injected around the axillary nerve adjacent to the posterior circumflex humeral artery.
|
Combined anterior suprascapular(5 ml) and axillary nerve blocks(5 ml) will be performed on the patients using a total of 10 mL of 0.5% bupivacaine under ultrasound guidance.
