Anterior Suprascapular and Axillary vs. Interscalene Block for Analgesia and Diaphragmatic Function in Shoulder Surgery
Turkey (Türkiye)70 participantsStarted 2026-08-06
Plain-language summary
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

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
