Diaphragmatic Effects of Combined Infraclavicular Brachial Plexus Block and Suprascapular Nerve Block
Turkey (Türkiye)61 participantsStarted 2025-02-22
Plain-language summary
This prospective observational study was conducted to evaluate the effects of a combined infraclavicular brachial plexus block and anterior suprascapular nerve block on diaphragmatic function in patients undergoing arthroscopic shoulder surgery. A total of 61 adult patients were enrolled in the study. Diaphragmatic excursion was assessed using ultrasonography both prior to block administration and 30 minutes following the procedure during normal and deep breathing. The primary objective was to assess changes in diaphragmatic excursion and determine the incidence of hemidiaphragmatic paralysis associated with this combined block technique. Secondary outcomes included block performance time, duration of postoperative analgesia, the need for additional intraoperative sedation or analgesia, the occurrence of adverse events, and levels of patient and surgeon satisfaction. The study sought to determine whether this regional anesthesia approach could provide effective anesthesia and analgesia while minimizing impairment of diaphragmatic function.

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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
