This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether a newer combination of two targeted numbing injections works as well as the standard single injection for shoulder surgery pain relief — while causing fewer breathing problems. Doctors are comparing the traditional interscalene block with a two-part approach using suprascapular and infraclavicular blocks. The goal is to find a method that relieves pain effectively without affecting how well your diaphragm (the muscle that helps you breathe) works after surgery.
The standard numbing injection for shoulder surgery is very effective at blocking pain, but it often temporarily paralyzes part of the breathing muscle, which can be concerning for older people and those with lung problems. This trial is exploring whether the two-injection combination can provide the same pain relief while keeping your breathing function intact.

You will be randomly assigned to receive one of the two numbing techniques before your shoulder surgery. Both methods use ultrasound guidance (similar to imaging used during pregnancy) to place the injections precisely. Your diaphragm function will be checked with ultrasound before and after the numbing is done. After surgery, the research team will track your pain levels, how much pain medication you need, your breathing function, and your overall satisfaction — typically through the hospital stay and follow-up visits.
