Comparing Nerve Blocks for Shoulder Surgery Pain
This study is comparing two ways to manage pain after total shoulder replacement surgery: an Interscalene Catheter and an Exparel Single Shot Interscalene Block. The catheter provides a continuous infusion of pain medication (0.2% ropivacaine) after an initial dose of 0.5% bupivacaine. The single shot block uses a combination of 133 mg Liposomal Bupivacaine (a longer-lasting form of bupivacaine) and 10 ccs of 0.5% Bupivacaine. Researchers want to see which method is better at controlling pain after surgery. You may be able to join if you are having reverse shoulder replacement surgery, are between 18 and 90 years old, and meet other health criteria. The main goal is to measure your pain score one day after surgery. The study is currently unclear on its recruitment status and plans to enroll 56 participants.
- Study design
- This is an interventional study comparing two different pain management procedures for 56 participants. It is not specified if participants are randomly assigned or if the study is blinded.
- What's involved
- You would receive one of two nerve block procedures before your shoulder surgery. Your pain score will be assessed one day after surgery.
- Compensation
- Not stated in the trial record.
- Follow-up
- Your pain will be assessed one day after your surgery.

What this trial measures
- Pain Score Assessed by functional pain score at POD 1The primary outcome will occur at 1 day after surgery date
The primary outcome to be assessed is to determine if there is a quantitative difference in post-operative pain scores as a result of the administration of a interscalene Exparel block versus the administration of an interscalene catheter for shoulder replacement surgery. The functional pain scale is a slightly more quantifiable measure of pain used in a diverse adult population to look at functional ability with pain. The Functional Pain Scale incorporates a "0" to "5" scale, with worsening pain being registered by higher numbers.
