ClinConnect Summary

This clinical trial is studying two different methods of pain management for patients undergoing total shoulder replacement surgery, also known as reverse shoulder arthroplasty. The researchers want to compare the effectiveness of a single injection of a pain-relieving medication called Exparel with a continuous pain relief method using an interscalene catheter. The goal is to see which method provides better pain control after surgery.

To be eligible for this trial, participants should be at least 18 years old and under 90, and they must be scheduled for this specific shoulder surgery. They also need to be in good health overall, which is classified as being in ASA class I, II, or III (these classes indicate how healthy a person is before surgery). Potential participants should be able to understand and provide consent for their involvement. It's important to note that certain medical conditions or treatments, like significant lung issues, chronic use of certain pain medications, or pregnancy, may disqualify someone from participating. Those who join the trial can expect to receive either the single injection or the catheter for pain relief, and they will be monitored closely to see how well their pain is managed after the surgery.
