ClinConnect Summary

This clinical trial is studying two different methods of pain relief for patients undergoing shoulder arthroscopy, which is a type of surgery on the shoulder. The researchers want to find out which method works better and is safer: the Interscalene block (ISB) or the Infraspinatus-Teres minor (ITM) block. Both techniques involve using ultrasound to guide the injection of anesthetic medication to help manage pain after the surgery.

The trial will include 46 patients aged between 20 and 70 who are generally healthy and scheduled for this type of surgery. Participants will be randomly assigned to one of the two groups before they receive general anesthesia. They will be monitored for pain relief, how long the pain relief lasts, any side effects, and their overall satisfaction after the surgery. This information will help doctors understand which pain management technique might be better for patients in the future. If you or a family member are interested in participating, you would need to meet specific health criteria and give your consent to join the study.
