ClinConnect Summary

This clinical trial is testing a new way to manage pain after shoulder surgery called the "programmed intermittent bolus" (PIB) technique. Unlike traditional methods that slowly deliver pain medication over an hour, the PIB technique gives a larger dose in just a few minutes each hour. The researchers want to see if this method helps patients feel less pain and be more satisfied with their pain control after total shoulder arthroplasty, a surgery typically done for severe shoulder arthritis.

To participate in this study, you need to be an adult in good health (classified as ASA Physical Status I to III) and able to communicate in English. Unfortunately, individuals with certain conditions like a high body mass index (BMI over 40), severe respiratory issues, or chronic pain conditions may not be eligible. If you join the study, you'll receive either the PIB technique or the traditional pain management method, and your pain levels will be closely monitored to see which method works better. This trial is currently looking for volunteers, and your participation could help improve pain management for future shoulder surgery patients.
