Evaluating the Infraspinatus-teres Minor Block for Pain Relief Before Shoulder Surgery in Adults Aged 21 to 65

What this Trial Is About

Researchers are studying the use of an infraspinatus-teres minor ITM block to improve pain relief before shoulder surgeries. The study aims to see if this block reduces opioid use, enhances overall analgesia, and affects other factors like pain scores, discharge time, and side effects compared to standard general anesthesia. This is a randomized controlled study sponsored by Zagazig University focusing on patients aged 21 to 65 undergoing unilateral shoulder surgery. Participants will be randomly assigned to one of two groups. One group will receive an ultrasound-guided ITM block with local anesthetics including bupivacaine, dexmedetomidine, and dexamethasone before general anesthesia. The other group will receive general anesthesia without the block. The surgery duration is expected to be less than 3 hours, and treatments are administered before surgery. During the study, participants will be monitored for pain using a numerical rating scale at rest and during shoulder movement at several time points up to 24 hours after surgery. Researchers will track opioid consumption, time until first rescue analgesic use, discharge time from the post-anesthesia care unit, side effects of opioids, block-related complications, and patient satisfaction with analgesia. The total participation includes the surgery and 24 hours of postoperative observation.
