Comparing nerve block techniques for shoulder surgery pain relief

This trial is testing four different nerve block techniques — injections of numbing medication delivered using ultrasound guidance near the shoulder nerves — to see which one works best for controlling pain after arthroscopic shoulder surgery. The researchers want to understand which technique causes the least amount of temporary breathing difficulty, gives patients the best recovery, and reduces the need for opioid painkillers after surgery.

Although arthroscopic shoulder surgery is minimally invasive, it often causes moderate to severe pain after surgery that can slow down recovery and rehabilitation. This trial aims to find the best nerve block technique to provide the most effective pain relief while minimizing unwanted side effects.
