Freezing nerves during lung transplant may cut pain and morphine use

This pilot study tests a technique called cryo-analgesia, where doctors freeze chest nerves during double lung transplant surgery. The goal is to see if this reduces pain, morphine use, and time in the hospital for people with end-stage COPD. Forty participants will either get the nerve freezing or standard pain treatment, and be followed for one year. It is an early, small study to see if the approach is worth testing in larger trials.
