Summary
The authors discuss the use of ultrasound in regional anesthesia. They argue that while ultrasound may have some advantages over traditional methods of nerve localization, such as electrical nerve stimulation, it is not yet clear whether it is safer or more effective.
They also point out that ultrasound requires more training and experience to use effectively, which may limit its adoption.
The authors conclude that ultrasound is a useful tool for training regional anesthesiologists, but it is too early to say whether it will become a standard part of clinical practice.
