Ultrasound allows for detailed visualization of peripheral nerves. This enables a quick execution of regional anesthesia and reduces the risk of complications. The book demonstrates the procedure for nerve and plexus blocks of the upper and lower extremities using ultrasound and cross-sectional images. Additionally, the authors provide foundational knowledge and introduce classical techniques such as nerve stimulation. New in the second, completely updated edition: sections on complication management, acute pain therapy, among others.
