Abstract

Ultrasonography is an easy, quick and noninvasive technique, enabling dynamic real time interaction with the clinical examination. Technological advances have made it reality to obtain high-resolution dynamic images, which may even make ultra-sonography a better alternative to other ulternative devices. Using ultrasound for regional anesthesia allows clinicians to visualize their needle and target structures more clearly and confidently, while also avoiding structures in the needle’s path, potentially decreasing complications; such as nerve injury, vascular injury and tissue damage.
