[Ultrasound in interventional pain therapy]

Peripheral nerve blocks are currently performed relatively blind even in the most complex anatomical structures and physicians mostly rely on palpable anatomical landmarks on the surface. Ultrasound has become an indispensable part of the modern medical world and has long since found its way into almost all medical professions. More and more this trend also reaches interventional pain physicians as it is possible to accurately target structures, to track the needle course during the intervention and to visualize the spread of the local anesthetic. Another advantage compared to other radiological techniques is the profound radiation safety for patients as well as for personnel performing the intervention. A deep understanding of anatomy and its correlate in ultrasound images is one of the most important requirements for the successful use of these interventional techniques. Moreover, the safe performance of the procedure depends on the simultaneous hand-eye coordination. Nevertheless, despite the euphoria ultrasound technology should only be used in pain management with sufficient indications.
