Comment éviter les accidents de l'anesthésie locorégionale sous échoguidage ?

Thanks to ultrasound guidance, the risk of intravascular needle placement, intravascular or intraneural injection is decreased, providing a good expertise in anatomy. Ultrasound guidance also allows to reduce the volume of the local anaesthetic injection, and to improve patient' comfort. Safety is improved by direct or indirect visualisation of the needle tip, of the neuronal target and of the solution spreading. Block performance under ultrasound guidance requires sticking to hygiene principles especially when a catheter is placed to prevent septic complications.
