[Real-time ultrasound guided vascular access].

Central venous catheterization and arterial catheterization are common procedures performed perioperatively by anesthetists. The traditional technique of locating surface landmarks was used to assist in vascular access. In patients with anatomical variants or pathological vessel changes it could be difficult or impossible to succeed with this traditional approach. Ultrasound-guided vascular access can improve patient safety in adults and children. Surrounding anatomical structures are visualized and the needle is advanced under continuous observation. Complications can be reduced and success improved. It is mandatory to offer an appropriate ultrasound training programs for physicians using this technique. This article summarizes the literature and describes a practical method of ultrasound-guided vascular access. © Georg Thieme Verlag Stuttgart · New York.
