RESUMO
Peripheral venous as well as arterial punctures have traditionally been performed on the basis of designated anatomical landmarks. However, due to patients' individual anatomy and vessel pathology and depending on individual operators' skill, this landmark approach is associated with a significant failure rate and complication risk. This review comments on the evidence-based recommendations on ultrasound (US)-guided vascular access which have been published recently within the framework of Guidelines on Interventional Ultrasound (INVUS) of the European Federation of Societies for US in Medicine and Biology (EFSUMB) from a clinical practice point of view. Part 1 of the review had its focus on general aspects of US- guidance and on central venous access, whereas part 2 refers to peripheral vascular access.
