This document discusses the general aspects of anatomic and US imaging of vessels, US-guided vascular cannulation techniques, and the identification of local vascular cannulation complications. Proper training should impart the cognitive knowledge and technical skills necessary to perform US-guided cannulation. There is an
increasing body of literature indicating that US-guided vascular access improves success rates and reduces complications, although the quality of the evidence to date remains weak. A gap remains between the existing evidence and guidelines for the use of US in clinical practice. The availability of US equipment and clinical proficiency will more likely influence the role of US-guided vascular access as a standard of care than will future research studies.
