The clinical economics of ultrasound-guided procedures
semanticscholar(2011)
摘要
Many physicians use landmark (or “blind”) techniques to perform needle-related procedures at the point of care, such as line placements, aspirations, injections, or other interventions. Because landmark techniques do not account for human anatomical variation or enable the physician to see the area of interest, they can increase the number of attempts, as well as the risk of complications and sub-optimal outcomes.
