Ultrasonographic Guidance to Improve First-Attempt Success in Children With Predicted Difficult Intravenous Access in the Emergency Department: A Randomized Controlled Trial

摘要

Study objective: We determine whether ultrasonographically guided intravenous line placement improves the rate of first-attempt success by 20% for children with predicted difficult intravenous access. Secondary objectives included determining whether ultrasonographically guided intravenous line placement reduces the attempt number, improves time to access or parental satisfaction, or affects intravenous line survival and complications.
