ObjectivesThis study evaluated whether the dynamic needle tip positioning technique increased the success rate of ultrasound-guided peripheral venous catheterization in pediatric patients with a small-diameter vein compared with the static ultrasound-guided technique.DesignRandomized controlled study.SettingSingle institution, Osaka Women's and Children's Hospital.PatientsThe study population included 60 pediatric patients less than 2 years old who required peripheral venous catheterization in the PICU.InterventionsPatients were randomly divided into the dynamic needle tip positioning (n = 30) or static group (n = 30). Each group received ultrasound-guided peripheral venous catheterization with or without dynamic needle tip positioning, respectively. The Fisher exact test, Kaplan-Meier curve plots, log-rank tests, and Mann-Whitney U test were used in the statistical analysis.Measurements And Main ResultsThe first-attempt success rate was higher in the dynamic needle tip positioning group than in the static group (86.7% vs 60%; p = 0.039; relative risk = 1.44; 95% CI, 1.05-2.0). The overall success rate within 10 minutes was higher in the dynamic needle tip positioning group than in the static group (90% vs 63.3%; p = 0.03; relative risk = 1.42; 95% CI, 1.06-1.91). Significantly fewer attempts were made in the dynamic needle tip positioning group than in the static group (median [interquartile range, range] = 1 [1-1, 1-2] vs 1 [1-2, 1-3]; p = 0.013]). The median (interquartile range) catheterization times were 51.5 seconds (43-63 s) and 71.5 seconds (45-600 s) in the dynamic needle tip positioning and static groups, respectively (p = 0.01).ConclusionsDynamic needle tip positioning increased the first-attempt and overall success rates of ultrasound-guided peripheral venous catheterization in pediatric patients less than 2 years old.
