Ultrasound-guided peripheral intravenous access placement for children in the emergency department.

UMIN000014730 What is Known: • Children experience a low success rate (about 60% with 1 attempt and about 90% with 4 attempts) for IV access placement. • Ultrasound guidance may lead to a decreased number of attempts and shorter procedural time with comparable overall IV success rate. What is New: • Ultrasound-guided IV placement (a real-time, dual operator method) actually led to a significantly lower IV success rate than the conventional technique in children in the emergency department. • Our result warrants further trials to determine the precise population who benefits from ultrasound guidance.
