Ultrasound is a useful adjunct for visualizing vasculature in patients with difficult vascular access
Success is higher in veins that are more superficial and wide
More prone to failure and extravasation; ideally use extra long catheters (>2.5 cm)
Failure of the IV is high when <30% of the catheter length is in the vessel and minimized when >65% of the catheter is intravascular
