What You See (Sonographically) Is What You Get: Vein and Patient Characteristics Associated With Successful Ultrasound‐guided Peripheral Intravenous Placement in Patients With Difficult Access

Success was solely related to vessel characteristics detected with US and not influenced by patient characteristics or probe orientation. Successful DIVA was primarily associated with larger vessel, while vessel depth up to >1.6 cm and patient characteristics were unrelated to success. Clinically, if two vessels are identified at a depth of <1.6 cm, the larger diameter vessel, even if comparatively deeper, should yield the greatest likelihood of success.
