Study Summary

This trial will compare the ultrasound machine and the Vein Viewer, a near-infrared device, to see which is more efficient in helping patients with difficult intravenous access in emergency departments.

Who is the study for?
This trial is for patients who have trouble getting IVs placed because their veins are hard to see or feel. They must be able to identify themselves, the hospital, the date, and the current president. Only English speakers who can consent and aren't intoxicated or confused can join.Check my eligibility
What is being tested?
The study compares two devices used to help insert IVs in difficult cases: an ultrasound machine (Zonare) and a near-infrared device called Veinviewer. It aims to find out which one is more efficient in an emergency department setting.See study design
What are the potential side effects?
There may not be direct side effects from using Zonare or Veinviewer as they are non-invasive imaging technologies; however, discomfort or complications related to multiple attempts at IV insertion might occur.

Experimental Treatment
Group I: ZonareExperimental Treatment1 Intervention
108 patients are randomized to receive the intervention of using ultrasound machine (Zonare ZS3 machine) for IV cannulation. These patients will first undergo IV cannulation with assistance of the ultrasound machine.
Group II: VeinviewerExperimental Treatment1 Intervention
108 Patients are randomized to receive the Intervention of using the Veinviewer Flex machine for IV cannulation. These patients will first undergo IV cannulation with assistance of the Veinviewer Flex machine.
