Trial Summary

What is the purpose of this trial?

Patients with difficulty intravenous access frequently have delay of care in emergency departments because Emergency Department (ED) personnel could not establish intravenous (IV) access for diagnostic blood test or treatment. The ultrasound machine or near-infrared devices have been used to improve this situation but no study has ever compared which machine is more efficient. This study is designed to investigate whether the ultrasound or Vein Viewer, which is a near-infrared device, is more efficient.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Veinviewer, Zonare for difficult IV access?

Research suggests that near-infrared venous imaging, like the VeinViewer, may be more useful than ultrasound for novices in obtaining difficult venous access. However, for experienced nurses, the VeinViewer might not improve success rates in children with difficult IV access.12345

Is the use of VeinViewer and ultrasound for difficult IV access safe for humans?

The studies reviewed do not report any safety concerns or adverse events related to the use of VeinViewer or ultrasound for difficult IV access, suggesting they are generally safe for human use.12567

How does the VeinViewer treatment differ from other treatments for difficult IV access?

The VeinViewer is unique because it uses near-infrared light to project an image of veins onto the skin, helping healthcare providers visualize veins that are difficult to see or feel, especially in children and those with challenging venous access. This differs from ultrasound, which uses sound waves to create images of veins and is more commonly used by experienced practitioners.12346

Eligibility Criteria

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.

Inclusion Criteria

Patients who fail inspections for visible or palpable veins
I am asking for an ultrasound-guided IV.
I know my name, where I am, the date, and the current president.

Exclusion Criteria

I need immediate medical intervention due to unstable blood pressure or heart rate.
I am under 18 years old.
I am able to understand and consent to my treatment.

Treatment Details

Interventions

  • Veinviewer
  • Zonare
Trial Overview 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.
Participant Groups
2Treatment groups
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.
