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.

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.

Participant Groups

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.

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.
