Ultrasound vs Veinviewer for Difficult IV Access
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine the more effective method for inserting an IV in patients with difficult veins. It compares two devices: the Vein Viewer, which uses near-infrared light to enhance vein visibility, and the Zonare ultrasound machine. Quick IV access can be critical in emergencies, making this research important. Individuals who typically struggle with IV insertion and can recognize basic details about themselves and their surroundings may be suitable candidates for this trial. As an unphased trial, it offers a unique opportunity to contribute to the improvement of emergency care techniques.
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 prior data suggests that these devices are safe for IV access?
Research shows that both the VeinViewer and ultrasound methods for finding veins are generally safe. Studies on the VeinViewer indicate it doesn't add extra risks beyond those expected with regular IV procedures. The usual risks, such as bleeding, bruising, pain, and infection, remain similar to those with standard IV placement.
Similarly, using ultrasound to guide IV placement also appears safe. Studies have not reported any specific safety issues or problems when using ultrasound for difficult IV access, suggesting that patients tolerate the technique well.
Overall, both the VeinViewer and ultrasound methods seem to be safe options for assisting with difficult IV access, without adding significant risk beyond a standard IV procedure.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it compares two advanced techniques, Veinviewer and Zonare, for improving IV access in patients with difficult veins. Veinviewer uses near-infrared light to create a real-time image of the veins on the skin, helping healthcare providers find the best spot for IV insertion. Zonare, on the other hand, employs ultrasound technology to visualize veins beneath the skin, providing a clear view for accurate needle placement. Both methods aim to make IV insertions more successful and less painful, potentially reducing the number of attempts needed compared to traditional methods.
What evidence suggests that this trial's devices could be effective for improving IV access?
This trial will compare the effectiveness of the VeinViewer and the Zonare ultrasound machine for difficult IV access. Studies have shown that the VeinViewer, which uses near-infrared light, can improve the success rate of first-attempt IV insertions compared to traditional methods. One study found a significant improvement in success rates, while another study noted that the VeinViewer did not necessarily aid experienced nurses. Conversely, research suggests that ultrasound, such as the Zonare machine, is often the best approach for difficult IV insertions. An observational study found that ultrasound helped avoid more invasive procedures in 85% of patients with challenging IV access. Overall, both devices show promise, but their effectiveness can depend on the user's experience and the specific situation.16789

Are You a Good Fit for This Trial?
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

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.

Treatment groups
Experimental Treatment
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.
