What is the purpose of this trial?

This trial tests whether an augmented reality headset (Augmented Reality Heads-up Display) helps doctors better visualize ultrasound images when inserting an IV (a tube that goes into a vein) using an ultrasound machine. Participants are divided into two groups: one uses the traditional ultrasound monitor, and the other uses the headset. The trial aims to determine if the headset improves the ease and accuracy of IV placement. Suitable candidates are adults referred for an ultrasound-guided IV placement who do not require urgent care. As an unphased trial, this study offers a chance to contribute to innovative research that could enhance medical procedures.

Do I have to stop taking my current medications for the trial?

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

What prior data suggests that this augmented reality headset is safe for visualization during ultrasound guided procedures?

Research has shown that augmented reality (AR) systems can improve the accuracy of needle placements, crucial for procedures like inserting an IV catheter. One study demonstrated that using AR to guide needles resulted in a high success rate on the first attempt, with 77.4% of first attempts successful and fluid leakage into surrounding tissue occurring in only 17.7% of cases.

Another study found that AR reduced the time needed for procedures by 27% compared to traditional methods. Thus, AR not only enhances accuracy but also speeds up the process.

Overall, these findings suggest that AR headsets are generally safe and well-tolerated in medical settings. They improve accuracy and save time, with no major safety concerns reported for these procedures. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about using augmented reality (AR) for phlebotomy because it offers a futuristic way to improve how intravenous catheters are placed. Unlike the standard method, where physicians rely solely on ultrasound machine monitors, the AR approach uses a mixed reality headset to superimpose ultrasound images directly in the physician's field of vision. This innovative technique could make it easier to locate veins accurately, potentially reducing the time and discomfort associated with the procedure. The integration of AR technology aims to enhance precision and efficiency, making it a promising advancement in medical procedures.

What evidence suggests that this augmented reality headset is effective for ultrasound-guided catheter placement?

Research has shown that augmented reality (AR) helps healthcare providers place intravenous (IV) catheters more accurately. In this trial, one group of participants will have their IV catheters placed using standard care, while another group will use AR technology. Studies have found that AR technology makes ultrasound images easier to see, leading to more successful IV placements. Specifically, one study showed a 77.4% success rate on the first attempt at placing a catheter with AR tools. Additionally, AR reduces the mental effort needed for trainees, making procedures easier. Overall, AR increases confidence and skill in healthcare settings, making it a promising tool for improving IV insertion techniques. ^{2 4 6 7 8}

• Augmented Reality Heads-up Display

Trial Overview

The study tests if using an augmented reality headset to see ultrasound images helps in guiding the insertion of an intravenous catheter more effectively.

How Is the Trial Designed?

Group I: Augmented Reality Experimental Treatment 1 Intervention

Subjects in this group will have their intravenous catheter placed while the physician uses a mixed reality headset to view the ultrasound images being used to guide the catheter placement.

Group II: Control Active Control 1 Intervention

Subjects in this group will have their intravenous catheter placed using standard of care. The physician will use the monitor on the ultrasound machine only to view the ultrasound images being used to guide the catheter placement.

Published Research Related to This Trial

An augmented reality guidance system for MRI-guided needle placement was developed and tested, showing a targeting error of only 1.09 mm and an overall error of 2.29 mm during procedures, indicating high accuracy.

The system allows physicians to focus on the insertion site without needing special headgear or secondary monitors, enhancing usability and efficiency in MRI suites during procedures like biopsies and arthrography.

A new laboratory validation system has been developed to accurately measure operator performance in needle placement procedures, which is crucial for improving augmented reality (AR) systems used in medical imaging.

Preliminary studies using this system have begun to compare different assistance techniques, such as AR guidance and traditional methods, to assess their accuracy and effectiveness in guiding needle placement.

The augmented reality (AR) system combined with a 1.5-T closed-bore MRI for needle biopsies demonstrated high accuracy, with a mean localization error of just 1.1 mm for virtual targets and successful punctures in all animal trials.

The average procedure time for AR-guided biopsies was 18 minutes, indicating that this method is not only feasible but also efficient for performing biopsies in a clinical setting.

A user study comparing three augmented reality (AR) navigation concepts for needle insertion tasks revealed a clear ranking in effectiveness, indicating that AR can significantly enhance instrument navigation in medical procedures.

Logarithmic scaling of navigation indicators improved accuracy in needle insertion tasks, although participants found it more challenging than linear scaling, highlighting the need for balancing accuracy and user-friendliness in AR navigation designs.

The study evaluated a 3D augmented reality protractor for needle placement accuracy, finding no significant difference in placement errors between two methods (Fix-On-Screen and QR-Tracking), with average errors of 5.6 mm and 6.1 mm respectively.

The Fix-On-Screen method was faster, taking an average of 71 seconds compared to 98 seconds for the QR-Tracking method, making it a more convenient option for clinical use as it does not require additional markers.
