Augmented Reality/Virtual Reality (AR/VR) for Ultrasound-guided Medical Procedures
What this study is about
The study seeks to assess the effectiveness of incorporating augmented reality (AR) or virtual reality (VR) technology into ultrasound-guided medical procedures such as regional anesthesia and line placement. By utilizing AR/VR devices, the investigators will improve the ergonomics when using ultrasound to guide procedures.
View original scientific description
The study seeks to assess the efficacy of incorporating augmented reality (AR) or virtual reality (VR) technology into ultrasound-guided medical procedures such as regional anesthesia and line placement. By utilizing AR/VR devices, the investigators will improve the ergonomics when using ultrasound to guide procedures. The aims are to enhance visualization of anatomical structures and improve procedural accuracy for clinicians. The study aims to evaluate the feasibility, and effectiveness of integrating AR/VR technology into ultrasound-guided procedures, with the ultimate goal of improving patient outcomes.
Interventions
DEVICE
Ultrasound-guided procedure using AR/VR technology
Participants will receive the intervention, which involves utilizing AR/VR technology during ultrasound-guided procedures (e.g., regional anesthesia, line placement). All participants will receive standard pre- and post-block or line care as they normally would for the ultrasound-guided procedure.
Primary outcome measures
Procedure success rate (Primary Block)
Time frame: Document the block result pre-operatively (at least 30 min following block completion), or within one hour upon arriving to PACU
Document the block result in pre-op, if feasible, or PACU by testing sensory (cold spray) and motor function on all nerves covered by the block
Post-operative opioid consumption
Time frame: 12 hours after surgery
Morphine milligram equivalents (MME) will be measured post-operatively
Post-operative pain scores
Time frame: 12 hours after surgery
Trend pain scores on 11-point NRS scale (from 0 to 10) following the procedure

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
