Brief Summary

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.

Conditions

Augmented Reality; Virtual Reality

Keywords

ultrasound-guided procedure; nerve block

Outcome Measures

Primary Outcomes (3)

• Procedure success rate (Primary Block)

  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

  Document the block result pre-operatively (at least 30 min following block completion), or within one hour upon arriving to PACU

• Post-operative opioid consumption

  Morphine milligram equivalents (MME) will be measured post-operatively

  12 hours after surgery

• Post-operative pain scores

  Trend pain scores on 11-point NRS scale (from 0 to 10) following the procedure

  12 hours after surgery

Secondary Outcomes (4)

• Clinician satisfaction

  Within 24 hours of block completion

• Procedure duration

  During the procedure

• Needle pass/redirection

  During the procedure

• Needle visualisation

  Within 24 hours of block completion

Study Arms (1)

AR/VR

EXPERIMENTAL

AR/VR technology for ultrasound-guided procedures.

Device: Ultrasound-guided procedure using AR/VR technology

Interventions

Ultrasound-guided procedure using AR/VR technology DEVICE

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.
