Brief summary
The primary aim of this study is to measure the efficacy of augmented reality technology in ultrasound-guided medical intervention.
Detailed description
BACKGROUND: A significant challenge facing novice physicians is mastering ultrasound(US)-guided procedures, such as central venous catheter (CVC) placement. CVC placements are typically performed on critically ill patients and demand precision and speed. Physicians are often required to switch focus between the ultrasound screen and the patient, memorize multiple images, coordinate hand-eye movements, and interpret 2D images in a 3D context simultaneously. These complexities pose challenges in spatial orientation and impose a considerable cognitive load, affecting both learning and performance. Within the pedagogical landscape, medical educators are exploring the potential merits of Augmented Reality (AR) via head-mounted displays to enhance immersive learning experiences in clinical settings. This study aimed to determine whether AR could ease challenges related to spatial orientation and cognitive overload during this procedure and ultimately enhance skill acquisition for trainees. Intervention: Prior to the commencement of the trial, all participants verified their previous training in ultrasound-guided CVC placement. They also provided their written informed consent. The participants are set to be split into two groups as part of a crossover design: the first group will initially be subjected to the traditional ultrasound-guided CVC placement, whereas the second group will begin with the AR-assisted CVC placement STUDY IMPLICATIONS: Leveraging AR technology in skill acquisition may reduce trainees' cognitive burden and improve trainee efficiency during ultrasound-guided CVC placement procedures..

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Performance of CVC Placement | up to 30 minutes | first pass rate in percent, success/failure rate in percent, number of attempts, number of artery punctures, the number of operator head turns in counts, venous access time (from start to venous access in seconds), lag time (from access ultrasound probe to venous access in seconds), catheterization time (from start to complete catheterization in seconds), total time in seconds. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cognitive load of CVC placement | up to 30 minutes | Cognitive load of CVC placement measured in NASA Task Load Index. The score of the NASA task load index ranges from 0 to 20. A higher score indicates a higher cognitive load. |
