Laser guidance for ultrasound-guided radial artery catheterization using smart glasses: a randomized trial
Authors' conclusion
Laser guidance improved the performance of ultrasound-guided radial artery catheterization using smart glasses in users inexperienced in the long axis in-plane approach.
Study context
- Population
- Patients requiring radial artery catheterization under anesthesia; operators relatively inexperienced, unfamiliar with these techniques
- Participants
- 52 patients
- Comparison
- SL vs SO
- SLn = 26
- SOn = 26reference
- Primary endpoint
- Catheterization time
Methodological detailsunblinded
- Unblinded

| Outcome | SL | SO | P value |
|---|---|---|---|
| Number of needle redirectionsLower with SL | 0 (IQR 0–1) | 3 (IQR 1–3) | P < 0.001 |
| Operator satisfaction score (100 = most satisfactory; 0 = unsatisfactory)Higher with SL | 85 (IQR 76–95) | 52 (IQR 44–74) | P < 0.001 |
