Abstract

Background

The objective of this study was to determine whether gaze patterns could differentiate expertise during simulated ultrasound-guided Internal Jugular Central Venous Catheterization (US-IJCVC) and if expert gazes were different between simulators of varying functional and structural fidelity.

Methods

A 2017 study compared eye gaze patterns of expert surgeons (n = 11), senior residents (n = 4), and novices (n = 7) during CVC needle insertions using the dynamic haptic robotic trainer (DHRT), a system which simulates US-IJCVC. Expert gaze patterns were also compared between a manikin and the DHRT.

Results

Expert gaze patterns were consistent between the manikin and DHRT environments (p = 0.401). On the DHRT system, CVC experience significantly impacted the percent of time participants spent gazing at the ultrasound screen (p < 0.0005) and the needle and ultrasound probe (p < 0.0005).

Conclusion

Gaze patterns differentiate expertise during ultrasound-guided IJCVC placement and the fidelity of the simulator does not impact gaze patterns.

Highlights

•	Expert gaze patterns are consistent between simulators of varying structural and functional fidelity.
•	Gaze patterns differentiate expertise during ultrasound-guided CVC placement.
•	Novices spend significantly more time tracking tools than experts and senior residents.
•	Gaze training may complement skills training in image-guided surgical procedures.
