Because head-mounted display can provide the visualized information without moving direction of eye- sight, ultrasound guided central venous cannulation might be performed more quickly and safer” Kasuya et al (2018).
BACKGROUND: Recently several types of head- mounted displays are available for use in the medical field. Because head-mounted display can provide the visualized information without moving direction of eye- sight, ultrasound guided central venous cannulation might be performed more quickly and safer. One of the head-mounted type displays, Near-Eye Display (NED; NED prototype product, JCV Kenwood, Japan) was tested in ultrasound guided central venous cannulation.
METHODS: Eleven experienced anesthesiologists per- formed central venous cannulation on the training sim- ulator with NED and with control method (without NED). Ultrasound real time image and operating field were recorded by video camera and analyzed to iden- tify procedure time, success rate and incidence of unintentional posterior venous wall penetration.
RESULTS: With NED, although time required for cen- tral venous cannulation was similar to the time with standard method (31.3 ± 8.7 sec with control and 30.2 ±7.9 sec with NED, P=0.61), unintentional posterior wall penetration tended to occur less frequently (21% with control and 9% with NED, P=0.17).
DISCUSSIONS AND CONCLUSIONS: As NED can help practitioners to have both insertion field and ultra- sound image visible without moving eyesight, NED might be a promising assist device for the ultrasound guided central venous cannulation.
