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.
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.
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).
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.
最近有几种头戴式显示器可用于医疗领域。由于头戴式显示器能够在不改变视线方向的情况下提供可视化信息，因此超声引导下中心静脉置管术可能会进行得更快且更安全。其中一种头戴式显示器，即近眼显示器（NED；NED原型产品，日本建伍JCV公司）在超声引导下中心静脉置管术中进行了测试。
11名经验丰富的麻醉医生在训练模拟器上分别使用NED和对照方法（不使用NED）进行中心静脉置管。用摄像机记录超声实时图像和操作视野，并进行分析以确定操作时间、成功率和无意穿破静脉后壁的发生率。
使用NED时，虽然中心静脉置管所需时间与标准方法相似（对照组为31.3±8.7秒，NED组为30.2±7.9秒，P = 0.61），但无意穿破后壁的情况发生率往往较低（对照组为21%，NED组为9%，P = 0.17）。
由于NED可帮助操作者在不移动视线的情况下同时看到穿刺部位和超声图像，NED可能是超声引导下中心静脉置管术中一种有前景的辅助设备。
