The SonixGPS™ needle guidance positioning system provides navigation assistance to facilitate needle handling during ultrasound-guided procedures. Each of 20 inexperienced nurse anaesthetists performed 12 different ultrasound-guided tasks in a porcine phantom. Using both in-plane and out-of-plane approaches, they inserted a needle and made contact with metal rods at depths of 2, 4 and 6 cm. We compared their performances without and with navigation as paired observations. Using the out-of-plane approach, navigation yielded shorter execution times (26 s vs 14 s, respectively; p = 0.01) and fewer needle repositionings (8 vs 3, respectively; p = 0.001). Using the in-plane approach, the needle was more visible with navigation assistance: 24% vs 52% of execution time, respectively (95% CI: 44%-12%; p = 0.0025). Better needle visibility was associated with shorter execution times and fewer needle repositionings. Combining ultrasound-guided techniques with the needle guidance positioning system may reduce tissue manipulation, thus improving patient comfort and safety.
SonixGPS™ 针引导定位系统为超声引导手术中的针操作提供导航辅助。20 名没有经验的护士麻醉师在猪模型上进行了 12 项不同的超声引导任务。他们使用平面内和平面外方法，将针插入并接触到深度为 2、4 和 6 厘米的金属棒。我们将无导航和有导航的情况下的表现作为配对观察进行比较。使用平面外方法，导航使执行时间更短（分别为 26 秒和 14 秒；p = 0.01），重新定位针的次数更少（分别为 8 次和 3 次；p = 0.001）。使用平面内方法，导航辅助下针更可见：分别为执行时间的 24%和 52%（95%CI：44%-12%；p = 0.0025）。更好的针可见度与更短的执行时间和更少的针重新定位有关。将超声引导技术与针引导定位系统相结合，可能会减少组织操作，从而提高患者的舒适度和安全性。
