Abstract

BACKGROUND

Clinicians apply the ultrasound-guided technique to securely access blood vessels and peripheral nerves in various medical conditions. Acquiring the in-plane technique for this purpose is challenging for novice medical practitioners.

OBJECTIVES

We aimed to assess whether a needle guidance device improves the needle puncture speed and the quality of the needle visualization in the ultrasound-guided in-plane technique on both horizontal and inclined surfaces by medical students, compared with freehand.

METHODS

We set the following three ultrasound-guided techniques: the needle direction along the visual axis in the conditions of the horizontal plane of the phantom, the plane inclined to the right at 45 degrees, and the plane inclined to the left at 45 degrees. Right-handed 20 medical students were asked to implement ultrasound-guided punctures with and without a needle guidance device (SIVA guide™, Fuji-Medical Co., Tokyo, Japan) in the three conditions.

RESULTS

Under all puncture settings, the time it took to reach the set success point of the target in the ultrasound-guided punctures with the needle guidance device was less than (up to 4.14 sec (median); <0.01) in the punctures without the device. The needle image quality score and the participants' self-assessment of the procedure difficulty score in the punctures with the needle guidance device were better than those without it.

CONCLUSION

A needle guidance device appears to improve the needle puncture speed and the quality of the needle visualization in the ultrasound-guided in-plane technique on both horizontal and inclined surfaces by novice medical students, compared with freehand.

摘要

背景

临床医生在各种医疗情况下应用超声引导技术来安全地穿刺血管和周围神经。对于新手医生而言，掌握用于此目的的平面内技术具有挑战性。

目的

我们旨在评估与徒手操作相比，针引导装置是否能提高医学生在超声引导平面内技术中在水平和倾斜表面上的进针速度以及针可视化质量。

方法

我们设置了以下三种超声引导技术：在体模水平面、向右倾斜45度平面和向左倾斜45度平面的条件下，使针沿着视轴方向。20名右利手医学生被要求在这三种条件下分别使用和不使用针引导装置（SIVA guide™，富士医疗株式会社，东京，日本）进行超声引导穿刺。

结果

在所有穿刺设置下，使用针引导装置进行超声引导穿刺时到达目标设定成功点所需的时间比不使用该装置的穿刺时间短（最长可达4.14秒（中位数）；<0.01）。使用针引导装置穿刺时的针图像质量评分和参与者对操作难度的自我评估评分均优于不使用该装置的情况。

结论

与徒手操作相比，针引导装置似乎能提高新手医学生在超声引导平面内技术中在水平和倾斜表面上的进针速度以及针可视化质量。
