摘要

目的:探讨医学生在快速、集中训练后对颈内静脉及其解剖变化的评价能力。我们还旨在评估在传统技术(tt)和超声监测(US)下模拟IJV穿刺的成功率。材料与方法:对6名无US经验的医学生进行4小时的US理论实践训练,并对105例患者的IJV和颈总动脉(CCA)进行评估。他们还模拟了在一个划定的点穿刺IJV,理论上在那里进行了TT。结果:95%的患者获得了足够的图像;右侧IJV更常见于与CCA相关的前外侧位置(38%)。在左侧,最常见的体位是前位(36%)。相对于CCA, IJV的口径差异很大。用US观察到,TTs在IJV穿刺模拟中的成功率为55%。结论:培养医学生识别颈部大血管是一项简单、快速、可行的任务,可纳入本科医学课程。

Point-of-care ultrasound evaluation and puncture simulation of the internal jugular vein by medical students.

Objectives: To show that medical students can evaluate the internal jugular vein (IJV) and its anatomical variations after rapid and focused training. We also aimed to evaluate the success rate of IJV puncture in simulation following traditional techniques (TTs) and monitored via ultrasound (US).

Materials and methods: Six medical students without experience with US were given 4 h of theoretical-practical training in US, and then evaluated the IJV and common carotid artery (CCA) of 105 patients. They also simulated a puncture of the IJV at a demarcated point, where a TT was theoretically performed.

Results: Adequate images were obtained from 95% of the patients; the IJV, on the right side, was more commonly found in the anterolateral position in relation to the CCA (38%). On the left side, the most commonly position observed was the anterior (36%). The caliber of the IJV relative to the CCA greatly varied. The success rate in the IJV puncture simulation, observed with US, by the TTs was 55%.

Conclusion: The training of medical students to recognize large neck vessels is a simple, quick, and feasible task and that can be integrated into the undergraduate medical curriculum.
