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

Abstract

ObjectivesTo 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 methodsSix 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.ResultsAdequate 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%.ConclusionThe 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.

Ultrasonographic evaluation of deep vein thrombosis related to the central catheter in hemodialytic patients

“…We demonstrated in a previous publication that medical students can be trained to recognize the major cervical vessels using PoCUS, after a short focused training [ 18 ]. In the current study, the compression technique performed by medical students demonstrated an inferior diagnostic accuracy when compared to that performed by expert physicians.…”

Ultrasonography in undergraduate medical education: a comprehensive review and the education program implemented at Jichi Medical University

“…The use of ultrasound guidance for central venous catheter (CVC) insertion increases procedure success rates and decreases mechanical complications, so this procedure is strongly and broadly recommended [79,80]. In education on ultrasound-guided CVC insertion, understanding the anatomy and physiology of the vessels along with their surrounding structures using ultrasound is the first step, and it is crucial to differentiate arteries and veins to ensure accurate and safe procedures [40,[81][82][83]. There are a number of commercial ultrasound training models available for CVC insertion; however, they may not be cost effective or logistically feasible for distribution to a large number of medical students [84].…”

Avaliação ultrassonográfica de variações anatômicas entre vasos femorais realizada por estudantes de medicina

“…8 Diversos estudos utilizando a US-POC para avaliação de vasos mostraram taxas significativas de variação anatômica existente entre outros vasos centrais: veia jugular interna e artéria carótida. Pazeli et al 9 mostraram que as veias jugulares direita e esquerda foram encontradas em posição anatômica esperada em apenas 48% e 32% dos pacientes estudados, respectivamente.…”

“…A US-POC tem sido difundida na graduação médica como ferramenta de aprendizado e de extensão do exame físico e postula-se que algumas de suas aplicabilidades são de fácil aprendizado por estudantes de medicina submetidos a curto período de treinamento. 9 O presente trabalho tem como objetivo avaliar a prevalência de variações anatômicas de vasos femorais através de US-POC realizada por estudantes de medicina submetidos a curto período de treinamento. A amostra foi calculada e estabelecida em 200 pares de vasos femorais (sendo a artéria e a veia femoral ipsilaterais consideradas um par de vasos), o que representa uma amostra de 100 indivíduos.…”
