Abstract

Background: The measurement of the optic nerve sheath diameter (ONSD) via ultrasound is a non-invasive technique to estimate intracranial pressure. Brief training has been shown to be effective in accurately teaching the ONSD technique in specialized healthcare providers. This study evaluates the ability of medical and nursing students, Intensive Care Unit (ICU) nurses, and ICU residents to perform ONSD measurements after a brief training.

Methods: Forty participants underwent a 4-h training session consisting of 30 min of lecture focusing on the key principles of the technique for ONSD measurement, followed by at least 20 measurements with an expert tutor. Thereafter, all participants assessed 5 ONSD measurements on healthy volunteers and their assessments were compared to those by the expert tutor.

Results: All participants successfully visualized the optic nerve and recorded similar values among groups (p > 0.05 for all comparisons). ICU nurse residents and medical students demonstrated a good accuracyof measurements, as defined by an upper and lower limits of agreement with the expert tutor not exceeding 0.5 mm in the Bland-Altman analysis. On the opposite, nurse students had the highest error rates and poor accuracy in ONSD assessment.

Conclusions: These findings highlight the feasibility of training medical students, ICU nurses and residents in ONSD measurement, opening the possibility of a wider application of this technique. After dedicated training, ONSD assessment and monitoring could be performed not only by specialists but also by other healthcare providers, including specialized nurses. This may serve as an additional tool for the rapid triage of patients, even in out-of-hospital settings.

一门理论-实践课程对视神经直径超声测量在不同医护人员中的应用效果。
背景:超声测量视神经鞘直径(ONSD)是一种评估颅内压的无创技术。简短的培训已被证明在专业医疗保健提供者中准确地教授ONSD技术是有效的。本研究评估了医护学生、重症监护病房(ICU)护士和ICU住院医师经过简短培训后进行ONSD测量的能力。方法:40名参与者接受了4小时的培训,其中包括30分钟的讲座,重点介绍ONSD测量技术的关键原理,然后由专家导师进行至少20次测量。之后,所有参与者对健康志愿者进行了5项ONSD测量,并将其评估结果与专家导师的评估结果进行了比较。结果:所有参与者都成功地看到了视神经,各组之间记录的值相似(所有比较p > 0.05)。在Bland-Altman分析中,ICU住院护士和医学生表现出良好的测量准确性,与专家导师一致的上限和下限不超过0.5 mm。相反,护生在ONSD评估中错误率最高,准确性较差。结论:本研究结果突出了对医学生、ICU护士和住院医师进行ONSD测量培训的可行性,为该技术的广泛应用开辟了可能性。经过专门培训,ONSD评估和监测不仅可以由专家进行,还可以由其他医疗保健提供者(包括专业护士)进行。这可以作为对病人进行快速分类的额外工具,即使在院外环境中也是如此。
