Lung ultrasound has been increasingly used in the last years for the assessment of patients with respiratory diseases; it is considered a simple technique, now spreading from physicians to other healthcare professionals as nurses and physiotherapists, as well as to medical students. These providers may require a different training to acquire lung ultrasound skills, since they are expected to have no previous experience with ultrasound. The aim of the study was to assess the impact of a short theoretical training focused on lung ultrasound pattern recognition in a population of novice nurse learners with no previous experience with ultrasound.
We included the nurses attending a critical care advanced course for nurses performed at the University of Pavia. Images' interpretation skills were tested on two slide sets (a 25-clip set focused on B-pattern recognition and a 25-clip set focused on identification of pleural movement as lung sliding, lung pulse, lung point, no movement) before and after three 30-minute teaching modules dedicated to general ultrasound principles, B-lines assessment and lung sliding assessment. A cut off of 80% was considered acceptable for correctly interpreted images after this basic course.
22 nurses were enrolled (age 26.0 [24.0-28.0] years; men 4 (18%)); one nurse had previous experience with other ultrasound techniques, none of them had previous experience with lung ultrasound. After the training, the number of correctly interpreted clips improved from 3.5 [0.0-13.0] to 22.0 [19.0-23.0] (p < 0.0001) for B-pattern and from 0.5 [0.0-2.0] to 8.5 [6.0-12.0] (p < 0.0001) for lung sliding assessment. The number of correct answers for B-pattern recognition was significantly higher than for lung sliding assessment, both before (3.5 [0.0-13.0] vs. 0.5 [0.0-2.0]; p = 0.0036) and after (22.0 [19.0-23.0] vs. 8.5 [6.0-12.0]; p < 0.0001) the training. After the training, nurses were able to correctly recognize the presence or the absence of a B-pattern in 84.2 ± 10.3% of cases; lung sliding was correctly assessed in 37.1 ± 15.3% of cases.
Lung ultrasound is considered a simple technique; while a short, focused training significantly improves B-pattern recognition, lung sliding assessment may require a longer training for novice learners.

近年来，肺部超声在评估呼吸系统疾病患者方面得到了越来越多的应用；它被认为是一种简单的技术，现在已经从医生扩展到护士和物理治疗师等其他医疗保健专业人员，以及医学生。这些提供者可能需要不同的培训来获得肺部超声技能，因为他们预计以前没有使用过超声。本研究的目的是评估在没有超声经验的新手护士学习者群体中，进行专注于肺部超声模式识别的短期理论培训的效果。
我们纳入了在帕维亚大学参加护士高级重症监护课程的护士。在进行了三个 30 分钟的教学模块（分别是关于一般超声原理、B 线评估和肺滑动评估的 25 个剪辑的幻灯片集）之后，对两组幻灯片（25 个剪辑的幻灯片集，一组聚焦于 B 模式识别，另一组聚焦于识别胸膜运动，如肺滑动、肺脉冲、肺点、无运动）进行解读技能测试。在这个基础课程之后，将 80%的正确解释图像作为可接受的标准。
共纳入 22 名护士（年龄 26.0[24.0-28.0]岁；男性 4 名[18%]）；一名护士有其他超声技术的经验，没有人有肺部超声经验。培训后，B 模式的正确解读剪辑数从 3.5[0.0-13.0]增加到 22.0[19.0-23.0]（p<0.0001），肺滑动评估的正确解读剪辑数从 0.5[0.0-2.0]增加到 8.5[6.0-12.0]（p<0.0001）。B 模式识别的正确答案数量明显高于肺滑动评估，无论是在培训之前（3.5[0.0-13.0]与 0.5[0.0-2.0]；p=0.0036）还是培训之后（22.0[19.0-23.0]与 8.5[6.0-12.0]；p<0.0001）。培训后，护士能够正确识别 B 模式的存在或不存在，正确率为 84.2±10.3%；肺滑动的正确评估率为 37.1±15.3%。
肺部超声被认为是一种简单的技术；虽然短期的、有针对性的培训显著提高了 B 模式识别能力，但对于新手学习者来说，肺滑动评估可能需要更长的培训。
