Lung ultrasound (LUS) plays a critical role in the SARS-CoV-2 pandemic. Evidence is mounting on its utility to diagnose, assess the severity and as a triage tool in the ED. Sonographic features correlate well to computed tomography (CT) chest findings and a bedside LUS performed by a trained clinician along with clinical examination, could be an alternative to chest X-ray and CT chest in these highly infectious patients. In this article, we have described a step-by-step approach to LUS in COVID patients and the CLUE (COVID-19 LUS in the ED) protocol, which involves an anatomical parameter, the severity of lung changes, objectively scored using the validated LUS scoring system and a physiological parameter, oxygen requirement. We believe this CLUE protocol can help risk-stratify patients presenting to ED with suspected COVID-19 and aid clinicians in making appropriate disposition decisions.
肺部超声（LUS）在 SARS-CoV-2 大流行中发挥着关键作用。越来越多的证据表明，它可用于诊断、评估严重程度，并作为急诊科的分诊工具。超声特征与计算机断层扫描（CT）胸部检查结果密切相关，经过培训的临床医生在床边进行 LUS 检查，结合临床检查，可能替代高度传染性患者的胸部 X 线和 CT 胸部检查。在本文中，我们描述了一种针对 COVID 患者的 LUS 逐步方法和 CLUE（急诊科 COVID-19 LUS）方案，该方案涉及一个解剖参数，即使用经过验证的 LUS 评分系统客观评分的肺部变化严重程度，以及一个生理参数，即氧气需求。我们相信，这个 CLUE 方案可以帮助风险分层急诊科中出现 COVID-19 疑似症状的患者，并帮助临床医生做出适当的处置决策。
