Patients with novel coronavirus disease (COVID-19) typically present with bilateral multilobar ground-glass opacification with a peripheral distribution. The utility of point-of-care ultrasound has been suggested, but detailed descriptions of lung ultrasound findings are not available. We evaluated lung ultrasound findings in 10 patients admitted to the internal medicine ward with COVID-19. All of the patients had characteristic glass rockets with or without the Birolleau variant (white lung). Thick irregular pleural lines and confluent B lines were also present in all of the patients. Five of the 10 patients had small subpleural consolidations. Point-of-care lung ultrasound has multiple advantages, including lack of radiation exposure and repeatability. Also, lung ultrasound has been shown to be more sensitive than a chest radiograph in detecting alveolar-interstitial syndrome. The utilization of lung ultrasound may also reduce exposure of healthcare workers to severe acute respiratory syndrome-coronavirus-2 and may mitigate the shortage of personal protective equipment. Further studies are needed to evaluate the utility of lung ultrasound in the diagnosis and management of COVID-19.
新型冠状病毒病（COVID-19）患者通常表现为双侧多肺叶磨玻璃影，呈外周分布。床边超声检查具有一定的作用，但其肺部超声表现的详细描述尚不清楚。我们评估了 10 例因 COVID-19 入住内科病房的患者的肺部超声表现。所有患者均具有特征性的玻璃火箭征，伴有或不伴有 Birolleau 变异（白肺）。所有患者均存在增厚的不规则胸膜线和融合的 B 线。10 例患者中有 5 例存在小的胸膜下实变。床边肺部超声具有多种优势，包括无辐射暴露和可重复性。此外，肺部超声在检测肺泡-间质综合征方面比胸部 X 线更敏感。肺部超声的应用还可能减少医护人员接触严重急性呼吸综合征冠状病毒 2 的机会，并缓解个人防护设备的短缺。需要进一步研究评估肺部超声在 COVID-19 的诊断和管理中的作用。
