这篇综述的目的是将肺超声（PU）用于诊断的证据系统化，2019年冠状病毒病患者的监测或出院标准（COVID-19）。将在2019年12月1日至2020年7月5日期间通过逆转录聚合酶链反应（RT-PCR）确认患有COVID-19的COVID-19患者使用PU进行诊断和监测或作为出院标准的证据与胸部X线照相（TR）获得的证据进行比较，胸部计算机断层扫描（CT）和RT-PCR。研究的类型,使用PU的动机，人口,传感器类型和协议，评估PU结果以及与TR和/或胸部CT和/或RT-PCR的定量或定性相关性。共涉及28篇文章，包括418名患者。平均年龄为50岁(标准偏差：25.1岁)，有395名成人和23名儿童。一百四十三个是女人，其中有13人怀孕了。最常见的结果是弥漫性，聚结和汇合的B系。复数线是不规则的，中断的或增厚的。胸膜下实变为结节状，叶或多叶。TR与胸部CT之间具有良好的定性相关性，与胸部CT之间的定量相关性为r=0.65（p<0.001）。44例患者仅接受PU评估。PU是诊断和监测的有用工具，也是COVID-19患者出院的标准。
The goal of this
review was to systematize the evidence on pulmonary ultrasound (PU) use in diagnosis, monitorization or hospital discharge criteria for patients with coronavirus disease 2019 (COVID-19). Evidence on the use of PU for diagnosis and monitorization of or as hospital discharge criteria for COVID-19 patients confirmed to have COVID-19 by reverse transcription polymerase chain reaction (RT-PCR) between December 1, 2019 and July 5, 2020 was compared with evidence obtained with thoracic radiography (TR), chest computed tomography (CT) and RT-PCR. The type of study, motives for use of PU, population, type of transducer and protocol, results of PU and quantitative or qualitative correlation with TR and/or chest CT and/or RT-PCR were evaluated. A total of 28 articles comprising 418 patients were involved. The average age was 50 y (standard deviation: 25.1 y), and there were 395 adults and 23 children. One hundred forty-three were women, 13 of whom were pregnant. The most frequent result was diffuse, coalescent and confluent B-lines. The plural line was irregular, interrupted or thickened. The presence of subpleural consolidation was noduliform, lobar or multilobar. There was good qualitative correlation between TR and chest CT and a quantitative correlation with chest CT of r = 0.65 (p < 0.001). Forty-four patients were evaluated only with PU. PU is a useful tool for diagnosis and monitorization and as criteria for hospital discharge for patients with COVID-19.
