Meconium aspiration syndrome (MAS) is a rare and life-threatening neonatal lung injury induced by meconium in the lung and airways. Lung ultrasound (LUS) is a quick, easy and cheap imaging technique that is increasingly being used in critical care settings, also for newborns. In this paper we describe ultrasound findings in MAS. Six patients with MAS of variable severity were examined by LUS during the first hours of life. Chest X-rays were used as reference. The following dynamic LUS signs were seen in all patients: (1) B-pattern (interstitial) coalescent or sparse; (2) consolidations; (3) atelectasis; (4) bronchograms. No pattern was observed for the distribution of signs in lung areas, although the signs varied with time, probably due to the changing localisation of meconium in the lungs. LUS images corresponded well with X-ray findings. In conclusion, we provide the first formal description of LUS findings in neonates with MAS. LUS is a useful and promising tool in the diagnosis and management of MAS, providing real-time bedside imaging, with the additional potential benefit of limiting radiation exposure in sick neonates.
胎粪吸入综合征（MAS）是一种由肺和气道内的胎粪引起的罕见且危及生命的新生儿肺损伤。肺部超声（LUS）是一种快速、简便且廉价的成像技术，在重症监护环境中越来越多地被使用，新生儿也适用。在本文中，我们描述了MAS的超声检查结果。在出生后的最初几个小时内，对6例病情严重程度各异的MAS患者进行了LUS检查。胸部X光片用作对照。所有患者均出现以下动态LUS征象：（1）B线（间质）融合或稀疏；（2）实变；（3）肺不张；（4）支气管充气征。尽管这些征象随时间变化，可能是由于胎粪在肺内位置的改变，但在肺区域内未观察到征象分布的特定模式。LUS图像与X光检查结果吻合良好。总之，我们首次对患有MAS的新生儿的LUS检查结果进行了正式描述。LUS是诊断和管理MAS的一种有用且有前景的工具，可提供床旁实时成像，还有减少患病新生儿辐射暴露的潜在额外益处。
