新生儿胎粪吸入综合征的超声诊断

Lung ultrasonography for the diagnosis and monitoring of neonatal meconium aspiration syndrome

胎粪吸入综合征(meconium aspiration syndrome,MAS)是新生儿常见危重疾病及导致死亡的主要危险因素之一.以往MAS主要依据胸部X线诊断,但近年来随着超声技术的发展,超声不仅可用于诊断MAS,还能通过多角度扫查反映肺脏不同部位的病变程度.肺脏超声诊断MAS具有准确、可靠、便宜、简便、零辐射、可在床边开展等优点,已在临床广泛应用.本文总结了MAS的超声声像特点,并介绍了肺脏超声在MAS临床诊疗中的其他应用.

Neonatal meconium aspiration syndrome(MAS)is a common critical disease and one of the main risk factors leading to death in newborns.MAS was diagnosed mainly by chest X-ray in the past, but can now easily be diagnosed with lung ultrasound.It can reflect the degree of pathological changes in different parts of the lung through multi-angle scanning, and has many advantages over X-ray including accuracy, reliability, low-cost and simplicity, as well as the fact that ultrasound incurs no risk of radiation damage.It is therefore feasible and convenient to perform at the bedside in a neonatal ward.This paper summarized the sonographic characteristics of MAS, and introduced other applications of lung ultrasonography in the clinical treatment of MAS.
