目的复习新生儿呼吸窘迫综合征(RDS)及早产婴肺的X线影像学表现,并探讨叶间裂显影征在二者鉴别诊断中的价值。方法回顾性分析我院新生儿科收治的有完整资料、经临床证实的100例RDS及100例早产婴肺的影像学改变。结果所有患儿均于出生后2~4 h拍首次床旁胸片,二者的共同影像学表现为两肺野透过度不同程度减低,并见分布不一细小颗粒影;不同影像学表现为100例早产婴肺中有41例出现了叶间裂显影征,而100例RDS中无1例出现叶间裂显影征,3例出现了模糊的、不确切的“支气管充气”征。结论叶间裂显影征是鉴别早期RDS(Ⅰ级)及早产婴肺的重要征象,具有重要的意义,当早产婴肺未出现叶间裂显影征时,二者的鉴别就有一定的困难,这时就需要密切结合临床或RDS后期出现的“支气管充气”征相鉴别。
OBJECTIVE: To review the X-ray findings of neonatal respiratory distress syndrome (RDS) and premature infant lungs and to explore the value of interstitial fissure manifestations in the differential diagnosis between the two. Methods We retrospectively analyzed the imaging data of 100 cases of RDS and 100 cases of premature infants who were admitted to our hospital for neonatology. Results All children underwent the first bedside chest radiograph at 2 ~ 4 h after birth. The common imaging findings of the two groups were reduced to different degrees in the two lung fields with different distribution of small and small granules. The different imaging findings were Among the 100 preterm infants, 41 showed interstitial fission in one of the 100 preterm infant infants, while none of the 100 RDS developed a rupture of the interlobular fissure and 3 had a vague, imprecise “bronchial inflatable” sign. Conclusions The manifestations of interfascicular dehiscence are the important signs to differentiate the early stage RDS (grade Ⅰ) and premature infant lung. It is of great significance. When there is no manifestation of interlobular fissure, At this moment, it is necessary to identify the “Bronchial Inflation” sign in combination with clinical or RDS.
