摘　　要：目的:探讨支气管充气征在新生儿肺透明膜病诊断中的临床价值。方法:回顾分析250例新生儿肺透明膜病的床旁及DR影像表现。结果:肺内支气管充气征197例(占78.8%),肺野透亮度降低240例,肺野内细颗粒状或网格状影133例,肺野磨破璃密度影89例,肺野致密呈"白肺"60例(占24.0%),其中DR片中91.4%(32/35)的"白肺"有支气管充气征,高于床旁片的28.0%(7/25),两者差异有统计学意义(χ2=25.79,P<0.01)。结论:支气管充气征是诊断新生儿肺透明膜病最可靠的征象。"白肺"内支气管充气征是重度新生儿肺透明膜病的特征。Objective:To discuss the clinical value of air bronchogram in the diagnosis of neonatal respiratory distress syndrome.Methods:The X-ray features of 250 cases with neonatal respiratory distress syndrome were retrospectively reviewed.Results:In this cohort,air bronchogram appeared in 197 cases,decreased lung field transmittance in 240 cases,fine granular spot high density shadow in 133 cases,frosted glass like change of the lung fields in 89 cases,'white lung' in 60 cases.In 60 cases 'white lung',air bronchogram,DR for 91.4%(32/35),bedside for 28.0%(7/25);the air bronchogram display rate of DR was higher than bedside.The difference was statistically significant(χ2=25.79,P<0.01).Conclusion:The typical imaging finding in neonatal respiratory distress syndrome is air bronchogram.Air bronchogram in white lung is the feature of severe neonatal respiratory distress syndrome.
