目的:探讨新生儿湿肺病的临床表现和胸部X线的特点,提高鉴别诊断能力。方法:分析72例新生儿湿肺病的胸部X线表现。结果:肺泡及肺间质积液、肺淤血、肺气肿是新生儿湿肺症的重要X线征象。结论:出生后5 h内胸片和24~48 h复查是诊断新生儿湿肺病的有效方法,可与其他疾病相鉴别。 Objective: To investigate the clinical manifestations of neonatal pulmonary disease and chest X-ray features to improve the ability of differential diagnosis. Methods: The chest X-ray findings of 72 cases of neonatal wet lung disease were analyzed. Results: Alveolar and interstitial effusion, pulmonary congestion, emphysema are important X-ray signs of neonatal wet lung disease. Conclusion: The chest radiograph within 5 h after birth and 24 to 48 h review are effective methods to diagnose neonatal pulmonary disease, which can be differentiated from other diseases.
