目的：探讨早产儿支气管肺发育不良症的早期诊断和治疗方法。方法：采用回顾性分析方式，从2014年5月至2015年5月在我院分娩的早产儿当中选出7例，其均患有支气管肺发育不良症。对患儿的早期影像学诊断、治疗方法和治疗效果进行研究和记录。结果：本次研究的7例患儿在出生后（21.86±3.61）d后出现支气管肺发育不良症状，根据胸腔X线检查可以看出，患儿肺部呈现不同程度的透明度下降的情况，肺部组织模糊，并伴有网状阴影，其主要集中在肺部中内带周围。采用地塞米松进行早期治疗，其中5例患儿首个疗程疗效显著，而另外2例患儿则需增加一个疗程，患儿治疗有效率为100%。结论：早产儿需要在早期对支气管肺发育不良症进行诊断，一般在出生后3周内开展，一旦发现病症即采用地塞米松早期治疗的效果较好，能够提升患儿的健康度。
Objective: To investigate the early diagnosis and treatment of bronchopulmonary dysplasia in premature infants. Methods: By retrospective analysis, seven of the preterm infants delivered in our hospital from May 2014 to May 2015 were selected, all of whom had bronchopulmonary dysplasia. The early diagnosis of children with imaging diagnosis, treatment and treatment effects were studied and recorded. Results: Seven cases of bronchopulmonary dysplasia were found after birth in this study (21.86 ± 3.61) d. According to the chest X-ray examination, the degree of transparency decreased in the lungs of the children. The tissues are vague and accompanied by reticular shadows, which are mainly concentrated around the inside of the lungs. Dexamethasone for early treatment, of which 5 cases of children with a significant effect of the first course of treatment, while the other two children need to add a course of treatment of children with effective rate of 100%. Conclusion: Preterm infants need to be diagnosed early in the diagnosis of bronchopulmonary dysplasia, usually within 3 weeks after birth, once the illness is found to be better with dexamethasone early treatment, can improve children’s health.
