新生儿呼吸困难胸片与实验室检查的对比观察

Comparative Observation of X-ray Finding and Laboratory Test in Neonates with Respiratory Distress

目的:分析新生儿呼吸困难胸部X线表现,并结合实验室检查结果,以指导临床诊断。方法:分析我院2004年7月至2006年8月132例临床确诊呼吸困难并摄胸片的新生儿的X线表现并与实验室检查结果对比。结果:湿肺69例(52.27%),均发生在出生后48 h内;吸入性肺炎48例(36.36%);呼吸窘迫综合征(RDS)5例(3.79%);未成熟肺10例(7.58%)。各种疾患白细胞总数(WBC)、中性比例及血气分析各有其特点。湿肺血气表现轻度低氧血症和高碳酸血症,WBC与中性比例在诊断上无明显意义;RDS与未成熟肺中,后者白细胞总数与中性比例增高明显,前者血氧分压与二氧化碳分压较后者高。结论:X线表现结合实验室检查对新生儿呼吸困难常见肺部疾病的诊断和鉴别诊断有重要价值。

Objective：To study the relationship between X-ray findings and the laboratory test results in neonates with respiratory distress.Methods： To comparae the X-ray manifestations of 132 cases suffered from respiratory ditress with their results of laboratory test.Results：Wet-lung disease 69 cases（52.27%）,all of their age were under 48 hours.Neonatal aspiratsion syndrome 48 cases（36.36%）,RDS 5 cases（3.79%）,premature lung 10 cases（7.58%）.All the patients had characters in ratio of total white blood cells（WBC）,its neutrophil and its blood gas analysis.Wet-lung disease manifested light hypoxemia and hypercapnia.The ratio of WBC amount and its neutrophil were not significances in diagnosis of wet-lung disease.In RDS and premature lung,WBC and its neutrophil were higher in latter than that in former,PaCO2 and PaO2 were higher in RDS than that in premature lung.Conclusion： It is important to integrate X-ray findings with the results of laboratory test in diagnosis and differential diagnosis of neonatal respiratory ditress.
