新生儿缺氧缺血性脑病脑实质CT值与Apgar评分的相关性研究

Stud y on the relation between CT value of hypoxie-ischemic encephalopathy and Apgar about the newborn

目的探讨新生儿缺氧缺血性脑病(HIE)脑实质CT值与Apgar评分的相关性,为患儿的治疗及预后提供参考数据。方法随机抽取我院62例经过Apgar评分的HIE患儿,通过回顾性分析64排螺旋CT扫描的图像,选取特定的部位,测量CT值,利用统计软件,发现Apgar评分与CT值之间的联系。结果 1早产儿脑白质损害较足月儿更敏感,足月儿脑灰质损害较早产儿更敏感;2出生10 min早产儿、足月儿Apgar评分分别和灰质与桥脑CT值之差(D)呈正相关(r=0.675);3 CT值较Apgar评分更敏感。结论 CT检查能及时、准确、快捷诊断HIE,并能判断脑损害的严重程度,且敏感性高于临床Apgar评分,可以提供客观的具体参考数据。

Objective To study on the relation between the CT values on the newborn hypoxie-ischemic encephal-opathy （HIE） and Apgar score, which can provide reference value on treatment of the newborn and predict the prognosis. Methods Randomly sampled 62 newborn with HIE had Apgar score in our hospital and to analyze their 64 multi-detector helical CT imaging, and used the statistical software to find out the relation between the CT value and Apgar score. Results ① White matter of premature infant was more sensitive than that of mature infant, while gray matter of mature infant was more sensitive than that of premature infant. The CT value was more sensitive than Apgar score. ② The Apgar of premature infant or mature infant and the difference between gray matter and the CT value of Pons was positive corr-elation （r=0.675）.③CT value was more sensitive than Apgar score. Conclusion CT examination can be more sensitive on diagnosis of HIE exactly and quickly. In addition, the report of CT examination can tell the degree of brain damage by providing specific data.
