新生儿窒息后脑损伤的CT诊断与临床研究

目的：为提高窒息后脑损伤的诊断率和探讨窒息程度与脑损伤的关系。方法：对３１ 例窒息新生儿头颅ＣＴ的检查并进行轻、重度窒息的ＣＴ对比研究。结果：显示ＣＴ诊断脑损伤的阳性率为５４．８４％ ，窒息程度与脑损伤的关系为： 轻度窒息组ＣＴ示脑损伤的发生率为４４％ ， 重度窒息组为６６％ ， 二者差异无显著性（Ｐ＜ ０．０５）。结论：提示ＣＴ是诊断窒息后脑损伤的可靠检查手段，脑损伤的产生与窒息程度无明显正相关，不能单靠出生时窒息的严重程度而判断脑损伤的发生与预后。

The CT diagnosis of cerebral damages in newborn asphyxia infants and clinical studies

Objective:To improve the diagnosis rate of cerebral damages in newborn asphyxia infants and to explore the relationship between asphyxia degrees and cerebral damages.Method:31 cases of newborn asphyxia infants were examined by cerebral CT.In addition,comparison of CT results by mild and serious asphyxia groups .Result:The CT date indicated that the incidence of cerebral damages were 54.84%,the relationship between asphyxia degree and cerebral damage showed that the incidence of cerebral damage was 44% in mild asphyxia group and 66% in serious group.There were no signficant differences in the two groups(P>0.05). Conclusion:The results showed that CT examination was a reliable manner in diagnosis of cerebral damage that brought from asphyxia at birth.There were no positive correlation between cerebral damages and saphyxia degrees.The production and prognosis of cerebral damages could not be certified simply by the degrees of asphyxia at birth.
