新生儿窒息后脑损伤的CT诊断与临床分析

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43例窒息新生儿头颅行CT检查,并进行轻、重度窒息组的CT对比。结果:显示CT诊断脑损伤的阳性率为53.49％,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48％,重度窒息组为61％,两者比较差异无显著性(P>0.05)。结论:提示CT是窒息后脑损伤的重要的辅助诊断手段,脑损伤的产生与窒息程度无明显正相关,不能仅靠出生时窒息的严重程度而判断脑损伤的发生和预后。

The CT Diagnosis of Cerebral Damages in Newborn Asphyxia Infantss and Clinical Analysis

Objective To improve the diagnosis rate of cerebral damages in newborn asphyxia infants and to explore the relationship between asphyxia degrees and cerebral damages.Methods:43 cases of newborn asphyxia infants were examined by cerebral CT. In addition,the CT results were compared between mild and serious asphyxia groups. Result:The CT data indicated that the incidence of cerebral damages were 53.33% . The relationship between asphyxia degree and cerebral damage showed that the incidence of cerebral damage was 48% in mild asphxia group, and 61 % 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 method in diagnosis of cerebral damage caused by asphyxia at birth. There are no positive correlation between cerebral damages and asphyxia degrees.The cause and prognosis of cerebral damages can not be judged simply by the degrees of asphyxia at birth.
