本文应用彩色多普勒动态检测３０例正常新生儿及２５例窒息新生儿脑动脉血流变化并同时时两组新生儿于日龄３、７、１４、２８天进行了神经行为测定（ＮＢＮＡ），以探讨窒息后脑血流变化与新生儿行为的相互关系。研究结果显示正常组新生儿行为及脑血流均显示正常。窒息组日龄３天脑血流异常及新生儿行为异常１７例（６８％），日龄７天双项异常７例（２８％），单项异常４例，日龄１４天双项异常４例（１６％），单项异常２例，一岁后随访，有２例合并脑积水。智力测试（ＣＤＣＣ）１０例，低于正常３例。监测窒息后脑血流参数变化结合ＮＢＮＡ的动态监测，评价窒息后脑损伤的程度及预后，多项指标较单项指标准确、客观、全面。
In this paper, 30 cases of normal newborns and 25 cases of asphyxia newborn cerebral blood flow changes were detected dynamically by color Doppler. At the same time, two groups of newborns were subjected to neurobehavioral determination (NBNA) on days 3, 7, 14 and 28 days. To explore the relationship between cerebral blood flow changes and neonatal behavior after asphyxia. The results show that the normal group of neonatal behavior and cerebral blood flow were normal. In asphyxia group, there were 17 cases (68%) of cerebral blood flow abnormalities and neonatal behavioral abnormalities on day 3 of age, 7 cases (28%) of bi-phase abnormalities on day 7, 4 cases of single abnormalities, 4 cases of abnormalities (16%), single abnormalities in 2 cases, followed up after the age of one, 2 cases of hydrocephalus. Intelligence test (CDCC) in 10 cases, lower than normal in 3 cases. Monitoring changes of cerebral blood flow parameters after asphyxia Combined with the dynamic monitoring of NBNA to evaluate the degree and prognosis of brain injury after asphyxiation, the multiple indicators are more accurate and objective than the single indicators.
