摘要
目的 应用双功经颅彩色多普勒动态观察 5 3例窒息新生儿的脑血流状况 ,为临床诊断 ,判断疗效及评估预后提供依据。方法 应用双功经颅彩色多普勒分别对窒息组和对照组新生儿进行检测 ,对照组为出生后 3d内 ,窒息组为出生后治疗前 12h内及治疗后第 2～ 7天内 ,分别观察收缩峰值流速 (Vs)、舒张期末流速 (Vd)、阻力指数(RI)。结果 用药前窒息新生儿脑动脉血流速度明显减慢 ,阻力指数升高 ,与对照组相比有显著差异 (P <0 .0 5 ) ,治疗后和对照组相比无显著差异 (P >0 .0 5 )。结论 应用CDFI检测患儿脑血流动力学改变 ,方法安全、简便、省时、无创伤。
Objective To provide the data for the clinical dignosis,treatment and prognosis,a mobile observation of the cerebral bloodflow of 53 asphyxial newborns was done with double functional trans-cranium color Doppler.Metheds The peak current velocity of systole(Vs),the current velocity of the end diastole(Vd)and the resistant index(RI)were observed in less than 3 days after birth in asphyxia group and in 12 hours before treatment and 2 to 7 daysafter treatment in conditional group of newborns.Results Before treatment the bloodflow speed of the cerebral artery slowd down obviously,and the resistant index rose.There were significant differences between the two groups (P<0.05),and no obvious difference after treatment(P>0.05) Conclution To examine the change of newborns'brain hemodynamics by CDFI is a better way with safe,simple,quick,no trauma and can be done repeatedly.
