摘要
目的:观察发热性惊厥患儿是否伴有脑血流动力学异常。方法:采用经颅多普勒(TCD)超声技术,测定 36例发热性惊厥患儿(观察组)及 45名健康儿童(对照组)脑底动脉血流速值和频谱形态。结果:观察组的动脉血流速值收缩期最大峰流速(Vs)、舒张末期峰流速(Vd)和平均峰流速(Vm)与对照组比较均有显著性差异(P<0.05)。观察组的大脑中动脉血流速值异常率为100%。结论:发热性惊厥患儿惊厥时脑血流动力学异常。TCD超声技术可用于动态观察惊厥后患儿脑供血情况。
Objective: To observe whether abnormal cerebral blood flow velocity occurs or not in children with hyperpyretic convulsion. Methods: Blood now velocity and spectral pattern of cerebral artery in forty-five healthy children and thirty-six children with hyperpyretic convulsion were detected by Transcranial Doppler (TCD) ultrasound. Results: Systolic velocity (Vs),the enddiastolic velocity (Vd) and mean velocity (Vm) of cerebral artery were significantly different between the two groups (P<0.05) .Abnormal blood flow of middle cerebral artery occurred in 100% of the observation group. conclusion: Abnormal cerebral blood now velocity occures in children with hyperpyretic convulsion. TcD can be used to observe dynamically the blood supply of the cerebral artery in children after hyperpyretic convulsion.
