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.
