摘　　要：目的:对有围生期窒息病史的新生儿在72 h内行颅脑超声检查,观察脑组织结构及血流动力学改变,探讨此类患儿常见脑损伤类型及超声影像表现。方法:选取90例出生72 h内行首次颅脑超声检查的患儿,经颞囟检测大脑前动脉和大脑中动脉血流动力学变化,主要参数为收缩期峰值血流速度(Vs)、舒张末期血流速度(Vd)以及阻力指数(RI)。结果:在90例患儿中有70例表现不同程度的脑损伤,阳性率为77.8%。结论:颅脑超声可早期发现脑组织结构改变及血流动力学变化,且超声具有床旁检查的优势。Objective： To have a history of perinatal asphyxia newborns, 72 h expert cranial ultrasound examination, observe the structure and hemodynamic changes in brain tissue, discusses the children early common type of brain injury and ultrasound findings. Methods： Children born in the first ultrasound examination in 72h, the anterior temporal skull detect cerebral artery, middle cerebral artery blood flow dynamics, the main parameters： the peak systolic blood flow velocity（Vs）, end-diastolic velocity（Vd）, resistance index（RI）. Results： Seventy cases in 90 cases of brain injury, to different extent in the positive rate of 77.8%. Conclusion： Cerebral ultrasound can early detect brain tissue structure change and hemodynamic changes, ultrasonic has the advantages of bedside examination.
