Abstract：Objective In this work ,the newborn babies with the history of asphyxia in the perinatal period were subjec‐ted to the bedside cerebral ultrasound examination within 72 h .The brain structure and hemodynamic changes were ob‐served so as to early explore the the common type of brain injury and sonographic findings in these children .Methods Children born within 72 h underwent the bedeside cerebral ultrasound examination for the first time .The main parame‐ters ,which reflected the blood flow dynamic changes in anterior cerebral artery and middle cerebral artery ,in terms of the peak systolic blood flow velocity (Vs) ,end‐diastolic velocity (Vd) ,and resistance index (RI) ,were detected with doppler technique via temporal fontanelle .Results By the Ultrasound test within 72 h after birth ,47 out of 60 cases were shown brain injury at different extent .The positive rate was 78 .3% .Conclusion Children with asphyxia in the perinatal period are prone to hypoxic ischemic brain damage .Cerebral ultrasound can early detect the changes of brain tissue structure and hemodynamics .Checking within 72 h ,the positive rate is high .For the severe patients in NICU ,ultrasound has the ad‐vantages for bedside examination .
