【摘要】 本文应用日本产MinoDopplerES-100X仪多普勒频率为2KHz，电源6V，探头为8．2MHz，对14例新生儿缺氧缺血性脑病（HIE）及肺炎恢复期患者8例（对照组）检测了左颈动脉血流动速度。结果表明，14例HIE颈动脉平均血流速度为11．2cm／sec，对照组8例新生儿为13．0cm／sec，t=2．40，P＜0．05。轻度HIE患者颈动脉血流速度为15．6cm／sec，中、重度为10．4cm／sec，P＜0．05。笔者认为HIE为全年性疾病，脑血流速度均有改变，检测颈动脉血流速度，即可估计脑动脉血流速度。更多还原

【Abstract】 We have detected the blood velocity of left carotid artery in 14 cases of neonate HIE and in 8 cases of convalescent neonate pneumonia as control group. The detecting instrument is the Japanese Mino Doppler ES-100X, its frenquency is 2KHz,Power source is 6V, sensor is 8. 2 MHz. The results show that the average of carotid velocity is 11. 2cm/sec in 14 cases of HIE and 13.0cm/sec in 8 cases of control group (t= 2.40, P<0. 05).The carotid velocity is 15. 6 cm/sec in mild HIE,10. 4 cm/sec in severe HIE respectively (P<0.05). We consider that HIE is a systemic disease and blood velocity of whole body is also changed.We can estimate blood velocity of cerebral artery by detecting blood velocity of carotid artery.更多还原
