彩超检测新生儿缺氧缺血性脑病脑血流动力学变化

Hemodynamic changes in cerebral blood fiow for the newborn infants with hypoxic-ischemic encephalopathy by colour doppler sonography

目的探讨新生儿缺氧缺血性脑病(hypoxic-ischem ic encephalopathy,HIE)脑血流动力学的变化。方法对32例HIE患儿的大脑前动脉血流参数进行检测,并与20例健康新生儿进行对照。结果出生后48 h内,患儿大脑前动脉收缩期、舒张末期血流速度均下降,其中以舒张末期血流速度下降为明显,与对照组比较,差异有显著性(P<0.05)。脑血管阻力指数升高,与对照组比较,差异有非常显著性(P<0.01)。结论对HIE患儿脑血流动力学的观察,有助于对脑损伤的诊断和治疗。

Objective To study the change of cerebrovascular hemodynamics of hypoxic-ischemic encephalopathy neonate . Method Parameters of the blood flow of arteria cerebri anterior of 32 neonates were examined and compared with that of the control group. Results The systolic enddiastolic of arteria cerebri anterior descended significantly within postnatal 48h （ P 〈 0. 05 ） in comparison with the control group. Conclusion The observation of hemodynamics of asphyctic neonates will be in faviour of the diagnosis and treatment of cerebral injury of hypoxic-ischemic encephalopathy neonates .
