目的探讨经颅超声检查技术在新生儿缺氧缺血性脑病中的临床价值。方法选取我院收治的临床诊断为缺氧缺血性脑病的新生儿180例作为研究对象,对患儿的二维超声与大脑动脉多普勒超声状况进行分析。结果缺氧缺血性脑病新生儿180例的二维超声图像显示的异常表现主要包括:脑水肿38例(21.11%),脑室周围白质软化114例(63.33%),室管膜下出血17例(9.44%),脑室内出血11例(6.11%);在脉冲多普勒上对缺氧缺血性脑病新生儿进行大脑动脉RI检测,发现RI>0.90的患儿有3例(16.67%),RI值为0.71~0.90的患儿有86例(47.78%),RI值为0.55~0.70的有48例(26.67%),RI<0.55的患儿有42例(23.33%)。结论对缺氧缺血性脑病新生儿采用经颅超声检查技术进行诊断,能够有效提升诊断准确率,具有较高的临床应用价值。
Objective To investigate the clinical value of transcranial ultrasound in neonatal hypoxic-ischemic encephalopathy. Methods A total of 180 newborns diagnosed as hypoxic-ischemic encephalopathy admitted to our hospital were enrolled in this study. Two-dimensional ultrasound and cerebral Doppler echocardiography were analyzed. Results The two-dimensional ultrasound images of 180 neonates with hypoxic-ischemic encephalopathy showed abnormalities mainly in 38 cases (21.11%) of cerebral edema, 114 cases (63.33%) of periventricular leukomalacia, 17 cases of subependymal hemorrhage (9.44%) and 11 (6.11%) intracerebral hemorrhage. RI was detected in neonates with hypoxic-ischemic encephalopathy by pulsed Doppler and found that there were 3 cases (16.67%) of children with RI> 0.90, There were 86 cases (47.78%) with RI of 0.71 ~ 0.90, 48 cases (26.67%) with RI of 0.55 ~ 0.70 and 42 cases (23.33%) with RI <0.55. Conclusion The diagnosis of neonatal hypoxic-ischemic encephalopathy using transcranial ultrasound examination can effectively improve the diagnostic accuracy, and has a high clinical value.
