床旁彩色多普勒超声在诊断新生儿颅脑疾病中的应用

目的研究床旁彩色多普勒超声在诊断新生儿颅脑疾病中的应用价值。方法选取2015年2月-2016年7月我院94例存在高危因素并接受床旁彩色多普勒超声检查的新生儿为研究对象,分析头颅彩超检查结果以及MRI结果。结果两种检查方法对颅内出血II级、颅内出血III级、颅内出血IV级、缺氧缺血性脑病、脑室扩张、脑实质内出血、化脓性脑膜炎临床检出率的对比无统计学意义(P0.05);床旁多普勒超声诊断法对脉络丛囊肿、室管膜下囊肿以及颅内出血I级的临床检出率明显高于MRI(P0.05),而MRI对蛛网膜下腔出血或者硬膜下出血临床检出率显著高于床旁多普勒超声(P0.05),部分患儿诊断结果得到手术/尸检证实。结论相对于MRI,床旁多普勒超声可提高新生儿脉络丛囊肿、颅内出血I级以及室管膜下囊肿的检出率,具有较高的应用价值。

Application of Bedside Ultrasound in the Diagnosis of Neonatal Craniocerebral Diseases

Objective To study the application value of bedside ultrasound in the diagnosis of neonatal craniocerebral diseases.Methods A total of 94 high risk neonates accepted bedside color doppler ultrasound examination in our hospital from February 2015 to July 2016 were taken as the clinical research objects. The color doppler ultrasound and MRI result of the craniocerebral were compared and analyzed.Results There were no significant differences in clinical detection rates of intracranial hemorrhage level II, III and IV, hypoxic ischemic encephalopathy, ventriculomegaly, intracerebral hemorrhage and purulent meningitis between color doppler ultrasound and MRI(P>0.05), the clinical detection rate of beside doppler ultrasound in the diagnosis of choroid plexus cyst, subependymal cysts and intracranial hemorrhage level I was significantly higher than that of MRI(P<0.05), the clinical detection rate of MRI in the diagnosis of subarachnoid hemorrhage and subdural hemorrhage was significantly higher than that of beside doppler ultrasound(P<0.05). Partial diagnosis results were confirmed by operation or autopsy. Conclusion Compared with MRI, bedside doppler ultrasound has high detection accuracy of choroid plexus cyst, intracranial hemorrhage level I and subependymal cysts in neonates, and which deserve generalization.
