【摘要】 目的 探讨超声结合视频脑电图(VEEG)在早产儿脑损伤早期诊断及预后评价中的应用价值。 方法 选取出生后由产科转入新生儿重症监护室(NICU)的53例早产儿为研究对象,收集其临床资料,根据早产儿临床表现,将出生时Apgar评分低于7分、10d后经MRI检查确认有脑损伤改变的早产儿作为脑损伤组(n=24),其他设为无脑损伤组(n=29),所有早产儿出生后48h~72h均进行颅脑超声检查,且在床旁进行VEEG监测。 结果 超声诊断无脑损伤30例,脑损伤23例。VEEG监测显示脑损伤组及无脑损伤组分别有19例、5例早产儿出现脑电异常情况,脑损伤组VEEG脑电图异常率显著高于无脑损伤组(P<0.05)。超声对早产儿脑损伤早期诊断的灵敏度、特异度、准确度分别为8.33%、89.66%、86.79%;VEEG对早产儿脑损伤早期诊断的灵敏度、特异度、准确度依次为79.17%、82.76%、81.13%;超声结合VEEG对早产儿脑损伤早期诊断的灵敏度、特异度、准确度分别为95.83%、96.55%、96.23%,均高于单纯超声和单纯VEEG检测(P<0.05)。随访结果显示,12月龄时,超声结合VEEG诊断为脑损伤的早产儿MDI、PDI评分均较超声结合VEEG诊断为无脑损伤的早产儿低(P<0.05),脑瘫、癫痫发生率均较其高(P<0.05)。 结论 超声结合VEEG能提高早产儿脑损伤早期诊断效能,在其预后评价中具有重要价值,可供临床借鉴。

Abstract:
【Abstract】 Objective To explore application value of ultrasound combined with video electroencephalogram (VEEG) in early diagnosis of brain development, brain injury and prognosis evaluation in premature infants. Methods 53 premature infants transferred from obstetrics department to neonatal intensive care unit (NICU) after birth were enrolled. Their clinical data were collected. According to their clinical manifestations, premature infants with Apgar score at birth lower than 7 points and brain injury changes confirmed by MRI examination 10d later were enrolled as brain injury group (n=24), while the others were enrolled as brain noninjury group (n=29). Within 48h72h after birth, all premature infants underwent craniocerebral ultrasound examination. VEEG monitoring was performed at the bedside. Results Ultrasound diagnosis showed that there were 30 cases without brain injury and 23 cases with brain injury. VEEG monitoring showed that there were 19 cases and 5 cases with EEG abnormalities in brain injury group and brain noninjury group, respectively. The abnormal rate of VEEG in brain injury group was significantly higher than that in brain noninjury group (P<0.05). The sensitivity, specificity and accuracy of ultrasound and VEEG for early diagnosis of brain development and brain injury in premature infants were (83.33%, 89.66%, 86.79%) and (79.17%, 82.76%, 81.13%), respectively. The sensitivity, specificity and accuracy of their combination were 95.83%, 96.55% and 96.23%, respectively. The followup results showed that at 12month old, MDI and PDI scores in premature infants diagnosed with brain injury by ultrasound combined with VEEG were lower than those without brain injury (P<0.05), while incidence of cerebral palsy and epilepsy was higher than that without brain injury (P<0.05). Conclusion Ultrasound combined with VEEG can improve early diagnosis efficiency for brain development and brain injury in premature infants, which is of important value in prognosis evaluation.
