尽管对极低出生体重儿的处理,近来有所改善,并使新生儿的死亡率下降,脑室内出血(IVH)在新生儿发病及死亡上仍起重要作用。尸解发现死亡早产儿中,IVH约占50～70％,存活的极低出生体重儿中,用计算机轴向X线断层(CAT)扫描,阳性率亦达43～55％,这数字远比过去报导的临床拟诊数为高。
Although treatment of very low birth weight children has improved recently and neonatal mortality has declined, intraventricular hemorrhage (IVH) still plays an important role in neonatal morbidity and mortality. Autopsy found that death of preterm infants, IVH accounted for about 50 to 70% of surviving very low birth weight children with computerized axial tomography (CAT) scan, the positive rate of 43 to 55%, this figure is far more than The number of clinically diagnosed cases reported in the past was high.
