Sequential real-time ultrasound examinations were performed in 174 neonates to determine the time of occurrence of cerebroventricular haemorrhage (CVH). Of the 47 infants in whom CVH was detected, in 36 (77%) CVH was present at the first examination. Of the 34 infants with CVH who were examined first within 6 hours of birth, 24 (71%) already had haemorrhage demonstrable at the initial scan. Extension of a CVH after its initial detection occurred in only 3 infants. Of 124 consecutive infants of birthweights less than 1500 g, 38 (31%) developed CVH, 56% of the outborn and 27% of the inborn babies. Our results indicate that most infants who develop CVH have done so within 6 hours of birth.
对174例新生儿进行了连续实时超声检查，以确定脑室出血（CVH）的发生时间。在检测出CVH的47例婴儿中，36例（77%）在首次检查时就存在CVH。在出生后6小时内首次接受检查的34例CVH婴儿中，24例（71%）在初次扫描时就已显示有出血。初次检测到CVH后仅3例出现了CVH扩展。在124例出生体重小于1500g的连续婴儿中，38例（31%）发生了CVH，其中出生后转院的婴儿中有56%，出生时就在本院的婴儿中有27%。我们的结果表明，大多数发生CVH的婴儿在出生后6小时内就已出现CVH。
