Head CT Analysis of high-risk newborn infants

目的 提高对高危新生儿头颅CT异常表现的认识。方法 5 0例高危新生儿 ,出生后 1小时～ 3 0天内行CT检查 ,扫描前半小时肌注鲁米那钠或 10 %水合氯醛口服或灌肠 ,使其安睡。结果 单纯蛛网膜下腔出血 13例 ,脑实质出血 2例 ,脑室内出血 1例 ,硬膜下出血 5例 ,单纯脑缺氧缺血性损害 2 4例 ,新生儿败血症 1例 ,正常CT表现 4例。结论 高危新生儿大部分存在颅内出血或脑缺氧缺血性损害 。

Objective To increase the recognition of head CT abnormal findings among high-risk newborn infants.Methods There are 50 cases of high-risk newborn infants ,everyone of which is given a head CT-scan 1 hours to 30 days after born. Giving luminal intra- muscularly and 10 % chloral hydrate orally or enema half an hour before scan make patients go to sleep .Results 13 cases are identified as simple subarachnoid hemorrhage (SAH) ,2 cases as intracerebral hemorrhage (ICH) ,1 cases as intraventricular hemorrhage (IVH) , 5 cases as subdural hemorrhage (SDH) ,24 cases as hypoxic ischemic damage (HID) ,and 4 cases have normal CT findings.Conclusions Most of high risk newborn infants have intracranial hemorrhage or hypoxic/ischemic damage. So it is sugested that CT examination should be of great benefit in the diagnosis.
