采用头颅超声对100例出生时有窒息的新生儿或胎龄≤32周早产儿进行了检查.并配合CT及脑病理解剖进行了对照研究。其中空管膜下—脑室内出血(SEH—IVH)发病率最高为42.4％。其次为缺氧缺血性脑病(HIE)占16.5％。尸解证实超声诊断的正确率为82.8％。超声与CT诊断的符合率为63.3％。成活婴儿在出院后进行了定期的体格和智力发育的随访。
100 cases of neonatal asphyxia at birth or gestational age less than 32 weeks of preterm infants were examined by using cranial ultrasound and compared with CT and brain anatomy. Among them, the highest incidence of SEH-IVH was 42.4%. Followed by hypoxic-ischemic encephalopathy (HIE) accounted for 16.5%. Autopsy confirmed the correct rate of ultrasound diagnosis was 82.8%. The coincidence rate of ultrasound and CT diagnosis was 63.3%. Surviving infants were followed up on regular physical and intellectual development after discharge.
