目的：研究高原藏族新生儿缺氧缺血性脑病（Ｈｙｐｏｘｉｃｉｓｃｈｅｍｉｃｅｎｃｅｐｈａｌｏｐａｔｈｙ，ＨＩＥ）及颅内出血的关系和低氧环境对二者的影响。方法：对２６例藏族新生儿缺氧缺血性脑病和颅内出血的ＣＴ表现进行了回顾性分析。结果：ＨＩＥ轻度４例，ＳＤＨ４例，ＳＡＨ３例，ＩＣＨ１例；中度８例，ＳＤＨ６例，ＳＡＨ７例；重度ＨＩＥ１４例，ＳＤＨ１３例，ＳＡＨ１０例，ＩＣＨ２例。结论：（１）ＨＩＥ由轻度到重度的发生率越高，ＳＤＨ及ＳＡＨ发生率也相应增高；（２）ＳＤＨ发生率高于ＳＡＨ的发生率；（３）高原低氧环境可加重ＨＩＥ和颅内出血。
Objective: To study the relationship between Hypoxic ischemic encephalopathy (HIE) and intracranial hemorrhage and the effects of hypoxic environment on them in Tibet Plateau. Methods: A retrospective analysis was performed on the CT findings of 26 Tibetan neonate with hypoxic-ischemic encephalopathy and intracranial hemorrhage. Results: There were 4 cases of mild HIE, 4 cases of SDH, 3 cases of SAH and 1 case of ICH; 8 cases of moderate, 6 cases of SDH and 7 cases of SAH; 14 cases of severe HIE, 13 cases of SDH, 10 cases of SAH and 2 cases of ICH. (2) The incidence of SDH is higher than that of SAH; (3) The plateau hypoxia environment can aggravate the HIE and the incidence of SAH; (2) The incidence of SDH is higher than that of SAH; (3) Intracranial hemorrhage.
