目的 为了解高危新生儿脑干及听觉功能障碍情况.方法 于1995年8月～1996年1月对128例高危新生儿进行脑干听觉诱发电位(Anditory Brainstem Responses—ABR)测定.结果 急性期高危新生儿ABR异常率为51.4%,其中高胆红素血症,低体重儿,窒息和丁胺卡那霉素应用组ABR异常率分别为61.1%、66.7%、53.8%和 2.8%.血清胆红素(Sb)值>290.7μmol/L和重度窒息儿ABR异常率明显高于Sb<290.7μmol/L和轻度窒息儿.早产儿和足月小样儿ABR异常率无明显差异.丁卡组对听阀的近期影响不大.结论 高危新生儿是脑干和听觉功能障碍的高危人群,应当密切随防和早期干预.
Objective To understand the brainstem and auditory dysfunction in high-risk neonates.Methods 128 cases of high-risk neonates were tested for the brainstem auditory-evoked potential (ABR) from August 1995 to January 1996. Results The high risk of acute phase The abnormal rate of ABR in neonates was 51.4%, and the ABR abnormalities in hyperbilirubinemia, low birth weight, asphyxia and amikacin groups were 61.1%, 66.7%, 53.8% and 2.8%, respectively. Abnormal rate of ABR in patients with severe acute asphyxia was significantly higher than that with Sb <290.7μmol / L and children with mild asphyxia. There was no significant difference in ABR abnormalities between preterm and full-term children And has little effect on the hearing valve in the near future.Conclusion High-risk neonates are risk groups with brainstem and auditory dysfunction and should follow the prevention and early intervention closely.
