The relationship between neonatal pathologic jaundice and hearing impairment

摘要: 目的:探讨新生儿病理性黄疸与听力损害的关系。方法:将82例足月新生儿病理性黄疸按血清总胆红素水平分为轻中度黄疸组50例,总胆红素221~340mol/L;重度黄疸组32例,总胆红素340mol/L;以同期产科出生的生理性黄疸足月新生儿40名为对照组。均于出生后1周内行脑干听觉诱发电位(BAEP)检测。结果:轻中度黄疸组中BAEP单耳异常10例,双耳异常2例,BAEP异常发生率24.0%;重度黄疸组中BAEP单耳异常8例,双耳异常4例,BAEP异常总发生率37.5%;对照组中BAEP单耳异常2例,发生率5.0%,3组BAEP异常发生率差异有统计学意义(P0.01)。结论:新生儿病理性黄疸较生理性黄疸更易发生听力损害,且血清总胆红素水平越高,持续时间越长,听力损害的发生率越高,程度越重。Abstract: Objective: To explore the relationship between neonatal pathologic jaundice and hearing impairment. Methods: Eighty-two neonates with pathologic jaundice were divided into mild-moderate jaundice group 50 cases( the bilirubin was 221 to 340 mol / L) and heavy jaundice group 32 cases( the bilirubin was higher than or equal to 340 mol / L) according to the level of bilirubin. Fourty neonates with physiologic jaundice were set as control group. Auditory evoked potentials( BAEP) of all neonates were measured within 1 week after birth. Results: The BAEP abnormality in single ear for 10 cases and two ears for 2 cases in mild-moderate jaundice group were found,the abnormal rate of BAEP was 24. 0%. The BAEP abnormality in single ear for 8 cases and two ears for 4 cases in heavy jaundice group were found,the abnormal rate of BAEP was 37. 5%. The BAEP abnormality in single ear for 2 cases in control group were found,the abnormal rate of BAEP was 5. 0%. The differences of BAEP abnormal rate in three groups had statistical significance( P 0. 01). Conclusions: The hearing of neonate with pathologic jaundice is easy to be harmed. The incidence and degree of hearing impairment are higher and heavy with the serum total bilirubin level increasing and the duration lengthening.
