摘　　要：目的:探讨早产儿听力损伤的相关因素。方法:对203例不同出生胎龄早产儿进行自动听性脑干反应(automatic auditory brainstem response,AABR)听力检测,分析各种高危因素下AABR的通过率以及听力损伤的程度。结果:203例早产儿存在听性脑干反应结果异常43例(占21.2%),其中中重度以上异常者占44%。胎龄、黄疸程度、低氧程度与听性脑干反应结果异常程度之间存在相关关系(P<0.05)。结论:胎龄、低氧及黄疸是影响早产儿听力损伤的重要因素,早产儿胎龄越小,低氧及黄疸程度越重听性脑干反应结果异常的发生率越高,程度越严重。Objective：To explore the correlative factors of hearing loss in preterm infants.Methods： The automatic auditory brainstem response（AABR） results were recorded in 203 premature infants with different gestational age.AABR passing rates and the degree of hearing loss were analyzed in those patients with various high-risk factors.Results： Forty-three（21.2%） preterm infants had hearing loss among the 203 preterm infants,while patients with moderate and severe hearing loss were accounted for 44% of the total.Gestational age,the degree of jaundice and hypoxia had correlation（P 0.05） with the degree of hearing loss.Conclusion： Gestational age,the degree of hypoxia and jaundice are the correlative factors for hearing impairment.
