目的分析不同胎龄早产儿的高危因素,并探讨其与听力损失程度的关系。方法选取早产儿442例列为观察组,同期104例健康新生儿为对照组。对所有纳入对象行听力检查,并对其影响因素进行回归分析。结果研究测试中发现早产儿中听力损伤者有110例,且不同胎龄间的听力损失程度差异具有统计学意义(P<0.05);中度、重度以上听力损失早产儿共24例,胎龄和听力损失程度之间的关系为负相关;早产儿不同出生体重范围间听力损失程度比较差异有统计学意义(P<0.05)。结论新生儿的听力损失情况与低出生体质量、早产、窒息、围生期感染、颅内合并症等因素相关,听力损失的程度与不同胎龄和出生时的体重密切相关,值得临床关注。
Objective To analyze the risk factors of preterm infants of different gestational age and to explore their relationship with the degree of hearing loss. Methods 442 preterm infants were selected as observation group and 104 healthy infants as control group. Hearing tests were performed on all the subjects included, and the regression analysis was conducted on the influential factors. Results There were 110 cases of hearing impairment in preterm infants and there was significant difference in hearing loss among different gestational ages (P <0.05). There were 24 cases of preterm infants with moderate or severe hearing loss, gestational age And the degree of hearing loss was negatively correlated. There was significant difference in hearing loss among different birth weight range in preterm infants (P <0.05). Conclusions The neonatal hearing loss is related to factors such as low birth weight, premature birth, asphyxia, perinatal infection and intracranial complications. The degree of hearing loss is closely related to the weight at different gestational ages and births, which deserves clinical attention.
