ABSTRACT

OBJECTIVE: To explore the influence and significance of preeclampsia with different degrees of gestational hypertension on infant hearing.METHODS: Totally 1046 newborns whose mothers had a history of pre-eclampsia with hypertensive disorder complicating pregnancy were divided into groups according to the severity of pre-eclampsia and whether they were premature or not from Jan. 2015 to Dec. 2017 in the Forth Hospital of Shijiazhuang.Hearing tests were conducted and compared with newborns whose mothers had no history of pre-eclampsia with hypertensive disorder complicating pregnancy.RESULTS: Of the 14 741 infants studied,57 were finally diagnosed with sensorineural hearing loss,with a total abnormality rate of 0.39%(57/14 741).Among them,34 infants with pre-eclampsia without hypertensive disorder complicating pregnancy had an abnormality rate of 0.25%.There were 12 infants with mild preeclampsia in their mothers,with an abnormality rate of 1.47%.There were 11 infants whose mothers had severe preeclampsia,with an abnormality rate of 4.76%.There were significant differences between mild group and control group,severe group and control group,and severe group and mild group(P0.05),but there was significant difference between the severe group and the control group,and between the severe group and the mild group(P<0.01 and P<0.05,respectively).CONCLUSION: Premature infants with severe hypertensive disorder complicating pregnancy and preeclampsia are at high risk of hearing impairment.The higher the degree of hypertension,the higher the rate of hearing impairment.The emphasis should be put on strengthening the hearing monitoring and follow-up of such children.
