Abstract:
OBJECTIVE:To analyze the results of hearing screening and the related factors in 3200 newborn infants, in order to know the incidence of neonatal hearing disorders.
METHOD:Three thousand two hundred cases of newborn infants born during 2014-01 and 2015-03 were tested for hearing screening. According to risk factors, newborns were divided into the normal newborn group (2945 cases) and the high-risk neonatal group (255 cases). Using fast brainstem auditory evoked potential (AABR) to screen the hearing screening of newborn infants with 3~5 d; those who did not pass the screening, after the birth of 30~42 d re-screening; re-screening still not pass, within 3 months line diagnostic auditory brainstem evoked potential (diagnostic ABR) confirmed. Comparative analysis of newborn hearing screening by screening through rate, re-screening through rate and hearing impairment rate proportional relationship with the relevant factors, and the differences of hearing screening results in the normal newborn group and the high-risk neonatal group.
RESULT:(1)The rate of neonatal hearing screening did not pass was 7.50% (240/3,200); 30 cases was not involved in re-screening, the rate of re-screening did not pass was 15.24% (32/210); hearing impairment rate is about 0.38%(12/3200), and the bearing impairment positive rate was 1.31% (42/3200). (2) There was no significant difference of different delivery mode, neonatal sex in newborn hearing screening through rate, re-screening through rate and hearing impairment rate (P > 0.05). Different gestational age, maternal age in newborn hearing screening through rate, re-screening through rate and hearing impairment rate, the difference was statistically significant (P < 0.05). (3) Screening through rate and re-screening through rate of the high-risk neonatal screening group were significantly lower than the normal newborn group (P < 0.05), and hearing impairment rate was higher than normal newborn group (P < 0.05).
CONCLUSION:Strengthen prenatal health care, to reduce abnormal childbirth conditions (preterm birth, neonatal asphyxia), universal newborn hearing screening and improve screening accuracy, and to strengthen newborns with risk factors for early diagnosis and intervention, to reduce the incidence of neonatal hearing impairment has important significance.
