An Analysis Of Influence Factors Of Newborn Hearingscreening In NICU

Objective To understand the situation of neonatal hearing screening in our hospital, through analyzing the neonatal hearing screening result between the high-risk newborns in the neonatal intensive care unit(NICU) and the normal newborns in the general maternity ward of our hospital. To discuss the influence factors of the hearing screening in NICU, through analyzing the neonatal hearing screening result and relating influence factor of the high-risk newborns in the NICU. Materials and Methods Collect the Transient evoked otoacousti emission(TEOAE) hearing screening results of the high-risk newborn in the NICU and the normal newborn in the maternity ward of our hospital, record the data from eight variables: the screening days, gestational weeks, the mode of delivery(natural or cesarean), birth weight,gender, the side of ears, the history of neonatal asphyxia and the history of meconium aspiration, and use the logistic regression analysis to filer the factors influencing the results of NICU neonatal TEOAE hearing screening. Results 1. 593 cases passed the hearing screening in a total of 640 normal newborn cases(92.7%), while 251 cases passed the hearing screening in a total of 293 NICU high-risk newborn cases(85.7%) that had completed the hearing screening(329 highrisk newborns in total, the completing rate of hearing screening 89.1%). There were obvious differences of passing rate between normal newborns and NICU high-risk newborns(p﹤0.05). The passing rate of hearing screening in NICU high-risk newborns was significantly lower than the rate in normal newborns. 2. The gender, birth weight and the history of neonatal asphyxia all had influence on the passing rate of the TEOAE NICU high-risk newborns hearing screening. The Male newborns’ passing rate was lower than the Female newborns(OR=2.544, p=0.013). The low weight newborns were more difficult to pass the screening than the Non-low weight newborns(OR=2.827, p=0.007). The infants who had the history of neonatal asphyxia were more difficult to pass the screening than the infants who hadn’t the history(OR=2.922, p= 0.016). The sc- reening days, gestational weeks, the mode of delivery, the side of ears and the history of meconium aspiration did not show the impact on the NICU neonatal hearing screening result. Conclusion 1.The passing rate of normal newborns in the general maternity ward is higher than the rate of high-risk newborns in the NICU. 2.The major factors influencing the passing rate include gender, birth weight and the history of neonatal asphyxia. Male newborns, low weight newborns and the newborns who had the history of neonatal asphyxia are more difficult to pass the screening in our hospital. 3.And the NICU newborns with two or more high risk influence factors show a further lower passing rate in the hearing screening. 4.The screening days, gestational weeks, the mode of delivery, the side of ears and the history of meconium aspiration are not significantly related to the passing rate of hearing screening in this research.
