An analysis of multiple influence factors of newborn hearing screening in NICU

Objective To analyze the results of newborn transieutly evoked otoacoustic emission(TEOAE) screening and multiple factors influencing the screening in neonatal intensive care unit(NICU).Methods The results of newborn hearing screening by TEOAE in 244 newborns in NICU from 2002 to 2004 were analyzed retrospectively.Infants who failed in the TEOAE screening accepted ABR test when they were 120 days old.The logistic regression analysis of the multiple factors was used to observe the newborns hearing loss in NICU.Results In NICU,the average pass rate was(85.7%) for the first time and(71.4%) for the second time.Ten newborns failed the TEOAE screening in the hospital.Of them,two infants passed ABR test for both ears.Bilateral and unilateral hearing loss was confirmed in 3 and 5 infants respectively.The prevalence of neonatal hearing disorders in NICU was 32.8‰(8/244).The logistic regression analysis showed that the pass rate of TEOAE reduced evidently with high-risk factors accompanied.Conclusion Pediatrician should pay more attention to the hearing screening,especially to infants suffering from two or more diseases included in high-risk factors in order to find out hearing loss in NICU as early as possible,and early intervention should be given to prevent deafness.
