Universelles Neugeborenen-Hörscreening

Summary Early diagnosis of congenital hearing impairment is of great importance to later development and social life of the affected newborns. Otoacoustic emission screening test (OAEs) is a useful tool for early evaluation of hearing in neonates and infants. Some specific risk factors (RFs) associated with prenatal, birth and early postnatal periods may influence the first screening results and further diagnostic findings. Results from OAEs in newborns in University Hospital in Pleven between 2013-2015 years are analyzed. In low birth weight children (under 2500 grams or g), and those born before the 36th gestation week (GW), we found deviations in the OAEs. A negative test result proved higher in newborns subjected to oxygen therapy during the first hours after birth (15.5%), as well as in newborns with higher leucocytes count (11.0%) or higher serum bilirubin value immediately after birth. The average birth weight of the newborns was lower in the cases with negative test results (2848.7±506.5 g) and unilateral negative test results (2823.3±535.2 g), as compared with the group with positive test results (3191.9±387.9 g). Elevated bilirubin levels were more frequently established and can be expected with higher probability in low birth weight children. They shall be subject to a follow-up in time, and newborns with initial negative test result shall undergo a second test 2 months after birth. Long term monitoring is recommended for newborns with these risk factors.

“…The dichotomous nature in combination with the sensibility limit of 30 dB hearing loss qualifies TEOAE as ideal procedure for the early detection of congenital hearing disorders in the context of newborn hearing screening [ 183 ], [ 184 ], [ 185 ], [ 186 ], [ 187 ], [ 188 ], [ 189 ], [ 190 ], [ 191 ], [ 192 ], [ 193 ], [ 194 ], [ 195 ], [ 196 ], [ 197 ]. The measurement and evaluation procedures that were automated for this purpose use a more sophisticated signal detection procedure based on statistical analysis [ 198 ], [ 199 ].…”

“…This suggests the idea of a simultaneous registration of both signals [ 303 ], a method that has not been extended beyond the laboratory stage. In most screening programs, TEOAE and EAEP are combined in a two-stage protocol [ 162 ], [ 186 ]. The applied aABR (automated auditory brainstem responses) are different from conventional BERA in the sense that measurement and signal detection are automated.…”

“…The applied aABR (automated auditory brainstem responses) are different from conventional BERA in the sense that measurement and signal detection are automated. The algorithm used in this context is very similar to the one applied to TEOAE recordings [ 186 ], [ 192 ], [ 195 ], [ 302 ], [ 304 ], [ 305 ], [ 306 ]. See Table 23 (Tab.…”

“…However, mild hearing disorders that affect the cochlear amplifier are detected with higher sensitivity by the TEOAE. A quiet, possibly sleeping child and a low-noise environment are required for both methods of investigation [ 11 ], [ 13 ]. Ultimately, the AABR test is currently the gold standard for newborn hearing screening.…”
