[Clinical and electrophysiological studies of the organ of hearing of newborn infants. III. Evaluation of the organ of hearing of newborn infants from high risk pregnancy using brain stem evoked response audiometry (ABR)].
In a group of 130 tested newborns, pathological brain stem responses derived from acoustic stimulus was achieved in 28 cases (21.5%). 85.2% of newborns in this group of birthed babies comprised a high-risk pregnancy group. Based on criteria evaluating monitoring and parameters achieved ABR responses: conduction hearing disorders were found in 7 newborns, sensori-neural in 12 cases, and neurological dysfunction was observed in 9 cases. Control testing was carried through for three months following the initial evaluation allowing for the elimination of 12 children in a group of 19 for further testing and observation. This represents 42.85% of children initially evaluated as possessing a hearing disorder and 9.2% from the total of those tested. Results obtained during successive control testing were carried-out in a 3-6 month period following the initial examination and allowed for decisions to be made. Conforming to: 4 children (3.07%) were supplied with hearing aids and hearing rehabilitation begun, 1 child (0.76%) was referred to rehabilitation the deaf, whereas the 2 remaining children (1.53%) are currently under neurological observation. Nonetheless, testing older children eliminates cases that present with lack of success at the initial evaluation or transitory hearing impairment that is self-limited, although ABR testing, while the child is on the unit, allows for the introduction of hearing-organ controls of newborns based on population testing.
