Auditory health program in neonates of the Intensive anel/or intermediate care units at CAISM/Unicamp


The general goal of this project is to analyze the results obtained by the Auditory Health Program in neonates of the Intensive and/or Intermediate Care Units at CAISM. The specific goals are to operate an universal hearing screening program, assessing more than 95% of the newborns who stayed in the Intensive and/or Intermediate Care Units; to diagnosis hearing loss among the neonates who failed the hearing screening, according to the results of the audiological, otolaryngological and genetic evaluations; to study the morbidity related to hearing impairment in neonates with low birth weight, prematurity, anoxia/hypoxia and congenital infections, compared with others risk indicators in the clinical history of neonates of the intensive care unit; and to analyze the results obtained with amplification, throughout the selection and provision of hearing aids for children with permanent hearing 1055. To make it all possible, we will accomplish the hearing screening program before the hospital discharge in about 1000 newborns of the Intensive Care Unit at CAISM, in one year period, with the Automated Auditory Brainstem Response (ABR). The audiological, otolaryngological and genetic evaluations will be done in approximately 85 infants. The audiological evaluation will occur in the Laboratory of Infant Audiologic Diagnoses at CEPRE/FCM/Unicamp, between one and four months of the child chronological age, in a quiet environment. The procedures will be: anamneses, middle ear status, ABR (watching for electrophysiological threshold and hearing path integrity), and Evoked Otoacoustic Emissions. The cases with suspected hearing loss will be referred for otolaryngological evaluation at the Hospital of Clinics in Unicamp/Otolaryngological Discipline, physical examination and/or image exams. The genetic monitoring will be done in a neonates who fail the hearing tests, with DNA extraction of the mouth mucosa, got by the examiner after the audiological tests using the protocol of the Human Genetic Laboratory - CBMEG. The children with hearing loss will be referred to selection/fitting and provision of hearing aids. In this moment we will analyze the minimum hearing levels with visual reinforcement audiometry preferentially with insert phones coupling with a clinical audiometer (Interacoustics 229e) or with the pediatric audiometer PA2, besides the evaluation of the child with hearing aids. Ali the data collected from the child registration form and the results of the hearing screening and others evaluations will be digitalized in a data-management program for statistical analysis.
