Abstract
Hearing is paramount for child development; it provides adequate individual integration into a society where oral communication predominates. Hearing disorders may result in language impairment and slower cognitive, intellectual, cultural and social development. Thus, hearing loss should be detected as early as possible so that language and social functioning may develop as normally as possible.
The incidence of hearing loss in neonates is 2-4 cases in every 1000 live births. Hearing loss, especially in mild and moderate forms, may not be recognized before the second year, but may produce great defects in conversational abilities.
The application of mechanical ventilation to the newborn since mid-1960s has presumably allowed the survival of seriously ill infants who would previously have died, and who have had a variety of illnesses, not necessarily primarily respiratory. It could represent a new source of childhood handicap, it seems important to determine its extent and severity in a neonatal intensive care referral unit as artificial ventilation becomes widely used, and survival rates improve.
This study aimed to determine the effect of ventilation (non-invasive and invasive) On preterm hearing impairment.
