Hearing Impairment in Infants with Asphyxia

In recent decades, despite significant advances in medicine and perinatal care, asphyxia remains a serious condition, leading to significant mortality and morbidity. The incidence of severe perinatal asphyxia varies from 1 to 3 per 1000 live births, in developed countries 5-10 per 1000 or more in developing countries, and is the third most common cause of neonatal death (23%) after preterm birth (28%) and severe infection (26%). Neonatal asphyxia is often accompanied by multiple organ failure, mainly involving the kidneys, brain, and heart. Asphyxia results in significant tissue hypoperfusion and reduced oxygen supply, which can cause neurological damage and damage to cochlear hair cells. Under our supervision were 35 (n=30) newborns who were in the neonatal intensive care unit of the Perinatal Center of the Khorezm region in the period from 2018 to 2019. Of these, 22 (I (main) group n=22), who were in the neonatal pathology department, had signs of perinatal CNS damage; The comparison group included 13 newborns (n=13), with Apgar scores >7 in the first minute. There is a clear correlation between the degree of hearing impairment in infants and the degree of pathology of the CNS. However, the degree of impairment of the auditory analyzer increased in parallel with the degree of asphyxia and severity (P≤0,05).
