Auditory pathway maturational study in small for gestational age preterm infants

Abstract

The findings suggest that, in the premature infants, the maturational process of the auditory pathway occurs in a similar rate for SGA and AGA. These results also suggest that prematurity is a more relevant factor for the maturation of the auditory pathway than birth weight.

Efeitos da prematuridade na aquisição da linguagem e na maturação auditiva: revisão sistemática

“…As there was no significance in failure rates after 42 hours in both groups, they concluded that the results in late preterm infants are related to late maturation of the auditory system after birth, in agreement with one of the studies selected (34) , in which it was verified that maturation of the auditory system has a greater influence than factors such as weight at birth. Another article (33) also points to the importance of maturation, since it has been found that, although preterm infants can benefit from earlier exposure to the language environment that favors speech transmission, such exposure has no effect on language acquisition in isolation.…”

“…They observed that premature infants presented a lower than average index of language related to expressive communication. Thus, it is important to investigate and understand the development of children with risk factors Two studies (34,35) assessed premature infants small for gestational age with regard to hearing. In one of the studies, the authors (34) monitored maturation of the auditory pathway in premature neonates small for gestational age (SGA) by analyzing absolute and interpeak latencies of the auditory brainstem evoked potential (ABEP) in the first six months of age compared to infants appropriate for gestational age (AGA).…”

It was also observed that preterm nurslings appropriate and small for gestational age present accelerated maturation, particularly during the first three months of age, thus characterizing a catch-up period with regard to hearing.…”

“…In these, assessments of language and hearing were part of the procedures to carry out such studies in a complementary basis (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27) . On the other hand, other studies found focused mainly on language and/or hearing impairments in premature infants (28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38) .…”
