In the three-year period studied, the occurrence of PIVH in premature infants was 6.
However, literature has been signalling a decrease in the occurrence of PIVH in children with very low birthweight, from 50.
PIVH is a common complication in premature, especially those with very low birthweight, and it may lead to important consequences, among them, peripheral and central auditory disorders, including auditory processing disorders that interfere with language development, school learning and subsequent social performance.
14] These data indicate that PIVH can be considered a significant risk indicator for central alteration.
In contrast, research that evaluated 28 children with cerebral palsy, found a higher incidence of grades III and IV PIVH (21%) as compared to grade I (14%).
Indeed, previous study found a statistically significant correlation between weight and the occurrence of PIVH, being proportional to lowest average weight, a fact that led the authors to conclude that the PIVH is a frequent event and can be associated to a birthweight inferior ton 1500g.
2% in the SG), monitoring of PIVH patients was impaired, even considering that 15% had presented central hearing loss at birth.
According to the literature, a difficulty for sound localization has been observed both for premature infants without PIVH8-14 and in preterm infants with PIVH .
In fact, another study also found delay sound localization in premature infants treated in neonatal intensive care unit, without specifying the presence of PIVH.
This result was similar to what was found in the present study, in which seven children (26%) with PIVH presented alterations in their VRAs, while only one child (4.
Such ability was compromised in more than half of children with PIVH (52.
24] These results demonstrate the importance of monitoring the preterm and high-risk children, including those with PIVH.
