Developmental outcome of infants with grade III intraventricular hemorrhage
Insights
Premature infants with severe brain bleeds (grade III intraventricular hemorrhage) often experience developmental delays, particularly motor deficits. Early, comprehensive assessments are crucial for understanding the full impact of this condition.
Area of Science:
- Neonatal neurology
- Developmental pediatrics
- Neuroimaging
Background:
- Premature infants are at risk for brain injury.
- Intraventricular hemorrhage (IVH) is a common complication in premature neonates.
- Grade III IVH is associated with significant neurological sequelae.
Purpose of the Study:
- To assess the neurodevelopmental outcomes of premature infants with grade III intraventricular hemorrhage (IVH).
- To compare outcomes of infants with and without IVH at 12 months corrected age.
- To identify specific deficits associated with severe IVH in preterm infants.
Main Methods:
- Longitudinal follow-up of premature infants (birth weight ≤1,750 gm) until 12 months corrected age.
- Inclusion of infants with confirmed grade III IVH (CT-scans) and a control group without IVH.
- Multidisciplinary neurodevelopmental assessments including neurologic exams, hearing, speech, language, Bayley Scales, and evoked response studies.
Main Results:
- Eight of ten survivors with grade III IVH exhibited significant neurodevelopmental deficits, predominantly motor impairments.
- Only three of ten control infants (without IVH) showed suspicious or abnormal assessments.
- Grade III IVH is linked to widespread neurological damage in premature infants.
Conclusions:
- Premature infants surviving grade III intraventricular hemorrhage are at high risk for long-term neurodevelopmental deficits.
- A comprehensive, multidisciplinary evaluation is essential for identifying the full spectrum of impairments.
- Further research on all degrees of IVH is needed to understand its complete impact on development.
Abstract:
To determine the developmental outcome of premature infants weighing 1,750 gm or less at birth and who had grade III intraventricular hemorrhage (IVH), we followed up ten infants with IVH confirmed by computed tomography (CT) and ten CT-negative control infants until they were 12 months corrected age. The infants were evaluated at three-month intervals with neurologic examinations; hearing, speech, and language assessments; Bayley testing; and evoked response studies. Normal criteria were defined in each area. Eight of the ten grade III IVH survivors had identifiable defects, with a predominance of motor deficits, as assessed by two or more parameters. Only three of the ten patients without IVH had two or more suspicious or abnormal assessments. Infants with grade III IVH may have widespread damage. A multidisciplinary approach to evaluating these patients is mandatory to determine the full extent of various deficits. Similar studies of infants with all degrees of IVH may help to define its full impact on their long-term development.
