Subependymal germinal matrix hemorrhage in full-term neonates
Pediatrics
|April 1, 1985
Summary
Intracranial hemorrhage, specifically subependymal germinal matrix hemorrhage, was detected in 4.6% of healthy newborns via cerebral ultrasonography. Lower gestational age and birth weight were associated with this condition.
Area of Science:
- Neonatal Medicine
- Pediatric Neurology
- Diagnostic Imaging
Background:
- Intracranial hemorrhage is a significant concern in newborns.
- Subependymal germinal matrix hemorrhage is a common type of neonatal brain injury.
Purpose of the Study:
- To determine the prevalence of intracranial hemorrhage in healthy, full-term newborns.
- To identify risk factors and associated conditions of subependymal germinal matrix hemorrhage.
Main Methods:
- Cerebral ultrasonography was performed on 505 healthy newborns within 72 hours of birth.
- Sonographic findings were analyzed, and infants with and without hemorrhage were compared.
Main Results:
- Intracranial abnormalities were detected in 4.6% of neonates.
- Subependymal germinal matrix hemorrhage was the most common finding.
- Infants with hemorrhage had significantly lower gestational age and birth weight, and were more likely to be small for gestational age, vaginally delivered, and black.
Conclusions:
- Subependymal germinal matrix hemorrhage occurs in a small percentage of healthy newborns.
- Lower gestational age, birth weight, and specific demographic factors are associated with this condition.
