Abstract
BACKGROUND: Intraventricular haemorrhage (IVH) is one of the key risks for long-term neurodevelopmental issues. There remains controversy over the impact low-grade IVH has on the long-term outcome of premature infants. This study describes the long-term neurodevelopmental impact of Grade I and II IVH in former preterm infants in the early school years. METHODS: This is a retrospective cohort analysis from one tertiary neonatal intensive care unit (NICU) in Australia including all infants born at <30 weeks' gestation and admitted to the NICU between 2006 and 2013 with complete ultrasound reports and follow-up results. Results of standardised tests for neurodevelopmental outcomes at 5 and 8 years were compared between infants who suffered mild IVH and infants who had normal head ultrasounds. RESULTS: During the study period, 491 infants <30 weeks gestation were admitted; 275 patients had full follow-up data available. We found no significant difference in examined outcomes at 5- and 8-year follow-up. CONCLUSION: Mild IVH does not affect cognitive, motor and academic outcomes at school age.
