P.075 EEG features reflecting the neurodevelopmental assessment at term equivalent age in preterm born infants

Background: In Canada, 7% of children are born preterm between 29 and 36 weeks gestational age (GA). Electroencephalography (EEG) provides a bedside evaluation brain activity, yet the clinical significance several EEG patterns requires further study. The goal this study is to determine features at term equivalent (TEA) that correlate with neurodevelopmental TEA in infants 29-36 GA. Methods: Prospective cohort GA 1 hour recording TEA. discontinuity index (proportion <25mcV amplitude) spectral power densities were calculated as well mean maximum values interburst intervals. At TEA, neurodevelopment was evaluated using General Movement Optimality Score (GMOS) . Linear regression analyses used evaluate association assessment. Results: Eighty-two (median 33.6 weeks) included (47 males). Median GMOS 29.0 (IQR 24.3-35.0). A greater associated reduced (B -6.85; 95% CI -12.13,-1.57; p=0.012). Conclusions: more abnormal Ongoing longitudinal assessments needed better prognostic potential EEG.
