Serial aEEG recordings in a cohort of extremely preterm infants: feasibility and safety

INTRODUCTION: Amplitude-integrated EEG (aEEG) monitoring is increasing in the neonatal population, but the safety and feasibility of performing aEEG in extremely preterm infants have not been systematically evaluated. METHODS: Inborn infants 23(0/7) – 28(6/7) weeks gestation or birth weight 401–1000 grams were eligible. Serial, six-hour aEEG recordings were obtained from first week of life until 36 weeks postmenstrual age. Adverse events were documented, and surveys evaluated the impact of the aEEGs on routine care. Success of performing aEEGs according to protocol and aEEG quality were assessed. RESULTS: 102 infants were enrolled, with 755 recordings performed. 83% of recordings were performed according to schedule, and 96% were without adverse event. Bedside nurses reported no interference with routine care for 89% of recordings. 92% of recordings had acceptable signal quality. CONCLUSIONS: Serial aEEG monitoring is safe in preterm infants, with few adverse events and general acceptance by nursing staff.
