Methods: In this trial, 60 cases of premature infants admitted to the hospital from August 2022 to January 2024 were selected as the subjects of this study. The study used amplitude-integrated electroencephalography combined with magnetic resonance imaging to examine the changes in various aEEG indicators with gestational age and postnatal age, dividing them into: 3 days postnatal, 1 week postnatal, 2 weeks postnatal, and corrected gestational age of 40 weeks. At the same time, it combined the results of cranial magnetic resonance imaging (MRI) for preterm infants at corrected gestational age of 40 weeks, to evaluate the predictive value of early aEEG indicators for brain injury in preterm infants;At the same time, the results of infant intelligence development scale (CDCC) and Bailey Infant Development Scale (BSID) were evaluated at 1 year of age to compare the correlation between early aEEG results and MDI and PDI at 1 year of age. Results: The results of aEEG in preterm infants at 3 days, 1 week, 2 weeks and corrected gestational age of 40 weeks showed significant differences, and with the increase of age, the detection results of aEEG showed that the rate of abnormal brain electricity in preterm infants was decreasing, and close to the detection results of preterm infants at corrected gestational age of 40 weeks (P < 0.05);In the early aEEG results, the MDI, PDI and CDCC scores of normal, mild and severe patients decreased gradually with the severity at 1 year old, and there were differences (P < 0.05). The scores were inversely proportional to the aEEG. Conclusion: Amplitude integrated EEG combined with magnetic resonance imaging can monitor the brain function of premature infants at different gestational ages, understand the condition of preterm infants at different gestational ages, judge the severity, and evaluate the development of prognosis brain function.展开更多
