Abstract: This article explores the factors leading to brain injury in children with patent ductus arteriosus (PDA) based on ultrasound cerebral blood flow parameters. 207 premature infants with PDA were divided into a non brain injury group (148 cases) and a brain injury group (59 cases) as the study subjects. Compare the clinical data and cerebral blood flow parameters of two groups of research subjects, and analyze the risk factors that may cause brain injury. The efficacy of combining clinical indicators and cerebral blood flow parameters in predicting the occurrence of brain injury. Build a column chart model and validate it. The results showed that birth weight, chorioamnionitis, 5-minute Apgar score, middle cerebral artery resistance index (RI), and anterior cerebral artery RI were all influencing factors for the occurrence of brain injury in premature infants with PDA (OR>1, P<0.05). The column chart prediction model has good discrimination, accuracy, and effectiveness. The combination of cerebral blood flow parameters and clinical indicators has higher diagnostic efficacy in predicting brain injury.
