To describe the implementation of the convulsion prevention room model for children with high fever among mothers with children under 5 years old at Thai Nguyen Pediatric Center of Thai Nguyen General Hospital in 2025.  Material and Methods: A cross-sectional descriptive study was conducted on 217 mothers with children under 5 years of age who sought examination and treatment at the Pediatric Center of Thai Nguyen General Hospital from January to December 2025.  Results: The proportion of mothers with good knowledge/ application of the model was 37.3%, while 62.7% demonstrated limited or insufficient knowledge/ application. Most knowledge indicators regarding febrile convulsions in children reached an average level, with correct response rates ranging from 64.1% to 93.5%. The proportion of mothers who correctly answered that febrile seizures may progress to epilepsy was 48.1%. The proportion who correctly identified febrile seizures as having a familial or genetic component was 42.9%. The proportion of mothers who correctly recognized that febrile seizures can occur suddenly and cannot be completely prevented was 35.5%. Most mothers had correct knowledge regarding measures to prevent febrile seizures in children with high fever, with rates exceeding 90%. However, only 25.3% of mothers correctly identified that giving children orange juice for rehydration and improving resistance is not appropriate. Mean while, 82.5% correctly recognized that when fever occurs, children should drink plenty of warm water/ORS solution or be breastfed frequently.  Conclusion: The proportion of mothers with accurate knowledge regarding the prevention of febrile seizures remains low. Therefore, further studies are needed to identify factors associated with correct knowledge in order to develop appropriate health education interventions for mothers.
