RESUMO
OBJECTIVE: To describe the neurological outcome of newborns with seizures. METHOD: Cohort study with newborns prospectively followed. Perinatal characteristics and etiological screening were related to outcome in a regression model. RESULTS: During the study 3,659 newborns were admitted and 2.7% were diagnosed as having seizures. Hypoxic ischemic encephalopathy (51%) was the etiology more frequently associated to seizures and also to postneonatal epilepsy (53%). In the follow up 25 died during the acute neonatal illness and 9 during the first years of life, 19 were diagnosed as having post neonatal epilepsy, 35 had developmental delay and 11 an association among this two comorbidities. A significant association between abnormal postnatal EEG and neuroimaging to developmental delay (p=0.014, p=0.026) was observed. The group of newborns that had seizures presented an increased risk of developing epilepsy compared to newborns from the same cohort without seizures (19.3/100 vs. 1.8/100, p<0.001). CONCLUSION: In this study neonatal seizures predominated in term newborns with perinatal asphyxia an elevated perinatal mortality and post neonatal morbidity was observed. The follow up showed an increased risk for developing postnatal epilepsy and developmental delay.

OBJECTIVE: To describe the neurological outcome of newborns with seizures. METHOD: Cohort study with newborns prospectively followed. Perinatal characteristics and etiological screening were related to outcome in a regression model. RESULTS: During the study 3659 newborns were admitted and 2.7 percent were diagnosed as having seizures. Hypoxic ischemic encephalopathy (51 percent) was the etiology more frequently associated to seizures and also to postneonatal epilepsy (53 percent). In the follow up 25 died during the acute neonatal illness and 9 during the first years of life, 19 were diagnosed as having post neonatal epilepsy, 35 had developmental delay and 11 an association among this two comorbidities. A significant association between abnormal postnatal EEG and neuroimaging to developmental delay (p=0.014, p=0.026) was observed. The group of newborns that had seizures presented an increased risk of developing epilepsy compared to newborns from the same cohort without seizures (19.3/100 vs. 1.8/100, p<0.001).

OBJETIVO: Avaliar o prognóstico neurológico de neonatos com crises convulsivas. MÉTODO: Estudo prospectivo, realizado em coorte de neonatos provenientes de hospital terciário. As características clínicas perinatais e os resultados de exames complementares foram correlacionados com prognóstico através de modelo de regressão logística. RESULTADOS: Durante o estudo 3659 neonatos foram internados, sendo que 101 apresentaram crises convulsivas (2,7 por cento). A encefalopatia hipóxico-isquêmica foi a etiologia mais frequentemente associada às crises (51 por cento). O seguimento evidenciou 25 óbitos no período neonatal e 9 durante os primeiros anos de vida, 19 lactentes desenvolveram epilepsia, 35 atraso no desenvolvimento e 11 associação entre os dois desfechos. O modelo de regressão logística aplicado mostrou associação significativa entre EEG pós neonatal anormal e neuroimagem anormal com atraso no desenvolvimento (p=0,014, p=0,026). Os neonatos em estudo, quando comparados aos demais da mesma coorte, que não apresentaram crises convulsivas tiveram maior probabilidade de desenvolver epilepsia (19,3/100 vs. 1,8/100, p<0,001). CONCLUSÃO: Neste estudo em que ocorreu predomínio de crises neonatais em neonatos a termo com asfixia perinatal, foi observada alta mortalidade perinatal e morbidade. O seguimento neurológico evidenciou elevado risco de desenvolvimento de epilepsia e/ou atraso no desenvolvimento neuropsicomotor.
