Neonatal seizures: Predictors of adverse outcome.

CONTEXT: Early detection of predictors of adverse outcome will be helpful for neonatologists to plan management, follow up and rehabilitation in advance so that neurological disability can be minimised.

AIMS: The purpose of this study was to determine the factors affecting the adverse outcome of neonatal seizures.

SETTINGS AND

DESIGN

This is a prospective study conducted in the neonatal unit of a tertiary care hospital. One hundred and eight newborns consecutively admitted with seizures were included in this study.

MATERIALS AND

METHODS

Data was collected regarding perinatal history and seizure and evaluated for etiology. We conducted a retrospective analysis to identify the factors associated with adverse outcome after neonatal seizures.

STATISTICAL ANALYSIS USED: Chi-square test with degree of freedom = 1 was used to find the variables significantly associated with adverse outcome (P < 0.05).

RESULTS

Gestational age, birth weight, Apgar score at 5 min, seizure onset <24 hrs, status epilepticus, radiological findings and EEG findings were significantly associated with outcome.

CONCLUSION

Mortality and severe neurological impairment after neonatal seizure is associated with prematurity, LBW, low Apgar score at 5 min, etiologies like meningitis, sepsis, severe HIE, brain malformations, grade 3 or 4 IVH or intracranial haemorrhage, seizure onset <24 hours, presence of status epilepticus, severely abnormal radiological and EEG findings.
