Disability and Mortality in Convulsive Status Epilepticus in Children at 3 Months' Follow-Up: A Prospective Study from India.

Abstract

Background Convulsive status epilepticus (CSE) is a common neurological emergency with high mortality, morbidity, and poor quality of life. There is a paucity of follow-up studies from developing nations in pediatric age group. Objectives This article looks for clinico-etiological profile of CSE and estimates the immediate and short-term mortality in children with CSE and its predictive factors. Methodology This prospective longitudinal study was done at a tertiary care institute of Northern India. The patients between the ages of 1 and 16 years with CSE were enrolled after informed consent, they were observed in the hospital, and survived patients were followed till 3 months after discharge. Results A total of 200 patients (58% males) were enrolled. Acute symptomatic (63.5%) was the most common etiology. Twenty-five (12.5%) patients died during hospital stay; at discharge, 160 (80%) had good recovery and rest had a varying range of disability. The predictive factors for poor outcome were female gender, duration of CSE > 1 hour at presentation, generalized seizures, Glasgow Coma Scale < 8 at presentation, refractory status epilepticus, need for critical care support, and acute symptomatic etiology. On follow-up, two patients died at 1-month and one at 3-month follow-up, the cause of death was probably seizures in two patients and feed aspiration in one patient. Seven patients deteriorated from good recovery scoring to moderate disability during the time interval between first and second follow-up, none of them reported apparent repeat seizures. Conclusion Pediatric CSE is associated with immediate poor outcome; risk of death and new disabilities persist after discharge thus proper follow-up is essential.
