Status epilepticus in children: a five-year experience at Aga Khan University Hospital.

OBJECTIVE

Status epilepticus is an under diagnosed entity in Pakistan. It is a potentially reversible condition but has a high mortality, if it is not recognized and managed on time. The purpose of this study was to determine the clinical profile and the relationship of mortality of status epilepticus with its known risk factors.

METHODS

This was a retrospective study. Medical records of all the patients admitted in the last five years (1998-2002) with a diagnosis of status epilepticus (ICDcode 345.30, 345.31) were reviewed. Data was recorded on a Performa and analyzed by using the statistical programme SPSS, chi square and Fischer exact test.

RESULTS

The total number of patients were twenty-four. Sixteen patients were males (66.7%). Mean age was fifty-eight months and mean duration of hospital stay 5.5 days (range 2 to 22days). Eight patients were diagnosed to have epilepsy. Four (16.7%) had a previous history of status epilepticus. Three patients presented with status epilepticus for the first time without any previous history of seizures. Ten patients required midazolam infusion (41.7%) and out of these 3 (12.5%) were also given thiopentone infusion to control the seizures. Nine patients were shifted to the ICU for ventilation and control of seizures. Mortality in our study was 25%. Risk factors for mortality included age less than or equal to one year, abnormal MRI, type of the status epilepticus and the total duration of status epilepticus. No significant relationship was found with any of the known risk factors

CONCLUSION

Status epilepticus is a neurological emergency. A very high mortality was seen in our study. No risk factors were identified for this high mortality.
