Introduction: Acute encephalopathy is one of the urgent

problems of childhood. According to the studies, the frequency

of seizures in acute encephalopathy was found to be between

19-28%. However seizures are common in cases with

acute encephalopathy, most of them are nonconvulsive(NCS).

These seizures can be easily overlooked without continous video-

EEG monitoring(cEEG).

In this study, the prognostic value of cEEG in determination

during early period in acute encephalopathy cases followed in

Pediatric intensive care unit(PICU).

Methods: This prospective study was carried out in Ege University

PICU. Twenty-four patients with GCS≤8 who were diagnosed

with acute non-traumatic/non-operative traumatic

encephalopathy were included in the study. The patients were

monitored for at least 24 hours. In the presence of electrografic

seizures, cEEG was extended till 48-72 hours.

All patients were evaluated with Modified Pediatric Cerebral

and Overall Performance Category Scale(PCOPCS) in terms of

morbidity before discharge from hospital.

Results: Of the 24 patients, 14 were female. From the point of

the etiology, head trauma was found in six patients, The other

causes were asphyxia, intoxication, uremic encephalopathy,

hepatic encephalopathy, metabolic disease.

During 24hour monitoring, eleven NCS were observed in four

cases. Eighteen percent of NCS was detected during the first

hour of cEEG and 82% of them developed within 24 hours.

NCSE was not observed in any patient. It was concluded that

the cEEG with 24 hours duration may be sufficient in cases with


In according to PCOPCS, 11 and 13 patients had good and bad

prognosis respectively.

Conclusion: cEEG is still gold standard for the detection of

nonconvulsive seizures. On the other hand there are some difficulties

for application of cEEG in intensive care units. Multidisciplinary

approach and cooperation are essential.
