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-
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
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.
