Introduction. Seizures are the most frequent neurological urgency in pediatrics, becoming a vital urgency, especially when there are convulsive states that merit surveillance in a pediatric intensive care unit (PICU).

Materials and methods. The study population was a total of 60 patients under the age of 18 hospitalized in PICU in a hospital located in Cartagena-Colombia. The resulting data were calculated univariate statistics of central tendency and proportions, such as univariate and bivariate frequency tables.

Results. A population of 60 pediatric patients with a mean age of 3.85 years was obtained, having a history of epilepsy in 64.81% and 23.33% in cerebral palsy. The most common comorbidity was meningeal infection with 25.71%. Patients with a history of epilepsy, the most widely used outpatient medication was valproic acid with 48.33%, followed by levetiracetam 26.67% and carbamazepine 13.33%. Within the study population, 83.33% presented convulsive status, with the generalized clonic tonic crisis being the most frequently described type of crisis with a percentage of 88%, the most used anticonvulsant drugs for jugular crisis, midazolam was found with 98.33%. 95% left the institution alive and 5% died.

Conclusions. The main causes of epileptic status are acute brain injury, atypical febrile seizures, epilepsy and degenerative diseases, which is consistent with what has been described in the literature, the most used anticonvulsant medications in PICU are midazolam in the first stay and valproic acid In second stay.
