摘　　要：BACKGROUND Seizures are one of the most common neurological complications encountered in the intensive care unit(ICU).They can occur in the background of exacerbation of a known neurological disease or secondary to non-neurological conditions such as sepsis and metabolic disturbances.However,there is a paucity of literature on the incidence and pattern of new-onset seizures in ICUs.AIM To study the incidence and patterns of new-onset seizures in patients admitted to the medical ICU.METHODS This was a prospective,multicenter,observational study performed in two tertiary care centers in Hyderabad,India over a period of 1 year.Patients upon ICU admission,who developed new-onset generalized tonic clonic seizures(GTCS),were enrolled.Those with a pre-existing seizure disorder,acute cerebrovascular accident,head injury,known structural brain lesions,or chronic liver disease were excluded as they have a higher likelihood of developing seizures.All enrolled patients were subjected to biochemical routines,radiological imaging of either computed tomography or magnetic resonance imaging,and other relevant laboratory tests as per clinical suspicion according to the protocol,and their data were recorded.Statistical analyses were conducted using descriptive statistics,χ^(2) tests,and linear regression.RESULTS A total of 61 of 2522 patients developed GTCS.Among all etiologies of seizures,metabolic causes were most frequent(35%)followed by infective causes(27%)and others(new-onset structural,drug withdrawal,druginduced,toxicology-related,and miscellaneous factors).Logistic regression analysis showed that increased sodium and calcium levels were associated with a lower likelihood of developing seizures.CONCLUSION This study identified the etiology of new-onset seizures developing in critically ill patients admitted to the ICU.These findings highlight the need for targeted monitoring of those at risk of developing seizures.
