Background
Disorder of consciousness (DOC) is a state of prolonged altered consciousness, which can be categorized into coma, vegetative state, or minimally conscious state based on neurobehavioral function [1]. The causes of DOC are diverse and can include cerebrovascular disorders, cardiac conditions, drug intoxication, hypoglycemia, infections, as well as psychiatric abnormalities [2]. DOC can lead to irreversible sequelae if early intervention is not provided. Therefore, early diagnosis and treatment are of paramount importance [3]. Indeed, diagnosing DOC during the perioperative period can be challenging due to the effects of anesthesia. We encountered a patient who developed impaired consciousness after surgery, following awakening and extubation. Based on his clinical presentation, a first episode of non-convulsive status epilepticus (NCSE) was considered as the cause of his DOC. Here, we provide a report of this case along with a literature review to support our findings and contribute to the existing knowledge on this topic. The patient’s written, informed consent was obtained for publication of this case report.
