Abstract
Purpose of Review: This evidence-based systematic review evaluated the safety of ketamine as regard the potential to provoke epilepsy to help better guide anesthesiologists in their practice. Recent findings Ketamine, originally developed as a dissociative anesthetic, has gained attention for its potential therapeutic applications in various medical conditions, including epilepsy. Ketamine is generally well-tolerated and widely used in anesthesia, however, conflicting data are confusing the anesthesiologists regarding the potential risk of seizures associated with its use. The literature that claimed the proepileeptic property are inconsistent and the mechanism of action is unclear. Moreover, the case reports had been in same certain contexts, such as procedural sedation where ketamine was used as a single agent. On the other hand, the retrospective data analysis confirmed the positive role ketamine plays as antiepileptic agent. Summary Many studies have shown promising results for the use of ketamine as antiepileptic agent. In case of epileptic patients, there is no contraindication for using ketamine, however, combining with benzodiazepine or propofol may enhance the safety.

Ketamine as advanced second-line treatment in benzodiazepine-refractory convulsive status epilepticus in children. Epilepsia 2023; 64:797-810. [PMID: 36792542 DOI: 10.1111/epi.17550] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 02/11/2023] [Accepted: 02/13/2023] [Indexed: 02/17/2023]
Abstract
Status epilepticus (SE) is one of the most common neurological emergencies in children. To date, there is no definitive evidence to guide treatment of SE refractory to benzodiazepines. The main objectives of treatment protocols are to expedite therapeutic decisions and to use fast- and short-acting medications without significant adverse effects. Protocols differ among institutions, and most frequently valproate, phenytoin, and levetiracetam are used as second-line treatment. After failure of first- and second-line medications, admission to the intensive care unit and continuous infusion of anesthetics are usually indicated. Ketamine is a noncompetitive N-methyl-D-aspartate receptor antagonist that has been safely used for the treatment of refractory SE in adults and children. In animal models of SE, ketamine demonstrated antiepileptic and neuroprotective properties and synergistic effects with other antiseizure medications. We reviewed the literature to demonstrate the potential role of ketamine as an advanced second-line agent in the treatment of SE. Pharmacological targets, pathophysiology of SE, and the receptor trafficking hypothesis are reviewed and presented. The pharmacology of ketamine is outlined with related properties, advantages, and side effects. We summarize the most recent and relevant publications on experimental and clinical studies on ketamine in SE. Key expert opinion is also reported. Considering the current knowledge on SE pathophysiology, early sequential polytherapy should include ketamine for its wide range of positive assets. Future research and clinical trials on SE pharmacotherapy should focus on the role of ketamine as second-line medication.
