Seizures in the critically ill

Area of Science:

• Critical Care Medicine
• Neurology
• Neurocritical Care

Background:

• Critically ill patients in the ICU may develop seizures due to various factors including systemic illness, primary neurological conditions, or medication side effects.
• Seizures in this population can range from subtle symptoms to overt convulsive activity and may rapidly progress to status epilepticus.
• Status epilepticus (SE) in critically ill patients is associated with significant morbidity and mortality, often requiring complex management strategies.

Purpose of the Study:

• To highlight the challenges and critical importance of recognizing and treating seizures in critically ill patients.
• To emphasize the potential for seizures to escalate to status epilepticus (SE) in the intensive care unit (ICU) setting.
• To underscore the necessity of prompt intervention with antiepileptic drugs (AEDs) for favorable outcomes.

Main Methods:

• Review of clinical presentations and potential etiologies of seizures in critically ill patients.
• Discussion of the pathophysiology and complications of status epilepticus (SE) in the ICU.
• Emphasis on the diagnostic and therapeutic challenges in neurocritical care settings.

Main Results:

• Seizures in critically ill patients can be secondary to systemic or neurological issues and present with diverse symptoms.
• Untreated seizures can evolve into generalized convulsive or nonconvulsive status epilepticus (SE), carrying high mortality risks.
• Refractory SE may necessitate intensive treatments including anesthetics and narcotics.

Conclusions:

• Prompt recognition and initiation of antiepileptic drugs are paramount for successful treatment of status epilepticus (SE) in critically ill patients.
• Effective management of seizures in the ICU requires a high index of suspicion and rapid intervention.
• Attentiveness to seizure activity is critical for preventing severe neurological injury and improving survival rates in the neurocritical care setting.
