Etomidate and unpredicted seizures during electroconvulsive therapy.

Area of Science:

• Psychiatry and Anesthesiology
• Neuroscience
• Clinical Pharmacology

Background:

• Electroconvulsive therapy (ECT) is a well-established treatment for severe psychiatric disorders.
• Anesthesia, including inducing agents, is integral to modern ECT procedures.
• Propofol and methohexital are commonly used inducing agents, with etomidate being less frequently reported in this context.

Observation:

• This report details two distinct cases experiencing seizures shortly after etomidate induction during ECT.
• The occurrences were noted despite variations in patient demographics, psychiatric diagnoses, and specific treatment protocols.
• Seizure activity post-etomidate induction is an infrequently documented phenomenon, primarily appearing in anesthesia-focused literature.

Findings:

• Etomidate, an anesthetic induction agent, was associated with seizure activity in two separate ECT cases.
• The timing of seizures, occurring soon after etomidate administration, suggests a potential link.
• This observation contrasts with the typical understanding and reporting of etomidate's effects in the context of ECT.

Implications:

• Clinicians should be aware of the potential for etomidate to precipitate seizures during ECT.
• Further research is warranted to elucidate the mechanism and incidence of etomidate-induced seizures in ECT.
• This finding may inform anesthetic agent selection and patient monitoring protocols in ECT settings.
