Convulsions with propofol: a rare adverse event.

Area of Science:

• Anesthesiology
• Neuroscience
• Pharmacology

Background:

• Propofol is a widely used intravenous anesthetic agent.
• Adverse reactions, including seizure-like phenomena, have been anecdotally reported with propofol administration.
• The proconvulsant or anticonvulsant properties of propofol remain a subject of debate.

Observation:

• A 50-year-old patient experienced generalized convulsions seconds after propofol administration for laparoscopic cholecystectomy.
• The convulsions resolved with intravenous thiopentone and midazolam.
• The patient remained hemodynamically stable, and the surgery proceeded uneventfully.

Findings:

• Postoperative evaluations, including neurological examination, serum electrolytes, and head CT scans, were normal.
• There was no postictal phase observed.
• This case highlights a rare but serious adverse event associated with propofol.

Implications:

• The exact pathophysiological mechanisms underlying propofol-induced neuroexcitatory symptoms are not fully understood.
• The transitionary states of consciousness during anesthesia induction or emergence may represent a vulnerable period for such reactions.
• Further research is needed to elucidate the neurobiology of propofol's effects on neuronal excitability.
