A patient treated with a local anaesthetic during a procedure develops seizures, severe hypotension and a widening QRS complex. Which rescue treatment is associated with local anaesthetic systemic toxicity?
Correct answer: A. Intravenous lipid emulsion
- A. Intravenous lipid emulsion
- B. Intravenous vitamin K
- C. Oral activated charcoal alone
- D. Intravenous acetylcysteine
Explanation
Intravenous lipid emulsion is used in severe local anaesthetic systemic toxicity, together with airway support and seizure management. Vitamin K reverses warfarin, acetylcysteine treats acetaminophen poisoning, and charcoal alone cannot manage cardiovascular collapse.
