Sample item

In severe local-anesthetic systemic toxicity with cardiovascular instability, which adjunctive rescue treatment is recommended?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Intravenous lipid emulsion

Intravenous lipid emulsion is used as part of resuscitation for severe local-anesthetic systemic toxicity because it can help sequester highly lipophilic anesthetic drug molecules.

Option by option

  • A. Intravenous lipid emulsion (correct)

    Correct: lipid emulsion is a recognized adjunct in severe LAST resuscitation.

  • B. Oral glucose tablets

    Oral glucose is not appropriate for an unstable anesthetized patient.

  • C. Topical antibiotic cream

    Topical antibiotic cream has no role in systemic toxicity treatment.

  • D. Routine anticoagulation

    Anticoagulation does not reverse local-anesthetic toxicity.
