Question

You have assisted in the performance of a nerve block in the operating room. If the patient were to develop symptoms of LAST, when would you expect them to present?

A) Immediately
B) Within 5 minutes
C) Within 30 minutes
D) Any of the above
E) None of the above

Answer 1

Symptoms of LAST in a nerve block would typically present immediately after the injection and require immediate medical intervention.

Step-by-step explanation:

In the case of a nerve block, if the patient were to develop symptoms of LAST (local anesthetic systemic toxicity), the symptoms would typically present immediately after the injection.

LAST is a rare but serious complication that can occur when local anesthetic medication enters the bloodstream and affects the central nervous system. Symptoms can include seizures, cardiac arrhythmias, and changes in mental status.

If LAST is suspected, immediate medical intervention is necessary to address the symptoms and prevent further complications.
