Question

What are the effects of high local anesthetic concentration on the cardiovascular system?

1) EKG changes
2) Treatment of cardiovascular collapse
3) Increased risk of toxicity
4) Decreased risk of toxicity

Answer 1

High local anesthetic concentration can have various effects on the cardiovascular system, including EKG changes, treatment of cardiovascular collapse, and increased risk of toxicity.

Step-by-step explanation:

High local anesthetic concentration can have several effects on the cardiovascular system.

1. EKG changes: High local anesthetic concentration can cause changes in the electrical activity of the heart, which can be seen on an electrocardiogram (EKG).
2. Treatment of cardiovascular collapse: In some cases, high local anesthetic concentration can lead to cardiovascular collapse, a life-threatening condition. Prompt medical intervention, such as administering intravenous fluids or medications, may be required to treat this condition.
3. Increased risk of toxicity: High local anesthetic concentration can increase the risk of toxicity, as more of the drug is present in the body. This can lead to symptoms such as dizziness, confusion, and seizures.
4. Decreased risk of toxicity: Contrary to the previous option, high local anesthetic concentration actually increases the risk of toxicity rather than decreases it.
