The Daily PANCE and PANRE Question 9

While suturing a wound, you opt to use lidocaine with epinephrine. The rationale for your choice is:

  1. an increase in the absorption of the lidocaine
  2. an increase in the diffusion of the lidocaine into the nerve's myelin sheath
  3. an increase in the blood flow to the area of injection
  4. an increase in the duration of anesthesia
  5. a decrease in the risk of infection at the site of injection

Answer: D

An increase in the duration of anesthesia

Lidocaine with epinephrine both increases the duration of anesthesia and decreases blood flow to the area of injection-i.e. penis, nose, fingers, toes
