While suturing a wound, you opt to use lidocaine with epinephrine. The rationale for your choice is:
- an increase in the absorption of the lidocaine
- an increase in the diffusion of the lidocaine into the nerve's myelin sheath
- an increase in the blood flow to the area of injection
- an increase in the duration of anesthesia
- 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
