Why is sodium bicarbonate added to lidocaine?
Lidocaine with epinephrine is very acidic compared with subcutaneous tissue. The addition of 8.4% bicarbonate at a volume ratio of 1 mL:10 mL neutralizes the acidity of 1% lidocaine with 1:100,000 epinephrine. Neutralizing the pH of lidocaine has been previously shown to decrease the pain of injection.
