Answer

Local Anesthetics

Local anesthetic agents are used to increase patient comfort during the procedure.

Lidocaine and epinephrine (Lignospan Forte, Xylocaine with Epinephrine)

Lidocaine is an amide local anesthetic used in a 0.5-1% concentration in combination with bupivacaine (50:50 mixture). This agent inhibits depolarization of type C sensory neurons by blocking sodium channels. Epinephrine prolongs the duration of the anesthetic effects from lidocaine by causing vasoconstriction of the blood vessels surrounding the nerve axons.

Bupivacaine (Marcaine, Sensorcaine)

Bupivacaine 0.25% may be used in combination with lidocaine plus epinephrine (50:50 mixture). It decreases permeability to sodium ions in neuronal membranes. This results in the inhibition of depolarization, blocking the transmission of nerve impulses.
