Pharmacology of Local Anesthetics
The development of local anesthetics dates to the first use by the Incas of Peru, using cocaine for its medicinal properties. They treated headaches with trepanation or by burrowing holes in the skull with chewed cocaine as the local anesthetic. Today, the use of local anesthetics by anesthesia providers has gained increasing popularity, traditionally in both obstetric and regional anesthesia. This chapter will focus on the types of local anesthetics, dosing and mechanism of action, indications with clinical pearls, and drug interactions/toxicity profile.
