Injected anesthetics are often given with _____________ to minimize systemic absorption.

Injected anesthetics are frequently administered with epinephrine to minimize systemic absorption. Epinephrine, a vasoconstrictor, helps to narrow blood vessels in the area where the anesthetic is injected. This constriction reduces blood flow, which in turn decreases the rate at which the anesthetic enters the systemic circulation. By slowing the absorption of the anesthetic into the bloodstream, epinephrine helps prolong the anesthetic’s effect at the injection site and reduces the potential for systemic side effects.

Using epinephrine is a standard practice in local anesthetic procedures, as it enhances the anesthesia duration and improves the overall effectiveness of the local anesthetic while minimizing risks associated with excessive systemic absorption.
