Vasoconstrictors will counteract the vasodilating effects of the local anesthetic agent. You will recall that most local anesthetic agents have a vasodilating effect on the vascular bed. You will also recall that when vasodilation occurs, it increases the rate of absorption of the local anesthetic into the blood, which will:
consequently decrease the duration of pain control due to quicker diffusion of the local anesthetic out of the vessel, which will:
Additionally, the increased blood flow at the site can cause increased bleeding at the site the local anesthesia was administered. Therefore, a vasoconstrictor is needed to counteract these effects.
