Lower concentrations of local anesthetics are typically used for infiltration anesthesia.

Variation in local anesthetic dose depends on the procedure, the degree of anesthesia required, and individual patient circumstances. Use of a reduced dose is indicated in the following patients:

  • Debilitated or acutely ill patients

  • Very young children or geriatric patients

  • Patients with liver disease, atherosclerosis, or occlusive arterial disease
