Liposuction surgery under local anesthesia: limited blood loss and minimal lidocaine absorption.

A large volume of lidocaine with epinephrine can be administered in dilute concentrations into the subcutaneous space, resulting in minimal blood lidocaine levels. This allows large-volume, multiple-area liposuction to be done painlessly under local anesthesia with only oral and intramuscular sedation and analgesia. Other advantages include minimal blood loss, decreased patient morbidity and expense, and elimination of the risks of general anesthesia and intravenous anesthesia/sedation.
