[Plasmatic value curves of mepivacaine in plexal anesthesia of the upper jaw, the spine of Spix and intraligamentary].

Abstract

To extend previous, studies, the authors analyzed plasmatic values of mepivacaine 5, 15, 30, 60, and 90 minutes following administration of the drug. Three routes of administration were used: intraligamentary, plexal, at the supramaxillary level and troncular, into the Spix spine. The results of the present study suggest that absorption of mepivacaine varies from patient to patient, depending on individual factors as hepatic metabolism of the drug.
