[Local anesthetics with elderly patients].

Abstract

When choosing local anesthetics, risk factors such as underlying diseases, use of other medications and allergies have to be taken into consideration. Systematic complications might occur if a specific limit in the plasma concentration is exceeded. Articaine and prilocaine are metabolized extrahepatically. In case of an absolute contraindication for vasoconstrictors, the use of mepivacaine, bupivacaine or articaine is recommended.
