Abstract
Almost after a century of its introduction, local anesthesia remains one of the most important methods to relieve pain in perioperative medicine. They can find their uses in different forms, i.e. as part of general anesthesia,in  regional anesthesia,in plexus block or as local infiltration anesthesia itself. Many local anesthetics have been introduced since 1884, from cocaine, which was administered on eye as a local anesthetic to relatively newer drugs like ropivacaine, levo-bupivacaine, etc.; having their own advantages and disadvantages.
