Local Anaesthetic effect of carticaine [Ultracaine] in comparison to lidocaine

ABSTRACT

The aim of this work was to study carticaine and its local anesthetic properties in comparison with lidocaine. The results revealed that in intravenous regional analgesia, the onset time and duration of analgesic action till full recovery were shorter with carticaine. There was no significant difference between the two groups in the quality of anesthesia and motor block. In spinal analgesia, both local anesthetics acted similarly, but the loss of tactile sensation and motor block began earlier with carticaine. In epidural analgesia, there was no difference between carticaine and lidocaine in the onset time and spread of analgesia or motor block. The duration of analgesia was longer with carticaine. In dental patients, the onset of analgesia with nerve block as well as infiltration anesthesia was quicker with carticaine as compared with lidocaine
