[Local anesthetics (LA). Adverse reactions from the use of LA (IV)]

Most common and significant adverse reactions directly attributable to the administration of local anesthetics which occur in dental practice are discussed. Both most severe systemic reactions--uncommonly found--and local reactions--of lesser importance--are reviewed. Tolerance, subtoxic doses and general toxicity of these drugs, as well as toxicity on specific organs are studied, as too are the prophylactic and therapeutic measures which need to be adopted according to the particular case. It is mandatory for the dental surgeon to have available equipment for resuscitation--mask and reservoir bag for assisted ventilation--equipment for fluid infusion, adrenaline, steroids, antihistamines, airways and suction equipment.
