Local anesthesia

Reversible, localized elimination of pain sensation through surface, infiltration (or field block) anesthesia. The term is sometimes used synonymously with "regional anaesthesia".

• The following types of local anaesthesia are distinguished:
  • Surface anaesthesia
  • Infiltration anaesthesia
  • Field block anaesthesia
  • Tumescent anesthesia
  • Anaesthesia
  • Intravenous regional anaesthesia: In this procedure, LA are injected into the vein of a previously anaemic limb. Operations of up to 1 hour can then be performed on this limb (e.g. surgery for Carpatunnel syndrome).

"Hypersensitivity" (see local anesthetics below) to the preparation, blood clotting disorders, non-cooperative patients or children whose cooperation cannot be expected. Caution! Asking about intolerance of local anesthetics before each local anesthesia is necessary! Note: proarrythmic effect, especially with lidocaine, less with prilocaine.
