Local anaesthesia of the laryngeal mucosa, Lidocaine acts by preventing the generation and conduction of nerve impulses. It prevents the increase in permeability of excitable membranes to sodium ions. Small, non-myelinated nerve fibres are more susceptible than are large fibres and the sensation of pain is first modality to be lost. Lidocaine is metabolised mainly in the liver and excreted via the kidneys. Approximately 95% is excreted via the form of various metabolites while 5% is excreted unchanged.
