Why does local anaesthetic toxicity typically show central nervous system excitation, including seizures, before depression?
Local anaesthetics directly stimulate excitatory cortical neurons at all plasma concentrations
Adrenaline in the cartridge crosses the blood-brain barrier first
Inhibitory cortical neurons are blocked first, releasing excitatory pathways
Excitation results from hypoglycaemia caused by the drug
