Short-term local anaesthetic injected into
tissues or applied to skin. It is effective
for brief, invasive procedures such as dental
care or insertion of a cannula (small tube)
into a vein. Temporary paralysis (to prevent
involuntary movement during eye surgery, for
example) can be achieved by injection
directly into the nerve serving the region.
Rapidly absorbed by mucous membranes (lining
tissues), lignocaine may be sprayed into the
nose or throat to allow comfortable insertion
of a viewing instrument during endoscopy. Its
action makes it a potent anti-arrhythmia drug
as well: given intravenously during or
following a heart attack, it reduces the risk
of irregular contractions of the ventricles.
