Novocaine is used in surgery and spinal anesthesia too.
Novocaine
is usually injected into tissue, a nerve trunk, next to a nerve, or even into
the spinal canal. What it does is it helps prevent the start of nerve impulses
by acting on the neuronal cell membrane. Nerve impulses are conducted by the
exchange of sodium and potassium ions through the cell membrane. Novocaine helps
to change the vulnerability of the cell membrane to sodium ions, therefore
changing the positive and negative ions of the membrane, and the way that it
behaves towards a nerve impulse. As the effect of the anesthetic increases, the
ingression for the electrical stimulation increases and conduction of the nerve
impulse decreases. And eventually the nerve conduction is totally blocked, so
that there is a loss of feeling in the area of which the doctor is going to
work. Novocaine is absorbed very quickly and starts to kick-in in about two to five
minutes, and the duration of the anesthesia usually last for one to two hours.
