Topic Overview
A
puncture wound
is a forceful injury caused by a sharp, pointed object that
penetrates the skin. A puncture wound is usually narrower and deeper than a cut
or scrape. Many people accidentally get puncture wounds with household or work
items, yard tools, or when operating machinery. Most puncture wounds are minor,
and home treatment is usually all that is needed.
Sharp objects,
such as nails, tacks, ice picks, knives, teeth, and needles, can all cause
puncture wounds. Puncture wounds increase your risk for infection because they
are difficult to clean and provide a warm, moist place for bacteria to
grow.
Some punctures are done for
health reasons. For example, a puncture may be used by
a doctor to draw blood or to give fluid or medicines directly into a vein
(intravenous, or IV).
Health professionals
have an increased risk for needle-stick injuries. A puncture from a used needle
increases the risk of infection or for transmitting a blood-borne disease, such
as
hepatitis or
human immunodeficiency virus (HIV). Home treatment may
be all that is needed for puncture wounds from clean needles.
When
you have a puncture wound:
- Determine whether any part of the object that
caused the wound is still in the wound, such as a splinter or
lead (graphite) from a pencil.
- Determine
whether underlying tissues, such as blood vessels, nerves, tendons, ligaments,
bones, joints, or internal organs, have been injured by the
object.
- Clean the wound and remove any dirt or debris to prevent
infections, both
bacterial skin infections and
tetanus ("lockjaw").
- Determine if you
need a
tetanus shot.
