Stab injuries caused by piece of broken glass

The small stab wounds that occur during everyday life are often caused by:
nails, needles, scissors, knives or piece of broken glass.

Sometimes the object responsible for the stab wound also stays in the wound.
This has to be removed during first aid treatment or later on by a physician. 

Stab wounds usually look harmless from the outside, but can also run deep.

When stab wounds happen, there is a risk that nerves and tendons as well as internal organs might be damaged. There may also be invisible bleeding. There is an increased risk of infection even with minor stab wounds – caused by thorns and splinters, for example – as pathogens penetrate the tissue together with the foreign body.

Remove smaller splinters that have penetrated the surface with forceps. Then disinfect the wound and cover it with a plaster or sterile wound dressing.

You may not remove larger foreign bodies and splinters yourself in cases where you cannot see how much they have penetrated the tissue. Blood vessels may be damaged and bleeding triggered.

As a first aid measure, cover the wound area and foreign bodies with a clean cloth.
Apart from small splinters, wounds need to be treated immediately by a physician.

You should also go and see a physician if you were not able to remove a splinter completely or when tissue has become inflamed.
So that eventual parts of a foreign body can be detected when you are X-rayed, take any bits of the foreign body you may have with you to the physician for reference purposes.
