Introduction
Bleeding from the nose most commonly occurs when tiny blood
vessels inside the nostrils are ruptured, either by a blow to the
nose, or as a result of sneezing, picking or blowing the nose.
Nosebleeds may also occur as a result of high blood pressure.
A nosebleed can be dangerous if the casualty loses a lot of
blood. In addition, if bleeding follows a head injury, the blood
may appear thin and watery. The latter is a very serious sign
because it indicates that the skull is fractured and fluid is
leaking from around the brain.
Your aims
- To control blood loss.
- To maintain an open airway.
Treatment
- Ask the casualty to sit down.
- Advise them to tilt their head forwards to allow the blood to
drain from the nostrils.
- Ask the casualty to breath through their mouth (this will also
have a calming effect) and to pinch the soft part of the nose.
- Reassure and help if necessary.
- Tell the casualty to keep pinching their nose.
- Advise them not to speak, swallow, cough, spit or sniff because
this may disturb blood clots that may have formed in the nose.
- After 10 minutes, tell the casualty to release the pressure. If
the bleeding has not stopped, tell her to reapply the pressure for
two further periods of 10 minutes.
- Once the bleeding has stopped and with the casualty still
leaning forwards, clean around their nose with lukewarm water.
- Advise the casualty to rest quietly for a few hours. Tell them
to avoid exertion and in particular, not to blow their nose,
because these actions will disturb any clots.
Caution
- Do not let the head tip back; blood may run down the throat
inducing vomiting.
- If bleeding stops and then restarts, tell the casualty to
reapply pressure.
- If the nosebleed is severe, or if it lasts longer than 30
minutes in total, take or send the casualty to hospital in the
treatment position.
