Nosebleeds in Children: Causes, First Aid and When ENT Cautery May Help

Nosebleeds are very common in children. Most are not serious, but they can be messy, frightening and disruptive, especially when they happen at night, at school or repeatedly over several weeks.

The medical term for a nosebleed is epistaxis. In children, most nosebleeds come from the front of the nose, where small blood vessels sit close to the surface. These vessels can become irritated by nose picking, dry air, colds, allergies or minor trauma.

At Hampshire ENT Clinics, children with recurrent nosebleeds can be assessed by Miss Eleanor Sproson, Consultant ENT Surgeon and Lead Paediatric ENT Consultant at Portsmouth Hospitals NHS Trust.

Quick answer: when should a child with nosebleeds see ENT?

ENT assessment is recommended if nosebleeds are frequent, heavy, difficult to stop, mainly from one side, associated with nasal blockage or discharge, or affecting school and sleep. Urgent medical help is needed if bleeding is severe, follows significant injury, or the child seems unwell, pale, faint or short of breath.

Why children get nosebleeds

Most childhood nosebleeds are anterior nosebleeds, meaning they come from the front part of the nasal septum. This area contains a network of delicate blood vessels. Small injuries or irritation can make them bleed.

Common triggers include nose picking, rubbing the nose, dry nasal lining, colds, allergic rhinitis, sneezing, minor knocks and crusting inside the nose. Less commonly, recurrent nosebleeds may be linked to a bleeding tendency, medication, nasal foreign body or structural nasal issues.

First aid for a nosebleed

Parents should keep the child calm, sit them upright and lean them slightly forward. Pinch the soft part of the nose firmly, not the hard bony bridge. Maintain steady pressure for 10 to 15 minutes without repeatedly checking.

The child should breathe through the mouth and spit out blood rather than swallowing it, as swallowed blood can make children feel sick. After the bleed stops, avoid nose blowing, picking or strenuous activity for a period of time.

Common mistakes

A common mistake is leaning the child backwards. This can cause blood to run into the throat and stomach. Another mistake is pinching the bridge of the nose rather than the soft front part where most childhood nosebleeds start.

Repeatedly releasing pressure to check whether the bleeding has stopped can also prevent clot formation.

When nosebleeds keep recurring

Recurrent nosebleeds may happen because the same small vessel keeps reopening. The lining of the nose may be dry, crusted or inflamed. Allergic rhinitis can contribute because itching and rubbing irritate the nose.

A child with unilateral discharge, bad smell or persistent one-sided symptoms should be assessed because a nasal foreign body can occasionally be the underlying cause.

What happens at an ENT appointment?

The consultant will ask about frequency, duration, side of bleeding, triggers, bruising, family history, medication and any nasal blockage or discharge. The nose is examined to look for prominent vessels, crusting, inflammation or other causes.

In many children, the source is visible at the front of the nose. If the child is old enough and cooperative, treatment can be planned in clinic or as a minor procedure depending on circumstances.

What is nasal cautery?

Nasal cautery treats a prominent bleeding point, commonly using silver nitrate. It aims to seal the small vessel causing recurrent bleeding. It is generally used when a visible bleeding point is identified and conservative measures have not worked.

Cautery is not suitable for every child and should be performed carefully. Aftercare usually involves keeping the nose moist and avoiding picking or rubbing while the lining heals.

Can moisturising treatments help?

Yes. Many children improve with simple measures such as nasal moisturising ointment, saline spray, allergy treatment where needed, and avoiding nose picking. Treating the nasal lining can reduce crusting and irritation.

When to book an appointment

Parents should consider paediatric ENT review if nosebleeds are recurrent, disruptive, difficult to stop or associated with other nasal symptoms. Hampshire ENT Clinics offers consultant-led assessment for children with nosebleeds and other paediatric ENT concerns.

When are nosebleeds urgent?

Seek urgent help if bleeding is heavy, will not stop, follows significant injury, or the child is pale, faint, breathless or unwell.

Can allergies cause nosebleeds?

Yes. Allergic rhinitis can cause itching, rubbing, sneezing and inflammation, all of which can contribute to bleeding.

What is silver nitrate cautery?

It is a treatment used to seal a visible bleeding point in the nose.

Is nasal cautery painful?

It can sting or feel uncomfortable briefly. Suitability depends on the child’s age, cooperation and the appearance of the nose.
