80-95% of cases bleeding originates from little's area on the anterior nasal septum - contains the Kiesselbach plexus of vessels - anastomosis of multiple arteries
Less commonly bleeding originates from branches of the sphenopalatine artery in the posterior nasal cavity
Demographics:
Very common
Common in children >2 years and becomes less likely after a child is >10 years
Posterior epistaxis is more common in adults, and tends to be seen in over 45s
Local causes of damage to blood vessels:
Trauma e.g. picking nose, fracture, FB, fall
Inflammation/infection e.g. rhinosinusitis, nasal polyps
Topical drugs e.g. cocaine, decongestants, steroids
Vascular e.g. hereditary haemorrhagic telangiectasia, granulomatosis with polyangiitis
Tumours
Nasal oxygen therapy - drying of nasal mucosa
More general causes of damage:
Clotting disorders - thrombocytopenia, haemophilia, Von Willebrand, leukaemia
Environmental - temperature, dust, chemicals
Systemic drugs - anticoagulants and antiplatelets
Atherosclerosis
Hypertension is common in people who present with epistaxis
Symptoms:
Bleeding usually unilateral
Suspect posterior bleed if - bleeding profuse, from both nostrils, bleeding site cannot be identified on speculum exam
Rarely bleeding loss is enough to cause anaemia and haemodynamic compromise - most likely if patient is older and frail
Can present with vomiting blood - swallowed blood rather than GI bleed
May be symptoms of underlying cause
Examination:
If able get patient to gently blow nose to clear old blood
Look for for bleeding point - looks like a small red dot (<1mm)
If history of trauma check for septal haematoma - collects between septal cartilage and perichondrium - needs urgent drainage as can lead to septal necrosis (perichondrium supplied blood to septal cartilage)
Investigations:
Only need bloods if suspect underling cause e.g. coagulation problem
Or if concerned about significant bleeding and want to check for anaemia
Acute epistaxis management:
Sit up, tilt head forward, mouth open
Pinch soft part of nose firmly and hold for 10-15 mins without releasing pressure (wont compress posterior bleed)
Once bleeding stopped consider topical antiseptic (naseptin) cream 4 times daily for 10 days to reduce crusting and vestibulitis
If can't use naseptin an alternative is mupirocin nasal ointment 2-3 times a day for 5-7 days
Admit to hospital if:
Haemodynamically compromised
Bleeding from posterior area of nose
If bleeding doesn't stop after 10-15 mins of nasal pressure may need:
Nasal cautery: topical anaesthetic spray, cauterize by lightly applying silver nitrate stick to bleeding point for 3-10 seconds
Nasal packing if cautery ineffective or bleeding point not seen - topical anaesthetic then pack (tampon, inflatable pack, ribbon gauze)
After bleeding stops:
Avoid activities that increase risk of re-bleeding for 24 hours:
Blowing/picking nose
Heavy lifting
Strenuous exercise
Lying flat
Drinking alcohol or hot drinks
If applying pressure, cautery and packing don't work:
Further specialist measures may be required
Formal packing under GA
Endoscopic assessment and electrocautery
Arterial ligation
Radiological arterial embolization
Tranexamic acid
Recurrentepisodes:
Consider investigating for underlying cause e.g. FBC and clotting
Refer to ENT if concerned about serious underlying cause e.g. tumours or telangiectasia
If patient not at risk of serious underlying cause then consider - topical treatments with naseptin or mupirocin, nasal cautery
If despite treatment remains recurrent then refer to ENT
main anatomy principles:
There is dual arterial supply from both the internal and externalcarotid arteries
Most bleeds originate anteriorly in the nasal cavity in Little's area within the Kiesselbach's plexus - area particularly vulnerable to dryness and trauma
The following clinical features may suggest a more serious underlying diagnosis.
