Epistaxis

Question 1

What

Answer 1

Bleeding usually originates from Kiesselbach’s plexus, which is located in Little’s area. This is an area of the nasal mucosa at the front of the nasal cavity that contains a lot of blood vessels. When the mucosa is disrupted and the blood vessels are exposed, they become prone to bleeding.

TOM TIP: Little’s area (the area most affected by Little fingers picking noses) is a popular topic in exams. Remember the name of this area as examiners like to ask, “what is the most likely location of the bleeding?”

Question 2

Present

Answer 2

Bleeding is usually unilateral. Bleeding from both nostrils may indicate bleeding posteriorly in the nose. Posterior bleeding presents a higher risk of aspiration of blood.

Question 3

Treat

Answer 3

Nosebleeds will usually resolve without needing any medical assistance. Recurrent and significant nosebleeds might require further investigation to look for an underlying cause, such as thrombocytopenia or clotting disorders.

You may have to advise patients on how to manage a nosebleed in an exam:

Sit up and tilt the head forwards (tilting the head backwards is not advised as blood will flow towards the airway)
Squeeze the soft part of the nostrils together for 10 – 15 minutes
Spit out any blood in the mouth, rather than swallowing

When bleeding does not stop after 10 – 15 minutes, the nosebleed is severe, bleeding is from both nostrils, or haemodynamically unstable, patients may require hospital admission. Treatment options are:

Nasal packing using nasal tampons or inflatable packs
Nasal cautery using silver nitrate sticks

After treating an acute nosebleed, consider prescribing Naseptin nasal cream (chlorhexidine and neomycin) four times daily for 10 days to reduce any crusting, inflammation and infection. This is contraindicated in peanut or soya allergy.
