Epistaxis Flashcards
AR the blood supply to the nose
also descending palatine down back of palate
What are the causes of epistaxis?
Idiopathic
Iatrogenic (surgery, topical spray, cocaine)
Traumatic (fracture, FB, picking)
Infection, inflammatory (rhinitis)
Malignancy (angiofibroma, carcinoma)
Anticoagulants
Coagulopathies
Hereditary haemorrhagic Telangiectasia
Granulomatosis with polyangitis
HTN
What are some examples of bleeding disorders that could lead to epistaxis?
Immune thrombocytopenia
Waldenstrom’s macroglobulinaemia
What is angiofibroma?
Often juvenile angiofibroma
benign tumor of blood vessels and fibrous tissues that is highly vascularised - often on nose and cheeks (small red bumps)
see in adolescent males
What is management of epistaxis? (BB lec think broad headings for now)
Initial assessment :
Acitively bleeding ?
Signs of shock (pale, pulse, BP)?
Cannulate (bloods for Hb, G&S, clotting)
Examine - identify location of bleed
Nasal cautery
Nasal packing (merocil, catheter, BIPP)
Surgery
If a pt with epistaxis is haemodynamically stable, first aid measures are all that is needed. Outline what these are…
- Sit pt forward with mouth open
(so they can spit out blood/ reduce risk of aspirating and decrease blood flow to nasopharynx) - Pinch the cartilaginous soft are of nose for at least 20 mins
(ask pt to breathe through mouth) - consider topical antiseptic to reduce risk of crusting / vestibulitis e.g. Mupirocin
Which pts with epistaxis should you have a low threshold for admission?
Comorbidity
e.g. coronary artery disease / severe HTN/ underlying cause is suspected
Children under 2 yrs
haemophilia / leukaemia (underlying) cause more likely
If bleeding from nose does not stop after 10-15 minites of continuous pressure what should you consider ?
Cautery initially if source of bleed is visible
Packing - if cautery not tolerated / cannot visualise bleed point
What might need to be done for pts who have not repsonded to all emergency management of epistaxis?
Sphenopalatine ligation in theatre
AR the management of epistaxis flow diagram
How would you classify epistaxis?
Anterior bleeds
Posterior bleeds
Where is an anterior bleed located in epsitaxis?
Originate from “Little’s” area a high vascularised region formed by anastomosis of 5 arteries
Which are more a common cause of epistaxis: anterior or posterior bleeds?
Anterior - Little’s area = 90% cases
Where is a posterior bleed located in espistaxis?
Posterior nasal cavity, often from branches of sphenopalatine arteries of nose
more common in older pts
Complication of nasal cautery?
Septal perforation
