ENT \ Nose Bleeds Flashcards
What is the most common cause of nosebleeds (epistaxis)?
Local trauma caused by nose picking or direct blunt trauma
What are some other causes of epistaxis?
- Other trauma (surgery, forceful blowing)
- Chronic irritation (dry air, smoke/pollutants)
- Cocaine use
- Intranasal medications
- Nasal foreign body
- Intranasal polyp or tumor
- Systemic problems: bleeding diathesis, blood thinning medications, hypertension
What accompanying symptoms would prompt an evaluation for bleeding disorders?
- Frequent bleeding or bleeding from multiple sites other than just the nose
- excessive bleeding/bruising from minor wounds
- bleeding gums
- hematemesis
- melena
- menorrhagia
- history of postpartum bleeding
- history of excessive bleeding during surgery, etc)
What labs would you obtain to start this evaluation?
- Complete blood count
- prothrombin time (PT) and international normalized ratio (INR)
- partial thromboplastin time (PTT)
- peripheral blood smear
What is Kiesselbach plexus?
- An area in the anteroinferior part of the nasal septum where several arteries anastomose and is the most frequent area of epistaxis
What is the management of a stable patient with a nosebleed?
- Patient should lean forward (avoids posterior blood accumulation)
- blow out clots
- then squeeze cartilaginous nose (steady moderate pressure for 5-20 minutes)
- while you perform history and physical (look for easily reversible cause of bleeding).
If initial first aid(lean forwars and apply pressure) does not stop a nose bleed and you confirm an anterior nosebleed with direct visualization, what other steps can you take to stop the bleeding?
- Intranasal oxymetazoline (decongestant) and
- lidocaine (analgesic) phenylephrine
- Cautery with silver nitrate or
- nasal packing
If a patient is (nose)bleeding profusely and the nose bleeding is difficult to stop, what kind of bleed (in terms of location) are you most likely dealing with?
Posterior bleed (although anterior bleed is still possible)
What management steps should you take for a profusely bleeding nose?
- this is more likely a posterior bleed
- Use universal precautions (eye mask, gown)
- Start large bore IV
- FBC, type and cross
- epistaxis tray
- Tamponade bleed:
- nasal catheter with dual-chambered cuff
- foley cathete
- or posterior packing
- Consider ENT referral
What are the most worrisome complications from severe acute nosebleeds?
Airway compromise and hemodynamic instability
