Epistaxis

Background

1. Types
   1. Anterior
      1. 90% of nosebleeds
      2. Occur in anterior septum (Kiesselbach plexus)
      3. Can visualize with anterior rhinoscopy
   2. Posterior
      1. 10% of nosebleeds
      2. Occur from nasopalatine branch of sphenopalatine artery
      3. Cannot visualize
2. Risk factors
   1. Digital trauma
   2. Rhinosinusitis
   3. Anticoagulant/antiplatelet use
   4. Trauma
   5. Neoplasia
   6. Hypertension (does not cause bleeding but prolongs existing bleeding)

Diagnosis

• Anterior versus posterior hemorrhage
  • Assume posterior if measures to control anterior bleeding fail
  • Posterior bleeding associated with:
    • Coagulopathy
    • Significant hemorrhage visible in posterior nasopharynx
    • Sensation of blood dripping down throat
    • Hemorrhage from bilateral nares
    • Epistaxis uncontrolled w/ either anterior rhinoscopy or anterior pack

Treatment

Direct Nasal Pressure

1. Have pt blow nose to expel clots or suction nose
2. Instill topical vasoconstrictor (oxymetazoline or phenylephrine)
3. Have pt apply direct pressure over cartilaginous area of nasal bridge (not the bony area)
4. Pt may lean forward to avoid aspiration of blood

Chemical Cauterization

1. Consider if two attempts at direct pressure fail
2. Only perform if the bleeding vessel is adequately visualized
3. Anesthetize w/ cotton pledgets soaked in 1:1 mix of 0.05% oxymetazoline:4% lidocaine
4. Once bloodless field obtained, place silver nitrate just proximal to bleeding source
   1. Leave on for a few seconds at most
   2. Never cauterize both sides of the septum at one go (risk of septal perforation)

Thrombogenic Foams

1. Apply Gelfoam or Surgicel on visualized bleeding mucosa
2. Bioabsorbable so removal/abx not needed

Anterior Nasal Packing

• Only use if all of the above have failed

1. Rapid Rhino
   1. Soak balloon w/ water(NOT saline) and insert along the floor of the nasal cavity
   2. Inflate slowly with air(NOT saline or water) until the bleeding stops
2. Merocel
   1. Absorbent nasal tampon
   2. Coat tampon w/ water-soluble abx ointment and insert along floor of nasal cavity
   3. If tampon has not expanded w/in 30s of placement, irrigate it in place w/ NS
   4. Moisten three times per day with saline or water until removal
3. Traditional Packing
   1. Apply ribbon gauze in accordion-like manner

Tranexamic acid

1. 500mg TXA applied to topical foam or non absorbable packing and inserted into nares.
2. Can stop bleeding as fast as 10 minutes

Posterior Nasal Packing

1. Only consider if all of the above have failed
2. Associated w/ higher complication rates (pressure necrosis, infection, hypoxia)
   1. Temporizing measure while awaiting ENT support
3. Consider nasal block as posterior packing is often very uncomfortable
4. All posterior packing should be accompanied by anterior packing
5. Rapid Rhino
   1. Inflate posterior balloon
6. Foley catheter w/ 30-cc balloon
   1. Lubricate w/ topical antibiotic
   2. Advance transnasally until visualized in posterior oropharynx
   3. Inflate balloon w/ 7cc of saline; retract 2-3cm until lodged in post nasopharynx
   4. Inflate w/ additional 5-7cc of saline to complete the pack
7. Keep packing for 72-96 hours, <48 hours associated with increased re-bleed.

Complications

• Recurrent unilateral epistaxis has been described in association with malignancy
• Toxic Shock Syndrome

Disposition

1. Anterior Epistaxis
   1. Discharge after 1hr of observation
   2. Pts w/ therapeutic warfarin levels may continue medication
   3. Discontinue NSAIDs for 3-4d
   4. Possible amoxicillin-clavulanate if anterior packing was placed as prophylaxis for bacterial sinus infection or TSS, though not standard of care.
   5. ENT or ED follow-up in 2-3d for removal of nonbiodegradable packing
2. Posterior Epistaxis
   1. Admission is strongly advised
