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 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 assoc with:
    • Coagulopathy
    • Significant hemorrhage visible in posterior nasopharynx
    • 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 to nose
   1. Pt leans forward w/ nares pinched between thumb and middle finger for 10-15min

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 achieve bloodless field, place silver nitrate just proximal to bleeding source
   1. Leave on for only a few siconds

Thrombogenic Foams

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

Anterior Nasal Packing

1. Only use if all of the above have failed
2. Rapid Rhino
   1. Soak balloon w/ water and insert along the floor of the nasal cavity
   2. Inflate slowly with air until the bleeding stops
3. 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. Traditional Packing
   1. Apply ribbon gauze in accordion-like manner

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

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. Precribe amoxicillin-clavulanate if anterior packing was placed
   5. ENT or ED follow-up in 2-3d for removal of nonbiodegradable packing
2. Posterior Epistaxis
   1. Admission is strongly advised
