What is the appropriate management of epistaxis, including initial compression, use of topical vasoconstrictors, chemical cautery, nasal packing, and follow‑up care?

Management of Epistaxis

Begin immediate management with firm, sustained compression of the lower third of the nose for at least 5 minutes, followed by topical vasoconstrictors (oxymetazoline or epinephrine), then chemical or electrical cautery if a bleeding site is identified, and finally nasal packing if these measures fail—with nonresorbable packing removed within 5 days to prevent complications. 1, 2

Initial Assessment and Triage

Distinguish patients requiring prompt management from those who do not at first contact. Patients needing immediate intervention include those with:

• Active bleeding with hemodynamic instability
• Airway compromise
• Inability to control bleeding with simple measures
• Significant comorbidities (anticoagulation, bleeding disorders, liver/kidney disease) 1, 2

Document critical risk factors immediately: personal or family history of bleeding disorders, anticoagulant/antiplatelet medications, intranasal drug use, prior nasal surgery, nasal trauma, CPAP/oxygen cannula use 1

Stepwise Treatment Algorithm

Step 1: Nasal Compression (First-Line)

• Apply firm, sustained pressure to the lower third of the nose for 5 minutes or longer
• Patient or caregiver can assist with compression
• This is the simplest, most effective initial intervention 1, 2

Step 2: Topical Vasoconstrictors

If compression alone fails:

• Apply oxymetazoline or phenylephrine spray (over-the-counter options)
• Alternative: epinephrine 1:1,000 or cocaine on cotton pledgets
• Studies show 65-75% resolution with oxymetazoline alone 1
• Caution: May increase cardiac complications in susceptible patients 1

Step 3: Identify Bleeding Source

• Use nasal speculum and headlamp for visualization
• Nasal endoscopy localizes bleeding in 87-93% of cases 1
• Most anterior bleeds originate from Kiesselbach's plexus
• Posterior bleeds (10% of cases) arise from sphenopalatine artery branches

Step 4: Cautery (If Source Identified)

When a specific bleeding site is visualized:

• Chemical cautery (silver nitrate) or electrical cautery under local anesthesia
• More effective than chemical with fewer recurrences (14.5% vs 35.1%) 1
• Critical pitfall: Avoid bilateral simultaneous septal cautery to prevent septal perforation 1
• Apply moisturizing agents after cautery to prevent recurrence 1

Step 5: Nasal Packing (If Above Measures Fail)

Packing options:

• Resorbable materials (Nasopore, gelatin sponge, thrombin matrix): No removal needed, dissolve with saline sprays
• Nonresorbable materials (petroleum jelly gauze, PVA tampons/Merocel, Rapid-Rhino balloons): Require removal within 5 days 1

Emerging alternative: Topical tranexamic acid (TXA)

• 500 mg in 5 mL applied to pledget for 10-15 minutes
• Shows superior hemostasis (78% vs 35% with oxymetazoline, 31% with packing) 3, 4
• Reduces rebleeding and emergency department stays
• Particularly effective in anticoagulated patients 3
• Contraindicated in active thromboembolic disease

Packing Management and Complications

Duration: Nonresorbable packing must be removed within 5 days maximum to prevent complications 1

Antibiotic prophylaxis: Not mandatory for all patients. Evaluate individual infection risk, though evidence is insufficient to show benefit for preventing rare complications like toxic shock syndrome 1

Patient instructions with packing in place:

• Keep nose moist with saline sprays throughout the day
• Avoid straining, lifting >10 pounds, bending over, exercising
• Sleep with head elevated
• Use acetaminophen for pain—avoid aspirin and ibuprofen 1
• Do not blow nose; sneeze with mouth open 1

Warning signs requiring immediate reassessment:

• Return of bleeding from nose or mouth
• Fever >101°F
• Vision changes
• Shortness of breath
• Loss of color around nose
• Facial swelling or diffuse rash 1

Packing complications:

• Infection (sinusitis, rarely toxic shock syndrome)
• Septal perforation
• Nasal adhesions/scar bands
• Pressure necrosis
• Temporary worsening of sleep apnea 1

Follow-Up Care

With nonresorbable packing: Mandatory follow-up for removal within 5 days 1

With resorbable packing: Follow-up encouraged to monitor mucosal healing 1

After packing removal:

• Expect small amount of bleeding from raw surfaces
• Continue saline spray and moisturizing agents to prevent crusting
• If rebleeding occurs: apply nasal compression, consider vasoconstrictor spray
• Persistent bleeding warrants return to emergency department 1

Refractory Cases

If packing and cautery fail: Evaluate for surgical arterial ligation (sphenopalatine artery) or endovascular embolization 2

• Endoscopic SPA ligation more effective than conventional packing (97% vs 62%) 5
• Embolization has 80% success rate, reserved for surgical failures or specific high-risk cases 5, 6

Blood Pressure Management

Do not routinely lower blood pressure acutely in epistaxis patients—rapid reduction risks end-organ ischemia (renal, cerebral, coronary). Monitor blood pressure but base treatment decisions on bleeding severity and control difficulty, not hypertension alone 1
