What is the recommended step‑by‑step treatment for acute epistaxis in an adult, including initial nasal pressure, topical vasoconstrictors, cautery, nasal packing, and management of patients on anticoagulant therapy?

Epistaxis Treatment: Step-by-Step Management

Initial First-Line Intervention: Nasal Compression

Apply firm, continuous pressure to the soft lower third of the nose for a full 10–15 minutes without checking if bleeding has stopped—premature release is the most common cause of treatment failure. 1, 2

• Position the patient seated upright with head tilted slightly forward to prevent blood from entering the airway or stomach 2
• Instruct the patient to breathe through the mouth and spit out blood rather than swallow it 1, 2
• Compression alone resolves the vast majority of anterior epistaxis cases 1
• While applying compression, obtain a medication history (anticoagulants, antiplatelets, NSAIDs), personal or family history of bleeding disorders, and measure baseline blood pressure (approximately 33% of epistaxis patients have undiagnosed hypertension) 1, 2

Second-Line: Topical Vasoconstrictors

If bleeding persists after 10–15 minutes of proper compression, apply topical vasoconstrictor spray (oxymetazoline or phenylephrine) with 2 sprays into the bleeding nostril, then resume firm compression for another 5–10 minutes. 1, 2

• Vasoconstrictor application stops bleeding in 65–75% of emergency department cases 2, 3
• Before using vasoconstrictors, verify blood pressure is stable, as these agents carry increased risk of cardiac or systemic complications in hypertensive or cardiovascular-compromised patients 2
• Clear blood clots from the nasal cavity by gentle nose blowing or suction before applying the vasoconstrictor to improve contact with bleeding mucosa 2, 4

Third-Line: Cautery (When Bleeding Site is Identified)

If a focal bleeding point is visible on anterior rhinoscopy after clot removal, anesthetize the site with topical lidocaine and cauterize only the active bleeding point. 2, 4

• Electrocautery is more effective than chemical cauterization with silver nitrate, showing fewer recurrences (14.5% vs 35.1%) 2, 3
• Never perform bilateral simultaneous septal cautery—this markedly increases the risk of septal perforation 1, 2
• If anterior rhinoscopy fails to identify the source, proceed to nasal endoscopy, which localizes the bleeding site in 87–93% of cases 2, 4

Fourth-Line: Nasal Packing

Proceed to nasal packing only when bleeding persists after 15–30 minutes of proper compression combined with vasoconstrictors, when bleeding is life-threatening, or when a posterior bleeding source is suspected. 1, 2

Selection of Packing Material Based on Anticoagulation Status:

For patients on anticoagulants or antiplatelet medications (excluding low-dose aspirin alone), use only resorbable/absorbable packing materials (Nasopore, Surgicel, Floseal) to reduce trauma during removal. 1, 2

• Resorbable packing reduces the likelihood of additional bleeding when material is removed and improves patient comfort compared to non-resorbable packing 1
• For patients not on antithrombotic therapy, either resorbable or non-resorbable materials may be used 2
• After packing placement, instruct the patient to apply saline nasal spray frequently throughout the day to keep packing moist 2
• Educate the patient about the type of packing used, timing for removal (if non-resorbable), and warning signs requiring immediate reassessment (active bleeding despite packing, fever >101°F, vision changes, shortness of breath, facial swelling) 2

Management of Patients on Anticoagulant/Antiplatelet Therapy

Do not discontinue anticoagulant or antiplatelet agents before attempting first-line local measures (compression, vasoconstrictors, cautery, packing) unless bleeding is life-threatening with hemodynamic instability or airway compromise. 2

Specific Anticoagulation Guidance:

• Aspirin for cardiovascular protection should be continued despite epistaxis—the survival benefits outweigh bleeding risks in high-risk patients with recent MI or stents 2
• For patients on warfarin who are hemodynamically stable with controlled bleeding after local measures, do not reverse anticoagulation 2
• Life-threatening epistaxis reversal protocols (only when massive hemorrhage, hemodynamic instability, or airway compromise exists): 2
  • Warfarin: 4-factor prothrombin complex concentrate (PCC) provides faster INR correction than fresh frozen plasma
  • Apixaban/rivaroxaban/edoxaban: 4-factor PCC (2,000 units) or andexanet alfa
  • Dabigatran: idarucizumab (specific reversal agent) or 4-factor PCC
  • Unfractionated heparin/LMWH: protamine sulfate

Advanced Interventions for Refractory Bleeding

For persistent or recurrent bleeding not controlled by packing or cautery, evaluate candidacy for surgical arterial ligation or endovascular embolization. 2, 3

• Endoscopic sphenopalatine artery ligation has a 97% success rate compared to 62% for conventional packing 2, 3
• Endovascular embolization has an 80% success rate with recurrence rates <10% compared to 50% for nasal packing 2, 3
• Refer to otolaryngology when bleeding persists despite appropriate nasal packing, when recurrent epistaxis occurs despite correct local treatment, or after three failed packing attempts 2, 4

Prevention of Recurrence

After hemostasis is achieved, apply petroleum jelly or nasal saline gel to the anterior nasal septum 2–3 times daily to maintain moisture and prevent recurrence. 2, 4

• Use saline nasal sprays frequently throughout the day to keep nasal mucosa moist 2, 4
• Recommend a bedside humidifier in dry environments, as dry heat creates fragile, hyperemic nasal mucosa that bleeds easily 2, 5
• Instruct patients to avoid nose picking, vigorous nose blowing, and nasal decongestants for at least 7–10 days after treatment 2

Critical Pitfalls to Avoid

• Do not check if bleeding has stopped before completing the full 10–15 minutes of compression—this is the single most common error leading to treatment failure 2, 6
• Do not use non-resorbable packing in patients on anticoagulants or antiplatelets—removal causes significant mucosal trauma and rebleeding 1, 2
• Do not overlook hereditary hemorrhagic telangiectasia (HHT) in patients with recurrent bilateral nosebleeds or family history—inspect nasal and oral mucosa for telangiectasias 2, 4
• Do not apply ice packs as a first-aid intervention—current evidence does not support this practice, as it does not significantly change nasal blood flow 2

When to Escalate Care Immediately

Return to the emergency department or seek immediate evaluation if: 2

• Active bleeding persists after 15 minutes of continuous proper compression
• Bleeding duration exceeds 30 minutes over a 24-hour period
• Signs of hemodynamic instability (tachycardia, hypotension, dizziness, weakness)
• Active bleeding from nose or mouth despite correctly placed packing
• Fever >101°F with packing in place
• New visual disturbances or facial swelling
