How should I manage an acute epistaxis?

Management of Acute Epistaxis

Seat the patient upright with head tilted slightly forward and apply firm, continuous pressure to the soft lower third of the nose for a full 10–15 minutes without checking for cessation—this single maneuver resolves the vast majority of anterior nosebleeds and is the most critical intervention. 1

Immediate First-Line Treatment

Positioning and Compression

• Position the patient seated with head tilted slightly forward to prevent blood from flowing into the airway or stomach 1, 2
• Instruct the patient to breathe through the mouth and expectorate blood rather than swallowing it 1, 2
• Apply firm, continuous pressure to the soft lower third of the nose for 10–15 minutes without intermittent checking; premature release is the most common cause of treatment failure 1, 2
• Compression alone resolves the majority of anterior epistaxis cases 1

Adjunctive Vasoconstrictor Therapy

• If bleeding persists after 15 minutes of proper compression, clear the nasal cavity of clots and apply a topical vasoconstrictor (oxymetazoline or phenylephrine—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 1, 3
• Obtain baseline blood pressure before using vasoconstrictors because approximately one-third of epistaxis patients have undiagnosed hypertension, and vasoconstrictors carry increased risk of cardiac or systemic complications in this population 1

When Basic Measures Fail: Nasal Packing

Indications for Nasal Packing

Proceed to nasal packing only when: 1

• Bleeding persists after 15–30 minutes of continuous compression combined with topical vasoconstrictors
• Life-threatening hemorrhage is present
• A posterior bleeding source is suspected

Selection of Packing Material

• For patients on anticoagulants or antiplatelet medications, use only resorbable/absorbable packing materials (Nasopore, Surgicel, Floseal) to minimize trauma during removal 1, 2, 4
• For patients without bleeding risk factors, either resorbable or non-resorbable materials may be used 1
• Apply saline nasal spray frequently throughout the day to keep packing moist 1

Critical Anticoagulation Management Principles

Do not discontinue anticoagulation, reverse it, or administer blood products for non-life-threatening epistaxis—always attempt first-line local control measures (compression, vasoconstrictors, cautery, packing) before considering any anticoagulation reversal. 1, 2

Life-Threatening Bleeding Reversal (Only)

For massive hemorrhage with hemodynamic instability: 1

• Warfarin: 4-factor prothrombin complex concentrate (PCC) provides faster INR correction than fresh frozen plasma
• Direct oral anticoagulants (apixaban, rivaroxaban, dabigatran, edoxaban): 4-factor PCC; idarucizumab specifically for dabigatran
• Aspirin/clopidogrel: Platelet transfusion (effectiveness depends on timing of last dose)

Prevention of Recurrence

Once bleeding stops, apply petroleum jelly or lubricating agents to the nasal mucosa 2–3 times daily to maintain moisture and prevent recurrence 1, 2, 4

Additional preventive measures: 1, 2, 4

• Use saline nasal sprays regularly throughout the day to keep nasal mucosa moist
• Recommend a humidifier in dry environments
• Avoid digital trauma (nose picking) and vigorous nose blowing for at least 7–10 days

Advanced Interventions for Refractory Cases

Diagnostic Endoscopy

• Perform anterior rhinoscopy after clot removal to identify the bleeding source 1
• If the source remains unclear or bleeding is difficult to control, proceed to nasal endoscopy, which localizes the bleeding site in 87–93% of cases 1, 3

Cauterization

• Anesthetize the identified bleeding site with topical lidocaine before cautery 1
• Cauterize only the active bleeding point 1
• Avoid bilateral simultaneous septal cautery because it markedly increases the risk of septal perforation 1
• Electrocautery is more effective with fewer recurrences (14.5%) compared to chemical cauterization (35.1%) 3

Surgical/Interventional Options

For persistent or recurrent bleeding not controlled by packing or cautery, evaluate for: 1

• Endoscopic sphenopalatine artery ligation: 97% success rate versus 62% for conventional packing 1, 3
• Endovascular embolization: 80% success rate with recurrence rates <10% compared to 50% for nasal packing 1, 3

Red-Flag Signs Requiring Immediate Escalation

Seek immediate medical attention if: 1, 2, 4

• Bleeding persists after 15 minutes of continuous proper compression
• Bleeding duration exceeds 30 minutes over a 24-hour period
• Hemodynamic instability (tachycardia, hypotension, dizziness, lightheadedness)
• Active bleeding despite correctly placed nasal packing
• Fever >38.3°C (101°F)
• New visual disturbances
• Airway compromise from blood in the oropharynx

Common Pitfalls to Avoid

• Insufficient compression time: Must maintain pressure for full 10–15 minutes without checking 1, 2
• Tilting head backward: Causes blood to flow into throat and stomach, potentially causing vomiting, and does not help control bleeding 2
• Premature anticoagulation reversal: Dramatically increases stroke risk and should only occur in life-threatening scenarios 2
• Using non-resorbable packing in anticoagulated patients: Increases trauma risk during removal 1, 2
• Bilateral simultaneous septal cautery: Markedly increases septal perforation risk 1

Special Populations

Elderly Patients

• Age ≥75 years requires urgent triage because age-related anatomic changes increase likelihood of posterior sources and complications 1

Hereditary Hemorrhagic Telangiectasia (HHT)

• Screen for HHT in patients with recurrent bilateral nosebleeds or family history by examining for nasal and oral mucosal telangiectasias 1
• Refer HHT patients to specialized centers for comprehensive management 1
