Epistaxis Management
Immediate First-Line Intervention
Apply firm, continuous pressure to the soft lower third of the nose for a full 10–15 minutes without checking for cessation of bleeding—this single maneuver resolves the vast majority of anterior epistaxis cases and premature release is the most common cause of treatment failure. 1
Proper Positioning and Technique
- Seat the patient upright with the head tilted slightly forward to prevent blood from entering the airway or stomach. 1
- Instruct the patient to breathe through the mouth and expectorate blood rather than swallow it. 1
- The compression must be sustained for the full duration without intermittent checking, as interruption resets the clotting process. 1
Second-Line Pharmacologic Adjunct
If bleeding persists after 10–15 minutes of proper compression:
- Apply topical vasoconstrictor spray (oxymetazoline or phenylephrine) 2 sprays into the bleeding nostril, then resume firm compression for an additional 5–10 minutes. 1
- This combination stops bleeding in 65–75% of emergency department presentations. 1, 2
Critical Caveat
- Obtain a baseline blood pressure before using topical vasoconstrictors, because approximately one-third of epistaxis patients have undiagnosed hypertension and vasoconstrictors carry increased risk of cardiac or systemic complications in this subgroup. 1
- Avoid repeated or prolonged vasoconstrictor use, as this precipitates rhinitis medicamentosa and worsening nasal obstruction. 1
Third-Line Intervention: Cautery
When compression and vasoconstrictors fail and a focal bleeding point is identified:
- After clot removal by suction or gentle nose blowing, perform anterior rhinoscopy to visualize the bleeding source. 1
- Anesthetize the identified site with topical lidocaine, then cauterize only the active bleeding point. 1
- Electrocautery is superior to chemical cauterization (silver nitrate), with recurrence rates of 14.5% versus 35.1%, respectively. 1, 2
- Never perform bilateral simultaneous septal cautery, as this markedly increases the risk of septal perforation. 1
Fourth-Line Intervention: Nasal Packing
Proceed to nasal packing only when:
- Bleeding persists after 15–30 minutes of proper compression combined with vasoconstrictors. 1
- Life-threatening hemorrhage is present. 1
- A posterior bleeding source is suspected. 1
Packing Material Selection
- For patients on anticoagulants or antiplatelet agents, use only resorbable/absorbable materials (Nasopore, Surgicel, Floseal) to avoid trauma during removal. 1
- For patients not on antithrombotic therapy, either resorbable or non-resorbable materials may be used. 1
Post-Packing Care
- Apply saline nasal spray frequently throughout the day to keep packing moist. 1
- Educate patients about the type of packing placed, timing and plan for removal, and warning signs requiring immediate reassessment. 1
Management of Anticoagulated Patients
Do not discontinue anticoagulant or antiplatelet agents, nor administer reversal agents or blood products, before attempting first-line local measures (compression, vasoconstrictor, cautery, packing) unless bleeding is life-threatening. 1
Specific Guidance by Agent
- For aspirin in high-risk cardiovascular patients (recent MI, stents), continue aspirin despite epistaxis—the survival benefits outweigh bleeding risks. 1
- For NSAIDs, do not routinely discontinue for standard epistaxis; most cases resolve with local measures alone. 1
- For warfarin with life-threatening hemorrhage, use 4-factor prothrombin complex concentrate (PCC) for faster INR correction with smaller infusion volume compared to fresh frozen plasma. 1
- For direct oral anticoagulants (DOACs) with life-threatening hemorrhage, use 4-factor PCC; idarucizumab specifically for dabigatran. 1
Advanced Diagnostic Evaluation
When anterior rhinoscopy fails to identify the source or bleeding is difficult to control:
- Perform nasal endoscopy, which localizes the bleeding site in 87–93% of cases. 1, 2
- Endoscopy is particularly useful for posterior epistaxis, which can originate from the septum or lateral nasal wall. 1
Escalation to Definitive Intervention
For persistent or recurrent bleeding not controlled by packing or cautery:
- Evaluate candidacy for surgical arterial ligation (endoscopic sphenopalatine artery ligation) or endovascular embolization. 1
- Endoscopic sphenopalatine artery ligation has a 97% success rate versus 62% for conventional packing. 1, 2
- Endovascular embolization has an 80% success rate with recurrence rates <10% compared to 50% for nasal packing. 1, 2
Prevention of Recurrence
Once hemostasis is achieved:
- Apply petroleum jelly or nasal saline gel to the anterior nasal mucosa 2–3 times daily to maintain moisture. 1
- Use saline nasal sprays frequently throughout the day. 1
- Recommend a humidifier in dry environments, as dry heat creates fragile, hyperemic nasal mucosa prone to bleeding. 1, 3
- Avoid nasal manipulation, vigorous nose-blowing, and nasal decongestants for at least 7–10 days after packing removal. 1
Red-Flag Criteria for Immediate Escalation
Refer to otolaryngology or escalate care immediately if:
- Active bleeding persists despite correctly placed packing. 1
- Hemodynamic instability (tachycardia, hypotension, dizziness). 1
- Fever >38.3°C (101°F). 1
- New visual disturbances. 1
- Recurrent bilateral nosebleeds (screen for hereditary hemorrhagic telangiectasia). 1
Documentation Requirements
- Record duration of bleeding, response to compression, medication history (anticoagulants, antiplatelets, NSAIDs), personal or family history of bleeding disorders, and baseline blood pressure. 1
- Document outcomes within 30 days for patients treated with non-resorbable packing, surgical ligation, or embolization. 1
Common Pitfalls to Avoid
- Premature release of compression before the full 10–15 minutes—this is the single most common error leading to treatment failure. 1
- Discontinuing aspirin in high-risk cardiovascular patients without weighing thrombotic risk. 1
- Using non-resorbable packing in anticoagulated patients. 1
- Applying bilateral septal cautery simultaneously. 1
- Failing to obtain baseline blood pressure before vasoconstrictor use. 1
