Evidence‑Based Management of Epistaxis

Initial First‑Aid Measures

• The American Heart Association recommends that patients sit upright with the head tilted slightly forward and apply firm, continuous pressure to the lower third (soft portion) of the nose for 10–15 minutes without releasing pressure to allow clot formation. 1
• Breathing should be performed through the mouth while the patient spits out any blood rather than swallowing it, to reduce the risk of airway compromise and gastrointestinal irritation. 1
• Nasal pressure alone is sufficient to control bleeding in approximately 80 % of cases, including about 20 % of emergency‑department presentations. 1

When to Seek Immediate Medical Attention

• Emergency care is indicated if bleeding does not stop after 15 minutes of continuous manual pressure, if the patient becomes light‑headed from blood loss, or if the epistaxis is associated with trauma that includes signs of brain injury, obvious nasal deformity, or facial fracture. [1][2]
• Patients taking anticoagulant or antiplatelet agents, or those with known bleeding disorders, should be evaluated medically unless the bleeding has completely ceased. [1][3]

Clinical Assessment for Healthcare Providers

• The American Academy of Otolaryngology–Head and Neck Surgery advises performing an anterior rhinoscopy after removing any clots to locate the bleeding source. [3][4]
• Prompt management is required for patients with airway compromise (blood entering the oropharynx) or hemodynamic instability from blood loss. 5
• Document risk factors that increase the frequency or severity of epistaxis, such as use of anticoagulant/antiplatelet medication, hypertension, and underlying bleeding disorders. [3][4]

Treatment Algorithm

Anterior Bleeding Sites

• Nasal cautery with local anesthesia should be applied only to the active or suspected bleeding site to minimize tissue injury. 3
• Moisturizing or lubricating agents may be used as a preventive measure after hemostasis is achieved. 4

Ongoing Bleeding Despite Compression

• When the bleeding source cannot be identified, nasal packing should be applied. 3
• For patients with suspected bleeding disorders or those on anticoagulant/antiplatelet therapy, resorbable packing is preferred. [3][4]
• Patients receiving packing must be educated about the type of packing placed, the expected removal schedule (if non‑resorbable), post‑procedure care, and warning signs that require reassessment. [3][4]

Refractory or Recurrent Epistaxis

• Nasal endoscopy is recommended to locate the bleeding site and guide further management in patients with recurrent bleeding despite prior packing or cautery. 5
• If bleeding persists despite packing and cautery, evaluation for surgical arterial ligation (e.g., endoscopic sphenopalatine artery ligation) or endovascular embolization should be undertaken. 5

Special Considerations for Anticoagulated Patients

• In the absence of life‑threatening hemorrhage, first‑line local measures (compression, packing, cautery) should be initiated before reversal of anticoagulation, transfusion, or discontinuation of anticoagulant/antiplatelet agents, to preserve therapeutic anticoagulation and reduce thromboembolic risk. [3][4]5

Screening for Hereditary Hemorrhagic Telangiectasia (HHT)

• Patients with recurrent bilateral nosebleeds or a family history of similar episodes should be examined for nasal and oral mucosal telangiectasias. [3][4]

Documentation and Follow‑Up

• Outcomes of interventions (including non‑resorbable packing, surgery, or arterial ligation/embolization) should be documented within 30 days or a transition‑of‑care note should be recorded. [3][4]

Common Pitfalls to Avoid

• Cryotherapy (ice) is not supported by sufficient evidence as a primary treatment for epistaxis. [1][2]
• Tilting the head backward should be avoided because it directs blood toward the airway and stomach. 1
• Cautery must be limited to the active bleeding site; broad application increases the risk of tissue damage. [3][4]
• Immediate discontinuation of anticoagulation is discouraged; local hemostatic measures should be attempted first unless bleeding is life‑threatening. [3][5]

Patient Education

• Preventive measures include nasal humidification, avoiding nose picking, and refraining from vigorous nose blowing. 4
• Home treatment should emphasize the correct compression technique (upright position, forward head tilt, 10–15 minutes of firm pressure). 5
• Patients should be instructed to seek additional medical care if bleeding persists longer than 15 minutes, if they feel light‑headed, or if they experience recurrent episodes. 2

Evidence‑Based Management of Anterior Epistaxis

Initial Non‑Pharmacologic Management

• Position and pressure: The patient should sit upright with the head tilted slightly forward (not backward) and apply firm, continuous pressure to the soft (lower third) portion of the nose for 10–15 minutes without releasing pressure to allow clot formation. 6
• Breathing technique: While the pressure is maintained, the patient should breathe through the mouth and expectorate blood rather than swallow it. 6

Criteria for Immediate Emergency Referral

• Urgent evaluation is required when any of the following occur after 15 minutes of continuous manual pressure: persistent bleeding, light‑headedness from blood loss, associated facial or head trauma with signs of brain injury, nasal deformity or fracture, or ongoing bleeding in a patient taking anticoagulant or antiplatelet therapy. 6

Topical Vasoconstrictor Use

Oxymetazoline Application (American Academy of Otolaryngology–Head and Neck Surgery)

• Technique: After clearing clots by having the patient blow the nose, spray two sprays of oxymetazoline into the bleeding nostril, then continue holding the soft part of the nose for 5 minutes; the procedure may be repeated once if needed. 7

Epinephrine‑Related Contraindications (American Academy of Otolaryngology–Head and Neck Surgery)

• Drug‑interaction warning: Patients receiving monoamine‑oxidase inhibitors or tricyclic antidepressants have a relative contraindication to topical epinephrine because of potential adverse drug interactions. 7

Documentation Requirements (American Academy of Otolaryngology–Head and Neck Surgery)

• Outcome recording: For patients treated with non‑resorbable packing, surgical intervention, arterial ligation, or embolization, document the intervention outcome within 30 days or record a transition‑of‑care note; include the type of packing used, expected removal schedule, and patient education provided. 7

Unsupported Adjunctive Measures

• Cryotherapy: The use of ice or other cryotherapy techniques lacks supporting evidence and is not recommended as a primary treatment for anterior epistaxis. 6
