## Management of Epistaxis: Stepwise Approach ### Initial Assessment & Conservative Management 1. **Positioning:** Sit upright, lean forward (prevent blood aspiration) 2. **Pressure:** Direct digital pressure on nostrils for 10–15 minutes 3. **Topical measures:** Saline irrigation, epinephrine-soaked gauze, silver nitrate cautery 4. **Cautery:** Silver nitrate or electrocautery for visible bleeding vessel (anterior epistaxis) ### Why Option B is INCORRECT **High-Yield:** Hydrogen peroxide is **NOT** an appropriate agent for anterior nasal packing in epistaxis. Hydrogen peroxide is a mucosal irritant that can cause tissue damage, oxidative injury to the nasal mucosa, and paradoxically worsen bleeding. It has no vasoconstrictive properties and is not recommended in standard ENT practice for nasal packing. The correct agents for ribbon gauze packing include: - **Epinephrine (adrenaline):** Vasoconstrictor — appropriate and widely used - **BIPP (Bismuth Iodoform Paraffin Paste):** Antiseptic, commonly used for ribbon gauze packing - **Merocel sponge:** Expands on contact with blood/saline - **Lidocaine with epinephrine:** Combined anesthetic and vasoconstrictor Hydrogen peroxide may be used for wound cleaning in other contexts but is **contraindicated** for nasal packing due to mucosal toxicity. (Scott-Brown's Otorhinolaryngology, 8th ed.; Cummings Otolaryngology, 7th ed.) ### Anticoagulation Management in Epistaxis **Key Point:** In a patient on warfarin with severe posterior epistaxis and INR >4: - Reversal of anticoagulation is appropriate when bleeding is severe and life-threatening - **Vitamin K** (5–10 mg IV/PO) is appropriate for supratherapeutic INR - **Prothrombin Complex Concentrate (PCC)** is preferred over FFP for rapid reversal - **FFP** may be used when PCC is unavailable, but is not first-line - The decision to reverse must balance bleeding severity against stroke risk in AF Option A, while imperfect in combining FFP and vitamin K, describes a clinically defensible approach for severe posterior epistaxis with INR >4 — reversal of anticoagulation in this context is appropriate, even if PCC is preferred over FFP. ### Anterior vs. Posterior Epistaxis Management | Step | Anterior Epistaxis | Posterior Epistaxis | |------|-------------------|--------------------| | 1st line | Digital pressure, topical agents, cautery | Digital pressure, topical agents | | 2nd line | Anterior nasal packing (ribbon gauze with BIPP/epinephrine, Merocel) | Anterior packing | | 3rd line | — | Posterior packing or balloon (Foley, Bellocq's) | | Definitive | Sphenopalatine artery ligation/embolization | Sphenopalatine artery ligation/embolization | ### Posterior Packing Techniques (Option C — Correct) - **Bellocq's pack:** Gauze secured with ties through the mouth — standard technique - **Foley catheter (14–16 Fr):** Balloon inflated with 10–15 mL saline, pulled anteriorly to tamponade — widely used - **Purpose-designed epistaxis balloons:** Rapid Rhino, Merocel posterior pack ### Definitive Interventions (Option D — Correct) **Endoscopic Sphenopalatine Artery Ligation (ESPAL):** - Success rate >90%, minimally invasive - Indicated for recurrent or refractory posterior epistaxis - Preferred over open ligation **Angiographic Embolization:** - Reserved for surgical failures or contraindications to surgery **Clinical Pearl:** The key teaching point is that hydrogen peroxide has NO role in nasal packing for epistaxis — epinephrine (vasoconstrictor) is appropriate, but hydrogen peroxide is a mucosal irritant and is contraindicated.
