A 68-year-old man with hypertension (BP 160/95 mmHg) presents to the emergency department with active anterior epistaxis for 45 minutes. He has tried pinching the nose for 10 minutes without relief. On examination, bleeding is from the anteroinferior part of the nasal septum. Vital signs are stable. What is the most appropriate immediate next step in management?

Explanation

## Clinical Approach to Anterior Epistaxis **Key Point:** Anterior epistaxis (80–90% of cases) from Kiesselbach's plexus on the anteroinferior nasal septum is managed conservatively with topical vasoconstrictors and local measures before escalating to packing or cautery. ### Management Algorithm for Epistaxis ```mermaid flowchart TD A[Epistaxis presentation]:::outcome --> B{Anterior or posterior?}:::decision B -->|Anterior| C[Pinch nose 10-15 min<br/>+ head forward]:::action C --> D{Bleeding stopped?}:::decision D -->|Yes| E[Observe, discharge<br/>with precautions]:::outcome D -->|No| F[Apply topical 4% lidocaine<br/>+ 1:10,000 epinephrine]:::action F --> G[Anterior nasal packing<br/>Merocel or ribbon gauze]:::action G --> H{Rebleeding after 48-72 hrs?}:::decision H -->|Yes| I[Cautery or embolization]:::action H -->|No| J[Remove pack, discharge]:::outcome B -->|Posterior| K[Posterior packing or<br/>Foley catheter balloon]:::action K --> L[Admit, monitor,<br/>consider angiography]:::action ``` ### Why Topical Vasoconstrictor + Packing? **High-Yield:** The combination of: 1. **Topical lidocaine 4%** — local anesthetic (prevents pain, allows patient cooperation) 2. **Epinephrine 1:10,000** — α-adrenergic vasoconstriction (reduces bleeding) 3. **Anterior packing (Merocel or ribbon gauze)** — mechanical tamponade of the bleeding site This sequence controls >90% of anterior epistaxis without need for hospitalization or invasive procedures. **Clinical Pearl:** Merocel (expandable polyvinyl acetate sponge) is superior to plain gauze because it: - Expands on contact with blood to conform to the nasal cavity - Absorbs blood and promotes clotting - Can be left in place for 48–72 hours - Requires less frequent inspection than ribbon gauze ### Why NOT the Other Options? | Option | Why Incorrect | |--------|---------------| | **Neurosurgery referral for angiography** | Reserved for recurrent/refractory posterior epistaxis or suspected vascular malformations; not first-line for simple anterior bleeding in a stable patient | | **IV tranexamic acid alone** | Useful as adjunct in severe/recurrent cases, but does not address the immediate bleeding source; observation without local measures is inadequate | | **Rigid endoscopy under GA** | Appropriate for posterior epistaxis or when anterior packing fails; premature and unnecessary for initial anterior epistaxis management | **Warning:** Do NOT skip topical vasoconstriction—pinching alone has failed; escalate to pharmacologic + mechanical tamponade immediately. ### Post-Packing Management - Admit for observation if packing placed - Broad-spectrum antibiotics (e.g., amoxicillin-clavulanate) to prevent sinusitis - Analgesia and sedation as needed - Remove pack after 48–72 hours if no further bleeding - Cauterize bleeding vessel if rebleeding occurs after pack removal [cite:Robbins & Cotran 10e Ch 16]
