Topical vasoconstrictors
Oxymetazoline 0.05 percent intranasal
2 sprays to affected nostril then compression
Repeat once after 10 minutes if persistent bleeding
Phenylephrine 0.25 to 1 percent intranasal
1 to 2 sprays then compression
Avoid in severe uncontrolled hypertension when possible
Visualization and directed therapy
Anterior suction and illumination
Clot removal enabling source identification
Chemical cautery for visible anterior point
Silver nitrate applicator

Analgesia and anxiolysis
Intranasal lidocaine adjunct when feasible
Systemic analgesia for discomfort
Packing management
Reassessment after placement
Oropharynx check for continued posterior flow
Antibiotic considerations
Limited evidence for routine prophylaxis
Consider antibiotics for prolonged nonabsorbable packing and high risk sinusitis or immunocompromise
Removal timing plan
Typical anterior pack removal within 24 to 72 hours with follow up
Posterior epistaxis pathway
Posterior bleed recognition
Persistent bleeding with bilateral nares and posterior pharynx blood
Failure of anterior packing control
Higher severity typical pattern
Posterior packing techniques
Balloon catheter posterior pack
Double balloon devices commonly used
Admit with monitoring due to complication risk
Foley catheter posterior pack when appropriate expertise
Balloon seated in nasopharynx with anterior traction
Combined anterior pack for stabilization per technique descriptions
Posterior pack precautions
Continuous pulse oximetry
Hypoxia risk
Telemetry
Dysrhythmia risk
Airway readiness
Aspiration risk from continued bleeding or sedation
Definitive escalation therapies
Endoscopic management
Endoscopic cautery when bleeding point identified
Potential to avoid prolonged packing in selected posterior cases
Endoscopic sphenopalatine artery ligation
Common definitive surgical option for posterior epistaxis
Embolization
Interventional radiology embolization for refractory severe epistaxis
Guideline includes embolization among complex management options
Anticoagulation and antiplatelet associated bleeding
Medication related bleeding framework
Shared decision making with prescribing team when feasible
Thrombotic risk versus bleeding control
Warfarin reversal for life threatening bleeding
Four factor PCC dosing per institutional protocol
Concurrent vitamin K IV per institutional protocol
INR reassessment after PCC effect
Dabigatran reversal for life threatening bleeding
Idarucizumab per institutional protocol
Factor Xa inhibitor reversal for life threatening bleeding
Andexanet alfa when available per institutional protocol
Four factor PCC as alternative per institutional protocol
Antiplatelet effect mitigation
Platelet transfusion consideration only for life threatening bleeding and active antiplatelet effect with specialist input
Adjunct pharmacologic hemostasis
Tranexamic acid topical
Evidence mixed across trials
Faster cessation and reduced rebleeding reported in some RCTs
No benefit reported in large pragmatic ED trial summary
Practical topical approach
TXA 500 mg in 5 mL on pledget to bleeding nostril
Leave in place 10 to 15 minutes then reassess
Avoid if known hypersensitivity
Evidence levels and guideline alignment
Guideline supported first line steps
Compression and topical vasoconstrictors
Recommended as first line options in AAO-HNSF guideline
Nasal packing and cautery as escalation
Included in AAO-HNSF guideline management steps
Evidence grading placeholders for local mapping
ACEP Level B for topical TXA as adjunct
Evidence heterogeneity and local protocol dependent
Class IIa recommendation for posterior epistaxis definitive control with endoscopic arterial ligation when available
Guideline includes ligation among complex options
Special Populations
Pregnancy
Pregnancy considerations
Increased nasal mucosal vascularity and congestion
Higher baseline epistaxis propensity
Medication safety
Prefer topical local therapies over systemic agents when possible
Avoid excessive systemic vasoconstrictor exposure
Severe bleeding escalation
Obstetric consultation when hemodynamic instability or significant anemia
Geriatric
Older adult considerations
Higher anticoagulant and antiplatelet prevalence
Lower threshold for labs and observation
Posterior bleeds more common relative to younger patients in practice patterns
Lower threshold for ENT involvement
Pack related complications
Hypoxia and delirium risk with sedation and obstruction
Pediatrics
Pediatric considerations
Most episodes anterior and benign
Digital trauma and mucosal dryness common
Foreign body suspicion
Unilateral malodor and discharge
Bleeding disorder screening
Recurrent severe episodes
Family history
Sedation caution
Airway protection priority in active bleeding
Background
Epidemiology
Epidemiologic facts
Common lifetime occurrence
Most patients managed conservatively
Anterior predominance
Approximately 90 percent anterior reported in clinical summaries
Posterior epistaxis less common and more severe
More likely to require packing and admission
Pathophysiology
Bleeding anatomy
Kiesselbach plexus anterior septum source
Common anterior site accessible to cautery
Sphenopalatine artery branches posterior source
Higher flow and more difficult visualization
Mucosal dryness and inflammation
Barrier disruption and friability
Therapeutic Considerations
Treatment principles
Stepwise escalation
Compression and vasoconstrictor
Visualization and cautery
Packing
Definitive ligation or embolization for refractory cases
Posterior packing risk profile
Hypoxia and dysrhythmias and pressure necrosis concerns
Topical TXA uncertainty
Conflicting RCT outcomes
Patient Discharge Instructions
Copy discharge instructions
Discharge instructions
If bleeding restarts, pinch soft part of nose continuously for 10 to 15 minutes while leaning forward
If not controlled after two cycles, return to ED
Avoid nose blowing for 24 to 48 hours
Sneeze with mouth open
Avoid heavy lifting and strenuous exercise for 48 hours
Avoid hot showers and alcohol for 24 hours
Saline spray or gel several times daily for moisture
Humidifier at night if dry environment
Thin layer of petroleum based ointment to anterior septum nightly for 3 to 5 days if dryness
Avoid deep insertion
Return immediately for red flags
Bleeding that will not stop with pressure
Large clots or heavy continuous flow
Fainting or severe weakness
Shortness of breath or chest pain
Vomiting blood or black stools
If packing in place
Do not remove at home unless specifically instructed
Follow up for removal within 24 to 72 hours per plan
Return for fever, worsening pain, foul discharge, or recurrent bleeding
