What's the next step in managing epistaxis (nosebleed) with hypotension (low blood pressure) that's not controlled with tranexamic acid (TXA), haemocoagulase, and nasal packing?

Management of Refractory Epistaxis with Hypotension

For epistaxis with hypotension that has failed tranexamic acid, haemocoagulase, and nasal packing, proceed immediately to nasal endoscopy to identify the bleeding site, followed by either endoscopic arterial ligation (particularly sphenopalatine artery) or endovascular embolization. 1

Immediate Hemodynamic Stabilization

• Resuscitate the patient first - hypotension with ongoing epistaxis represents life-threatening bleeding requiring emergent hospital or emergency department evaluation 1
• Signs of acute hypovolemia (hypotension, tachycardia, syncope) warrant prompt aggressive management 1
• Establish IV access and initiate fluid resuscitation while simultaneously controlling bleeding 1
• Consider blood transfusion for severe blood loss, though first-line treatments should be attempted first unless bleeding is truly life-threatening 1, 2

Diagnostic Endoscopy

Perform nasal endoscopy immediately to examine the nasal cavity and nasopharynx, as this is specifically indicated when epistaxis is difficult to control 1

• Endoscopy allows identification of the bleeding site that could not be visualized with anterior rhinoscopy 1, 3
• This is critical for guiding the next intervention, whether surgical ligation or embolization 3
• Proper positioning, topical vasoconstricting anesthesia, and suctioning enhance visualization 4

Definitive Interventions for Refractory Bleeding

Endoscopic Arterial Ligation (Preferred Surgical Option)

• Endoscopic sphenopalatine artery (SPA) ligation is more effective than conventional nasal packing (97% vs 62% success rate) 5
• Endoscopic cauterization of identified vessels is even more effective than ligation alone 5
• This approach is appropriate for persistent or recurrent bleeding not controlled by packing 3

Endovascular Embolization (Alternative Definitive Treatment)

• Embolization using gelatin sponge, foam, PVA particles, or coils achieves approximately 80% success rate 5
• Efficacy and complication rates are comparable to surgical methods 5
• This is the definitive option when surgical ligation is not feasible or has failed 3

Critical Management Principles

Do not reverse anticoagulation or withdraw antiplatelet medications unless bleeding is truly life-threatening and cannot be controlled by other means 1, 2

• First-line and advanced treatments should be exhausted before considering anticoagulation reversal 1, 2
• If the patient is anticoagulated, consult with the team managing anticoagulation before making changes 6

Common Pitfalls to Avoid

• Delaying endoscopy: When standard measures fail, endoscopy should not be delayed as it is essential for identifying posterior or difficult-to-visualize bleeding sources 1
• Inadequate resuscitation: Hypotension must be addressed simultaneously with bleeding control 1
• Premature anticoagulation reversal: This should be a last resort after definitive interventions have been attempted 1, 2
• Repeated packing without escalation: If initial packing fails, proceeding to endoscopic evaluation and definitive treatment is more effective than repeated packing attempts 5

Documentation and Follow-up

• Document the outcome of intervention within 30 days or document transition of care for patients requiring surgery or arterial ligation/embolization 1, 3
• Patients requiring these advanced interventions need close follow-up given the severity of their initial presentation 1
