A 72-year-old man presents to the emergency department with a severe nosebleed that has lasted for two hours. He denies any recent trauma, easy bruising, or bleeding from any other sites. He has a history of hypertension and valvular atrial fibrillation that are treated with lisinopril, metoprolol, and warfarin. Despite 20 minutes of continuous pressure and the application of oxymetazoline-soaked pledgets, brisk bleeding continues from the right naris. Blood is also seen dripping down the posterior oropharynx. A complete blood count is normal, and the international normalized ration (INR) is 2.7.
Which of the following is the most appropriate next step in the management of this patient?
The correct answer is:
B) Nasal packing posteriorly
This patient is experiencing refractory epistaxis. Because initial conservative measures including pressure and vasoconstrictors have failed, the next step is nasal packing. Given the blood seen in the posterior oropharynx, a posterior bleed (likely from the sphenopalatine artery/Woodruff plexus) should be suspected, which may require a posterior pack or a balloon catheter. Anterior packing is generally attempted first if the source is visible anteriorly.
Answer choice A: Immediate arterial ligation, is incorrect. Surgical intervention (e.g., sphenopalatine artery ligation) or embolization is reserved for cases that fail both anterior and posterior packing. It is not the immediate next step.
Answer choice C: Oral vitamin K and FFP, is incorrect. While this patient is on warfarin and may have a high INR, the priority is local control of the hemorrhage. Reversal of anticoagulation should be considered concurrently, but it will not provide the mechanical tamponade needed to stop brisk arterial bleeding.
Answer choice D: Silver nitrate cautery, is incorrect. Cautery is only effective for visible, localized anterior bleeding points in a relatively dry field. It is not appropriate for brisk, heavy bleeding or suspected posterior bleeds where the source cannot be clearly visualized.
Answer choice E: Topical thrombin, is incorrect. While topical hemostatic agents can be helpful adjuncts, they are rarely sufficient as a primary treatment for refractory arterial epistaxis that has already failed initial vasoconstriction.
Key Learning Point
The management of epistaxis follows a defined hierarchy:
Direct pressure (for 10–15 minutes) and topical vasoconstrictors (e.g., oxymetazoline).
Chemical cautery (silver nitrate) if the source is visualized and localized.
Anterior nasal packing if cautery fails or the source is not localized.
Posterior nasal packing (or balloon catheters) if blood is seen in the oropharynx or anterior packing fails.
Surgical ligation or embolization for truly refractory cases.
Patients with posterior packs require hospitalization and monitoring for potential complications, such as the nasopulmonary reflex or airway obstruction.
