What is the management approach for a patient with recurrent nose bleeds, elevated INR, prolonged PT, and elevated aPTT?

Management of a 21-Year-Old Male with Recurrent Nosebleeds and Coagulopathy

This patient requires immediate investigation for an underlying bleeding disorder or coagulopathy, with priority given to identifying the cause of the abnormal coagulation studies (elevated INR 1.5, prolonged PT 16.8 sec, elevated aPTT 44 sec) before implementing definitive epistaxis management. 1

Immediate Diagnostic Workup

Coagulation Assessment Priority

• Perform a mixing study (1:1 mix of patient plasma with normal plasma) immediately to differentiate between factor deficiency and an inhibitor such as lupus anticoagulant 2, 3
• If the mixing study corrects, measure Factor VIII, IX, XI, and XII levels to identify specific deficiencies 2
• If the mixing study fails to correct, perform specific lupus anticoagulant testing (dilute Russell viper venom time, hexagonal phase phospholipid neutralization) 2
• Verify no recent exposure to anticoagulants (warfarin, heparin, direct oral anticoagulants) through detailed medication history 1

Additional Laboratory Testing

• Check complete blood count to assess for thrombocytopenia, anemia from blood loss, and other cell line abnormalities 1
• Test for HIV, hepatitis C virus, hepatitis B virus, and Helicobacter pylori if immune thrombocytopenia is suspected 1
• Perform liver function tests to exclude hepatic synthetic dysfunction as a cause of coagulopathy 1
• Consider von Willebrand disease testing if family history suggests inherited bleeding disorder 1

Hereditary Hemorrhagic Telangiectasia Screening

Given the patient's young age and recurrent bilateral nosebleeds, assess for hereditary hemorrhagic telangiectasia (HHT) by examining for nasal and oral mucosal telangiectasias and obtaining family history of recurrent nosebleeds. 1, 4

• HHT occurs in 1 in 5,000 to 18,000 individuals and is frequently underdiagnosed 1
• Nosebleeds from telangiectasias are the main symptom in >90% of patients with HHT 1
• If HHT is suspected based on clinical findings, refer to a specialist with expertise in HHT management 1, 4

Epistaxis Management Strategy

First-Line Local Measures

Do not reverse anticoagulation, transfuse platelets, or administer clotting factors prior to attempting first-line interventions unless bleeding is life-threatening. 1

• Apply firm sustained compression to the lower third of the nose for 5-15 minutes with the patient seated and head tilted slightly forward 1, 4
• After compression, clean the nasal cavity of clots and apply topical vasoconstrictor (oxymetazoline or phenylephrine) spray 4
• Perform anterior rhinoscopy to identify the bleeding source after removal of any blood clot 1

Nasal Cautery Considerations

• If a bleeding site is identified, anesthetize the area and restrict cautery application only to the active or suspected bleeding site 1
• Use 75% silver nitrate rather than 95% concentration, as it achieves higher complete resolution rates and causes less pain 4
• Avoid bilateral simultaneous septal cautery due to increased risk of septal perforation 4

Packing Selection

Use resorbable packing for patients with suspected bleeding disorders or abnormal coagulation studies. 1

• Resorbable packing avoids the need for removal procedures that could precipitate rebleeding 1
• If non-resorbable packing is placed, educate the patient about the type of packing, timing and plan for removal, postprocedure care, and signs requiring prompt reassessment 1

Management Based on Bleeding Severity

Non-Severe Bleeding (Current Presentation)

• Do not give additional doses of anticoagulant or antiplatelet medications while bleeding is active 1
• Do not reverse anticoagulation or transfuse platelets if bleeding can be controlled with local measures 1
• Initiate first-line treatments (compression, vasoconstrictors, cautery) before considering blood products or reversal agents 1

Severe Bleeding Criteria (If Present)

Severe bleeding is defined by any of the following 1:

• Posterior nosebleed
• Hemodynamic instability due to blood loss
• Hemoglobin decrease ≥2 g/dL or requirement of 2 units of RBCs

If severe bleeding occurs 1:

• Initiate appropriate local measures to control bleeding and stabilize the patient
• Administer appropriate reversal agent based on identified anticoagulant
• Assess for and treat other contributory comorbidities (thrombocytopenia, uremia, liver disease)
• Consult with hematology regarding hemostatic management

Specific Reversal Strategies (If Needed)

For Vitamin K Antagonists (Warfarin)

• Fresh frozen plasma, 4-factor prothrombin complex concentrate (PCC), or vitamin K 1
• 4-factor PCC has shorter time to INR correction and smaller volume to infuse 1
• Intravenous or oral vitamin K can be used in non-severe bleeding 1
• Treatment should be based on bleeding severity in combination with INR 1

For Heparin Products

• Unfractionated heparin: Protamine sulfate 1 mg per 100 units of heparin administered in the last 2-3 hours (maximum 50 mg) 1, 5
• Low molecular weight heparin: Protamine sulfate 1 mg per 1 mg of enoxaparin administered in the last 8 hours (note: only partially effective) 1, 5

Common Pitfalls to Avoid

• Do not use INR to guide management in patients not on vitamin K antagonists, as INR is only validated for warfarin monitoring 1, 6
• Do not delay local hemostatic measures while waiting for laboratory results or reversal agents 1, 5
• Do not ignore mild coagulation abnormalities in patients requiring invasive procedures, as even mild coagulopathy can increase bleeding risk 2
• Do not confuse lupus anticoagulant (thrombotic risk) with bleeding risk—the name is misleading 2

Preventive Measures and Patient Education

Once acute bleeding is controlled and underlying coagulopathy is addressed, educate the patient about preventive measures. 1, 4

• Apply petroleum jelly or saline gel to the anterior nasal septum 1-3 times daily, particularly before bedtime 4
• Use regular saline nasal sprays to maintain mucosal moisture 4
• Consider bedside humidification during sleep 4
• Avoid digital trauma (nose picking) and forceful nose blowing for at least one week after treatment 1, 4
• Educate about proper first aid technique: pinching lower third of nose for full 15 minutes 4
• Instruct to seek emergency care if bleeding is not controlled after 15 minutes of compression 4

Follow-Up and Monitoring

• Document the outcome of intervention within 30 days to assess treatment effectiveness 1
• Arrange hematology consultation for definitive diagnosis and management of the underlying coagulopathy 1
• Monitor for recurrent bleeding and adjust preventive strategies accordingly 1
• If HHT is diagnosed, establish long-term management plan with appropriate specialist 1
