Preparedness: Your Guide to Emergencies, Dental Work, and Surgery

Last updated:

Patients with Glanzmann Thrombasthenia must proactively prepare for emergencies by carrying a formal emergency letter detailing their diagnosis and antibody status. Key safety measures include keeping a "go-bag" with antifibrinolytics and coordinating directly with a hematologist before any dental work or surgery to manage bleeding risks.

Key Takeaways

  • • Carry a hematologist-signed emergency letter stating your GT subtype, antibody status, and specific treatment protocols at all times.
  • • Maintain an emergency 'go-bag' containing antifibrinolytics (like TXA), hemostatic gauze, and nose clips for immediate use.
  • • Dental extractions require a coordinated plan including local hemostatics and antifibrinolytic mouthwash to prevent bleeding.
  • • Strictly avoid NSAIDs (like ibuprofen) and intramuscular injections, as these can significantly worsen bleeding risks.
  • • Surgeries require a pre-operative 'huddle' between your medical team to plan for clotting support, often involving rFVIIa or platelet transfusions.

When you have Glanzmann Thrombasthenia (GT), the best way to handle an emergency is to have already finished the “paperwork” for it. Because GT is so rare, most ER doctors and dentists may never have treated a patient with it. You must be your own best advocate by being prepared with the right tools and information [1][2].

The Essential Emergency Letter

Your hematologist should provide you with a formal “Emergency Letter.” This is not just a note; it is a roadmap for your care. It should include:

  • The Diagnosis: Clearly stating “Glanzmann Thrombasthenia” and the subtype (Type I, II, or III) [3].
  • Antibody Status: Whether you have antibodies to HLA or GPIIb/IIIa, which tells the ER doctor if regular platelets will work or not [4][5].
  • Treatment Priority: A clear instruction to use rFVIIa (NovoSeven) or Antifibrinolytics (TXA) as first-line treatments if appropriate, to avoid unnecessary platelet transfusions [6][7].
  • What NOT to do: Explicit warnings against intramuscular (IM) injections and NSAIDs (like Ibuprofen or Aspirin), which can worsen bleeding [8].
  • Contact Info: Direct, 24/7 contact information for your hematology team [8][9].

Your GT ‘Go-Bag’

Always have a bag ready for the ER or travel. It should contain a mix of Over-the-Counter (OTC) and Prescription (Rx) items.

Prescription Items (Must be provided by your doctor)

  1. Antifibrinolytics: A supply of tranexamic acid (TXA) or aminocaproic acid (Amicar) pills [6][10].
  2. Emergency Letter: The original signed document [8].

Over-the-Counter / Standard Items

  1. Local Hemostatics: Products like nasal plugs or hemostatic gauze (often found in pharmacies) to help apply pressure [11].
    • Note: Specialized hospital-grade hemostatics like Thrombin or Gelfoam are typically only available in a clinical setting.
  2. Nosebleed Tools: Specialized nose clips (like nosebuddies) to apply constant pressure without you having to hold it [11].
  3. Identification: Your medical ID bracelet worn at all times [12].

Dental Care: The Protocol for Extractions

Dental work is a major concern for GT patients, but with a plan, it can be managed safely.

  • Preventive Care: Regular cleanings are vital to prevent the need for extractions.
  • The Extraction Plan: If a tooth must come out, the “Huddle” between the dentist and hematologist is mandatory [8][13].
  • Local Protection: The dentist may use a custom soft splint or stent to protect the area while it heals [14].
  • Clot Support: Using fibrin glue or a tranexamic acid mouthwash can keep the clot in place without needing a full blood transfusion [15][8].

Major Surgery: The ‘Huddle’

For any surgery, your surgeon, hematologist, and anesthesiologist must meet (the “huddle”) to create a minute-by-minute plan [8][9].

  • Pre-Surgical Dose: You may receive a dose of rFVIIa or platelets just before the first incision [16][7].
  • The “Backdoor” Method: Using rFVIIa during surgery can help create a “thrombin burst” to keep bleeding under control even if your platelets aren’t working [7][17].
  • Post-Op Monitoring: You will likely need to stay in the hospital longer to ensure no “delayed” bleeding occurs as your body begins to heal [18][9].

Remember: In an emergency, do not wait for the bleeding to become “severe” before seeking help. Early treatment with the right tools is the key to safety [1][2].

Frequently Asked Questions

What should be included in a Glanzmann Thrombasthenia emergency letter?
Your emergency letter serves as a roadmap for ER doctors who may be unfamiliar with this rare condition. It should clearly state your diagnosis (including subtype), antibody status to guide transfusion decisions, priority treatments like rFVIIa or antifibrinolytics, and explicit warnings against NSAIDs and intramuscular injections.
How can I safely handle dental extractions with Glanzmann Thrombasthenia?
Dental work requires a coordinated plan between your dentist and hematologist. The protocol often involves using preventive measures, custom splints to protect the site, and local clot-supporting agents like fibrin glue or tranexamic acid mouthwash to prevent excessive bleeding.
What items should I pack in my GT emergency go-bag?
Your go-bag should contain both prescription items like tranexamic acid (TXA) or aminocaproic acid (Amicar) and over-the-counter tools. Essential items include your emergency letter, local hemostatics like nasal plugs or gauze, nose clips for applying pressure, and your medical ID bracelet.
Which medications should be avoided if I have Glanzmann Thrombasthenia?
NSAIDs (Non-Steroidal Anti-Inflammatory Drugs) like Ibuprofen and Aspirin must be avoided because they interfere with platelet function and can worsen bleeding. You should also avoid intramuscular (IM) injections, which can cause bleeding into the muscle.
What is the surgical protocol for patients with Glanzmann Thrombasthenia?
For major surgery, your surgeon, hematologist, and anesthesiologist should meet to create a specific management plan. This often involves pre-surgical doses of rFVIIa or platelets and possibly using rFVIIa during surgery to create a 'thrombin burst' that helps control bleeding even when platelets aren't working.

Questions for Your Doctor

  • • Can we review and update my (or my child's) emergency letter to ensure it reflects our most recent antibody status?
  • • Who is the 'on-call' hematologist I should contact if I am admitted to an ER that doesn't know my history?
  • • For my next dental procedure, can we coordinate with the dentist to use local hemostatic agents like fibrin glue or a custom splint?
  • • If I need an emergency surgery, do you have a preference for using rFVIIa (NovoSeven) over platelet transfusions to avoid antibody formation?
  • • Are there any hospitals in our area that you specifically recommend for emergencies because they are familiar with platelet disorders?

Questions for You

  • • Do I have my 'Emergency Go-Bag' packed and easily accessible, and does everyone in my household know where it is?
  • • Is my medical ID jewelry up-to-date and clearly stating 'Glanzmann Thrombasthenia'?
  • • When was the last time I checked the expiration dates on the emergency medications (like TXA) in my go-bag?
  • • Does my dentist have a direct phone number for my hematologist in their file?
