Management of Persistent Bleeding After Multiple Tooth Extractions

Initial Assessment and Immediate Actions

Assess bleeding severity first to determine the appropriate management pathway (American College of Cardiology) 1.
If bleeding persists despite initial compression, immediately discontinue all oral anticoagulants (warfarin, DOACs) and antiplatelet agents (American College of Cardiology) 3.
Evaluate for hemodynamic instability (hypotension, tachycardia) and for major blood loss defined as a hemoglobin drop ≥ 2 g/dL (American College of Cardiology) 1.
Screen for underlying coagulopathy contributors such as thrombocytopenia, uremia, or liver disease (American College of Cardiology) 3.

Apply a gauze soaked in 10 mL of 5 % tranexamic acid with firm compression for 20–30 minutes (American College of Chest Physicians) 4.
Place sutures across all extraction sites promptly; early suturing is essential after extensive extractions (American College of Chest Physicians) 4.

Give 5–10 mg intravenous vitamin K immediately (American College of Cardiology) 1.
Consider prothrombin complex concentrate (PCC) for life‑threatening or hemodynamically significant bleeding (American College of Cardiology) 1.

Do not administer reversal agents for non‑major bleeding; local measures are sufficient (American College of Cardiology) 5.
For major or life‑threatening bleeding, use specific reversal agents (idarucizumab for dabigatran; andexanet alfa for apixaban/rivaroxaban) (American College of Cardiology) 1.

Maintain hemodynamic stability with intravenous fluid resuscitation as needed (American College of Cardiology) 1.
Monitor hemoglobin/hematocrit serially to detect ongoing blood loss (American College of Cardiology) 1.
Transfuse packed red blood cells if hemoglobin falls ≥ 2 g/dL or if ≥ 2 units are required (American College of Cardiology) 1.

Continue bleeding despite maximal local hemostatic measures warrants escalation (American College of Cardiology) 1.
Development of hemodynamic instability (e.g., hypotension, tachycardia) mandates escalation (American College of Cardiology) 1.
Requirement for blood transfusion indicates need for higher‑level intervention (American College of Cardiology) 1.
Consult oral surgery or ENT for possible vessel ligation, cauterization, or re‑exploration of extraction sites (American College of Cardiology) 1.

Do not continue anticoagulation during active bleeding; temporary cessation is required (American College of Cardiology) 3.
Do not use DOAC reversal agents for non‑major bleeding because they carry a thrombotic risk and are unnecessary when local measures are applied (American College of Cardiology) 5.

Instruct the patient to continue biting a tranexamic‑acid‑soaked gauze for a period longer than the standard 30 minutes (American College of Chest Physicians) 4.
Prescribe tranexamic‑acid mouthwash, 10 mL three times daily for 1–2 days (American College of Chest Physicians) 4.
Delay restarting anticoagulation until extraction sites are stable and the risk of re‑bleeding is low (American College of Cardiology) 1.
