The Anticoagulated Patient and a Surgical Extraction

General principle: For most routine dental procedures - including simple and many surgical extractions - DOACs such as apixaban are continued, not interrupted. Interruption without coordination with the prescriber exposes the patient to thromboembolic risk (stroke with AF), and the bleeding from a dental extraction is generally controllable with local measures.

Reasoning specific to this case:

• The procedure is a surgical extraction with bone removal - higher bleeding risk than a simple extraction, but still generally manageable with local hemostasis.
• Do not unilaterally stop an anticoagulant based on a closed cardiology office. The decision to interrupt requires prescriber input and a plan for timing of resumption.
• INR is irrelevant here; apixaban does not require INR monitoring. Do not be reassured or alarmed by a 'normal INR.'
• Renal function matters for apixaban clearance; in the absence of known renal disease and with a normal-appearing history, risk is lower, but this should be confirmed when possible.

Local hemostatic plan:

• Atraumatic technique; minimize tissue trauma.
• Sutures to approximate tissue.
• Hemostatic agent in the socket (e.g., oxidized cellulose, gelatin sponge, or collagen plug) and/or topical tranexamic acid.
• Pressure with gauze for an adequate period.
• Consider tranexamic acid mouthwash postoperatively.
• Clear postoperative instructions: no vigorous rinsing, no smoking, avoid NSAIDs if possible, and a contact plan if bleeding occurs.

Bottom line: proceed with local hemostatic precautions and continue apixaban, while making every effort to reach the prescriber for confirmation and documentation.

Stepwise management of post-extraction bleeding on a DOAC:

1. Assess: Is this oozing or active hemorrhage? Check vital signs, look for a hematoma or expanding swelling, assess the airway (especially with a posterior mandibular site), and estimate blood loss. Oozing that stops with pressure is different from a spurting vessel or a rapidly expanding hematoma.
2. Local measures first:
   • Remove the old clot/gauze, identify the bleeding source.
   • Reapply firm pressure with gauze for 20–30 minutes.
   • If persistent, re-anesthetize and re-explore the socket; place additional hemostatic agent; suture if not already done; consider a tranexamic acid-soaked gauze or mouthwash.
   • Consider electrocautery or a hemostatic dressing for a discrete bleeding point.
3. Medication review: Confirm the last apixaban dose and timing; ask about other agents (NSAIDs, aspirin, supplements).
4. Escalation triggers:
   • Bleeding not controlled after repeated local measures.
   • Signs of significant blood loss (tachycardia, hypotension, dizziness, pallor).
   • Airway compromise or expanding hematoma.
   • Suspected coagulopathy or renal impairment. → Refer to the emergency department for evaluation, possible reversal/consultation with hematology or cardiology, and monitoring.
5. Communication: Contact the prescriber as soon as possible; document everything.

Judgment point: the exam tests that you exhaust local measures and know your escalation triggers rather than reflexively stopping the anticoagulant or sending every oozer to the ED.
