The Medically Complex Patient Needing an Extraction
A 70-year-old man requires extraction of tooth 47 due to a non-restorable fracture. His medical history includes a myocardial infarction 18 months ago, stable angina, hypertension, and type 2 diabetes. His medications include clopidogrel, a beta-blocker, an ACE inhibitor, and metformin. He reports no chest pain at rest and no shortness of breath. His blood pressure today is 148/88 mmHg and his heart rate is 72. He has no known allergies. He is unsure whether his cardiologist wants him to stop clopidogrel before the procedure. He has not had a recent HbA1c check.
1. How do you assess his medical risk before proceeding with the extraction?
Read the worked answer
Assess cardiovascular risk using his history: a myocardial infarction 18 months ago is beyond the highest-risk early period, and his angina is stable with no rest pain. His blood pressure is elevated but not in a hypertensive crisis range; proceed with caution and monitor. Review his medications and confirm adherence. The key question is antiplatelet management: clopidogrel should generally not be stopped for a simple extraction because the thrombotic risk outweighs bleeding risk, but this should be confirmed with his cardiologist. Check his diabetes control with a recent HbA1c if available, since poor control affects healing and infection risk. The judgment is to gather information and coordinate rather than proceed blindly or cancel unnecessarily.
2. What is your recommendation regarding clopidogrel, and how do you justify it?
Read the worked answer
Recommend continuing clopidogrel and not stopping it for the extraction. Clopidogrel is used for secondary prevention after myocardial infarction and possibly with a stent; stopping it increases the risk of stent thrombosis or recurrent cardiovascular events, which can be catastrophic. The bleeding risk from a single dental extraction is generally manageable with local measures: atraumatic technique, suturing, pressure, and topical hemostatic agents. Coordinate with his cardiologist to confirm the indication and any specific instructions, and document the communication. If the cardiologist advises otherwise, follow that guidance. The judgment is that the systemic thrombotic risk outweighs the local bleeding risk in most cases.
3. Outline the intraoperative and postoperative plan to minimize risk.
Read the worked answer
Intraoperatively: use effective local anesthesia, monitor blood pressure and heart rate, and use an atraumatic technique to minimize bleeding. Have hemostatic agents available and suture if needed. Keep the appointment short and allow the patient to rest afterward. Postoperatively: provide clear instructions, including pressure and what to do if bleeding persists. Advise him to continue his medications as directed. Schedule follow-up to check healing, and remind him to maintain diabetes control. Provide an emergency contact. Escalate if he develops chest pain, severe bleeding, or signs of infection. Document the plan and the coordination with his physician.
