Which statement about epinephrine use in hypertensive patients is true?

• A. It is contraindicated in all hypertensive patients
• B. It is contraindicated only in uncontrolled hypertension
• C. It is not contraindicated in a controlled hypertensive patient
• D. It should be avoided entirely

Answer: (C)

The key idea is how a patient’s blood pressure status affects the safety of using epinephrine as a vasoconstrictor in local anesthesia. Epinephrine helps keep the anesthetic localized, reduces bleeding, and prolongs the numbness, but it also can cause a temporary rise in blood pressure and heart rate by stimulating various receptors. When hypertension is well controlled, that transient BP and HR rise is generally well tolerated, especially if the dose of epinephrine is kept to the minimum effective amount. In this scenario, using an epinephrine-containing anesthetic is not a contraindication because the body’s regulation is stable and the risks are manageable with standard precautions—careful dosing, limiting the total amount administered, and monitoring the patient. If hypertension is uncontrolled, or if there are significant cardiovascular problems, the risk increases, and the clinician might avoid epinephrine or use alternatives and obtain medical input. This nuance is what makes the statement about controlled hypertension the true one: controlled hypertension is not a blanket contraindication to epinephrine in dental anesthesia. So, the correct understanding is that epinephrine can be used in a patient with controlled hypertension, with appropriate dosing and monitoring, rather than being categorically avoided or deemed unsafe in all hypertensive patients.
