Questions: In patients with hypertension undergoing major surgery who have been on beta blockers chronically, beta blockers should be continued.

The answer is True: In patients with hypertension undergoing major surgery who have been on beta blockers chronically, beta blockers should be continued.

Explanation:

• Beta blockers are commonly used to manage hypertension and other cardiovascular conditions. When patients have been on beta blockers chronically, their bodies have adapted to the medication.
• Abrupt discontinuation of beta blockers can lead to rebound hypertension, increased heart rate, and other cardiovascular complications, which can be particularly dangerous in the perioperative setting.
• Continuing beta blockers in the perioperative period helps maintain hemodynamic stability and reduces the risk of adverse cardiovascular events.
• Clinical guidelines generally recommend the continuation of beta blockers in patients who are already on them prior to surgery, unless there is a specific contraindication or adverse effect that necessitates stopping the medication.

In summary, for patients with hypertension undergoing major surgery who have been on beta blockers chronically, it is generally recommended to continue the medication to avoid potential complications.
