What are the recommendations for blood pressure maintenance during a carotid endarterectomy?
A. During a carotid endarterectomy, it is advised to maintain the patient’s MAP slightly above their highest recorded preoperative pressure. For severe hypertension, labetolol may be used, but nitroglycerin is preferred for its swift onset and short duration of action as labetolol could result in postoperative hypotension due to its long duration of action. For hypotension, a pure alpha-agonist such as phenylephrine is preferred because it has minimal dysrhythmogenic potential.
