Postoperative Hypertension Management

Immediate Postoperative Assessment

The American College of Cardiology recommends evaluating and addressing reversible causes that commonly drive postoperative hypertension, such as pain control, volume status, and bladder distention, before initiating pharmacologic therapy 2
Volume status, including both hypovolemia and hypervolemia, can cause blood pressure lability 4
Bladder distention can cause reflex hypertension 2

The American College of Cardiology recommends maintaining systolic BP >90 mm Hg or MAP ≥60-65 mm Hg as the minimum threshold to avoid myocardial injury, acute kidney injury, and mortality 1
Higher blood pressure targets may be appropriate for patients with chronic hypertension or older adults to maintain organ perfusion 1

The American College of Cardiology recommends continuing beta-blockers and clonidine perioperatively to avoid rebound hypertension and sympathetic surge 2, 3
The American College of Cardiology suggests considering holding ACE inhibitors and ARBs 24 hours before surgery due to association with intraoperative hypotension, but resuming them as soon as clinically possible postoperatively to reduce 30-day mortality 2, 3, 5
The European Society of Cardiology recommends considering discontinuation of ACE inhibitors and ARBs to reduce hemodynamic instability 5

The American College of Cardiology recommends using intravenous agents with rapid onset, short duration, and easy titratability, such as nicardipine, labetalol, and clevidipine, when oral medications cannot be administered 2
Nicardipine is highly effective for postoperative hypertension, with a mean time to therapeutic response of 12 minutes 2, 3
Clevidipine may be more effective than other agents without adverse events, based on meta-analysis of cardiac surgery patients 2, 3

The American College of Cardiology recommends not delaying resuming chronic antihypertensive medications, as ongoing treatment reduces 30-day mortality 1, 4
The American College of Cardiology advises against starting beta-blockers on the day of surgery in beta-blocker-naïve patients, as this is potentially harmful 2
The American College of Cardiology suggests monitoring for intraoperative hypotension more carefully in patients taking ACE inhibitors/ARBs, as these patients are at higher risk for profound hypotension during anesthesia induction 5
