Admitting Diagnosis:  ____________________    Allergies:  ____________________
Check appropriate box(es) and complete blank lines.
•    Candidates for perioperative anti-ischemic prophylaxis:     All patients who have coronary artery disease (CAD), peripheral vascular disease (PVD) or two of the following risk factors for CAD:  age>65 years, cigarette smoking, diabetes, hypertension, cholesterol ≥ 240 mg/dl, chronic renal failure.
•    Contraindications to beta-blockers (BB):     uncompensated congestive heart failure (CHF), second or third degree heart block, uncontrolled asthma/chronic pulmonary disease, pheochromocytoma, documented allergy to BB
•    Patients with unstable angina, uncompensated  CHF, aortic stenosis will benefit from further evaluation by a cardiologist prior to instituting BB or going to surgery

Ideally, BBs should be titrated to a dose that maintains HRs of 55-80 and SBP > 100 mm Hg. For small patients (<50 kg), elderly, frail, HR < 65 or SBP < 100 consider dosing metoprolol at 25 mg po bid or atenolol 25 mg po daily.  For others metoprolol 50 mg po bid or atenolol 50 mg po daily is appropriate.

Pre-operative Therapy:
Patient to take usual dose of beta-blocker day of surgery
Identify drug, dose, route, frequency    ______________________________
Patient to start oral beta-blockade as soon as identified as cardiac risk
Atenolol 25 mg po daily        Metoprolol 25 mg po bid
Atenolol 50 mg po daily        Metoprolol 50 mgC po bid
Hold for systolic blood pressure (SBP) < 100 or heart rate (HR) < 55
a.  Clonidine 0.2mg po night before surgery as well as Clonidine TTS#2 Patch (0.2mg/24 hours).  Hold for SBP < 120 mm Hg.
b.  Clonidine 0.2 mg po morning of surgery
c.  Leave patch on for 1 week

Immediate Preoperative Period:
For all patients at risk for CAD who did not receive prior BB, anesthesiology will give IV metoprolol 5 mg every 10 minutes to target HR < 80 before induction

Post-operative Period:
Continue home maintenance beta-blocker therapy
Identify drug, dose, route, frequency    ______________________________
Oral therapy (rec. continuing up to 30 days or indefinitely if history of MI, angina)
Atenolol 25 mg po daily        Metoprolol 25 mg po bid
Atenolol 50 mg po daily        Metoprolol 50 mp po bid
Hold for SBP < 100 or HR < 55
For NPO patients:  metoprolol 5 mg IV q 4 hours prn HR > 80
If patient has not been on BB previously, monitor HR and BP q 5 min x 3, q 15 min x 3, q 30 min x2.  Hold for SBP < 100 or HR < 55.  Switch to oral when able, overlapping first dose with IV dose.
For ICU patients who are NPO: start esmolol at 100 mcg/kg.min (no bolus) and titrate up in increments of 50 mcg to 300 mcg/kg/min to maintain HR < 80.  May be titrated in OR, PACU or ICU.
