Participant Flow

Participant milestones

Measure	Nicardipine Subjects will receive a 15 mcg/kg bolus of nicardipine as needed followed by an infusion initiated at 5 mg/hr. Nicardipine may be titrated every 5 minutes, increasing 5 mg/hr and administering 15 mcg/kg bolus every minute to a maximum dose of 15 mg/hr. If SBP is not maintained \< 140 mmHg 5 minutes after achieving the maximum dose of nicardipine, medication "failure" will be declared and rescue drug (medication to be determined per anesthesiologist discretion) will be administered. Infusions may be titrated down if SBP decreases below 90 mmHg.	Esmolol Subjects will receive a 0.5 mg/kg bolus of esmolol as needed followed by an infusion initiated at 50 mcg/kg/min. Esmolol may be titrated every 5 minutes, increasing 50 mcg/kg/min and administering 0.5 mg/kg bolus every minute to a maximum dose of 200 mcg/kg/min. If SBP is not maintained \< 140 mmHg 5 minutes after achieving the maximum dose of esmolol, medication "failure" will be declared and rescue drug (medication to be determined per anesthesiologist discretion) will be administered. Infusions may be titrated down if SBP decreases below 90 mmHg.
