Esmolol or Nitroglycerin Infusion for Blood Pressure Control Prior to Cardiopulmonary Bypass (CPB) in Cardiac Surgery
This is an investigator initiated, sponsored, open label, prospective randomized controlled trial to be performed in adult patients undergoing scheduled cardiac surgery. Patients will be randomized to esmolol infusion or nitroglycerin infusion for control of hypertension that occurs during cardiac surgery from induction of anesthesia to initiation of cardiopulmonary bypass (CPB).
