Answer

The trachea should be intubated orally because nasal intubation may cause significant bleeding once heparin is administered. A double-lumen endotracheal tube is required if CABG is being performed via a left thoracotomy.

Central venous access should be obtained, as it is not uncommon for the patient to become hypotensive. To ensure that there is sufficient diastolic pressure to maintain coronary perfusion, hypotension should be treated with IV fluids or with an alpha agonist if left ventricular function is depressed.
