QOD 11 6 09

Which one of the following postoperative complications has been most commonly associated with the use of coronary-artery bypass grafting (CABG) involving cardiopulmonary bypass ("on pump" CABG)?
		A.	Adrenal insufficiency.
		B.	Cerebral dysfunction.
		C.	Gastric ulceration.
		D.	Reactive thrombocytosis During the past 30 years, coronary-artery bypass grafting (CABG) primarily was performed with the use of cardiopulmonary bypass ("on pump") with cardioplegic arrest. Historically, on-pump CABG was shown to improve ischemic symptoms and, in selected patients, prolong survival. In the mid-1990s, interest emerged in performing CABG without the use of cardiopulmonary bypass (off pump), in order to reduce postoperative complications associated with the use of cardiopulmonary bypass, including generalized systemic inflammatory response, cerebral dysfunction, myocardial depression, and hemodynamic instability.
