A 58-year-old man with a history of angina is undergoing resection of an abdominal aortic aneurysm under morphine, nitrous oxide, d-tubocurarine anesthesia. Just before removal of the aortic cross-clamp, heart rate is 74 bpm, blood pressure is 115/70 mmHg, and pulmonary artery occlusion pressure is 7 mmHg. Immediately after removal of the cross-clamp, heart rate increases to 120 bpm, blood pressure decreases to 80/55 mmHg, and pulmonary artery occlusion pressure decreases to 3 mmHg. The V5 lead on the EKG demonstrates sudden ST-segment depression and T-wave inversion. Initial therapy should be
(A) reapplication of the aortic cross-clamp
(B) intravenous administration of sodium bicarbonate
(C) initiation of a phenylephrine infusion
(D) rapid expansion of blood volume by transfusion
