Abstract
Any one of a number of psychologic patterns may appear after cardiotomy: (1) Some patients may be elated and confident after awakening from anesthesia and have no severe changes of affect or neurologic deficit. Denial seems to be for them an adequate defense against anxiety. (2) Others are disoriented and manifest neurologic disturbance immediately after awakening, without a lucid interval. The sensorium begins to clear five days after surgery. (3) Some patients go into delirium after being lucid for as long as a week and have hallucinations, illusions, and motor excitation for a few days—or over several weeks.
