A symbol/language integration task and a memory scanning task were administered to two groups of surgical patients (aortic reconstruction and laparoscopy) and to aged-matched nonsurgical controls, 1 week prior to surgery, on the day of discharge from the hospital, and 2 and 8 weeks after discharge. In patients undergoing aortic reconstruction, a significant impairment of cognitive processing (as detected preoperatively) was accentuated at time of discharge. Significant improvement in performance on both tasks was found, however, in the 2- and 8-week postdischarge sessions. In fact, during these later sessions, performance on the memory scanning task became equivalent to that of control participants. Thus, pre- and postoperative impairments in patients undergoing repair of an aortic aneurysm do not appear to be the consequence of short-term memory loss per se, but may be related to a more general slowing of the information processing system.
