The most frequent cognitive function disorders after cardiopulmonary bypass are concentration, attention and memory deficits. The effects of early extubation on these parameters are not clarified yet. The aim of this study is to investigate the effects of fast-track and classical opioid anesthesia on the short term memory functions and depression of the patients undergoing coronary artery bypass surgery. Forty patients scheduled for coronary surgery who were free from psychiatric disturbances and at least graduated from primary school, were included in the study. Twenty patients received classical opioid anesthesia and another 20 received fast-track anesthesia. For short term memory functions and depression evaluation, the patients were tested with Visual Aural Digit Span Test form-B and Beck Depression Inventory 3 times: preoperatively, 1st and 5th days after surgery. Postoperative 1st day scores of Visual Aural Digit Span Test components including; visual-oral, visual-written, visual-stimulation, oral and written expression, intersensory-integration were significantly lower than the preoperative score (p< 0.05) in classical anesthesia group. When two groups are compared, patients in classical opioid anesthesia group showed decline regarding visual-written, visual-stimulation, written-expression and intrasensory-integration functions on postoperative 1st day. There were no significant differences in preoperative and postoperative Beck depression test scores between or within two groups. In conclusion, when two groups were compared, fast-track anesthesia seems more advantageous concerning cognitive function on the postoperatively, but it does not have any effect on depression.
