Objective: This study evaluates the importance of cross clamp time (CCT) on neurocognitive function in coronary artery bypass graft at an early postoperative period.

Methods: The standardized mini mental state examination (SMMSE) is used to determine the neurocognitive function. This is a prospective study on 100 consecutive patients within a certain time interval in a single clinic.

Results: During the study period 100 participants are analysed by SMMSE, preoperatively and postoperatively. The CCT under 120 min had no significant impact on neurocognitive function (p>0.05). Mean age (57.8±9.7). 82% men, 18% women. Median SMMSE point: 29±0.8 (preoperative), 29.2±0.8 (postoperative) (p>0.05). CCT is 62.6±27.8 min and cardiopulmonary bypass time is 82.3±32.4 min in this study.

Conclusion: We have found no correlation between CCT (median: 62±27 min) and neurocognitive function. The study implies that surgeons can relax in CCT under 120 min in terms of neurocognitive disorder.
