Introduction: Surgeon’s performance may be influenced by several factors that may affect skills and judgement, which ultimately represents surgeon´s cognition. This study aims to evaluate the effect of operative time and operative complications on surgeon´s cognition. Methods: Fortysix surgeons (mean age 31 years, 78% males) assigned to an operation expected to last for at least 2 hours, volunteered for the study. All participants underwent 3 cognitive tests at the beginning of the operation and hourly, until the end of the procedure: (a) concentration (serial sevens, counting down from 100 by sevens); (b) visual (fast counting, counting the number of circles with the same color among a series of circles); and (c) motor (trail making, connecting a set of numbered dots). Intraoperative complications – defined as bleeding, organ injury or hemodynamic instability were recorded. Results: The visual test had a stable behavior along time. Concentration and motor tests tended to be performed faster. Intraoperative complications occurred in 5 (11%) cases (3 hemorrhage and 2 organ injuries). Performance time was stable for concentration and motor tests but visual test tended to be performed faster in cases with an intraoperative complication. Conclusion: Our results showed that: (1) time does not jeopardize surgeon´s cognition, but rather surgeons learned to perform the tests faster; and (2) complications do not decrease surgeon´s cognition.
