Objective: This study aimed to evaluate the effect of the beach-chair position on intraoperative cerebral oxygenation and postoperative cognitive functions in different age groups by comparing the data of patients who were under 65 years of age with those >= 65 years of age. Design: Prospective cross-sectional study Setting: Department of Anesthesiology and Reanimation, Hacettepe University Medical School, Ankara, Turkey. Subjects: Fifty patients who underwent shoulder surgery were included in the study. Intraoperative hemodynamic and brain oxygenation were measured with invasive arterial blood pressure monitoring and Near-Infrared Spectroscopy (NIRS). Neurocognitive functions were evaluated using the Mini-Mental Test (MMT). Intervention: The first test (MMT1) was performed during the preoperative evaluation and the second test (MMT2) was performed within the first 24 hours after the operation. Main outcome measure: Preoperative (MMT1) and postoperative (MMT2) MMT results were similar when evaluated between groups (P=0.377). P =0.377). Results: There was no statistically significant difference between the groups in terms of NIRS, blood pressure, heart rate or end-tidal carbon dioxide values at any time. Preoperative (MMT1) and postoperative (MMT2) MMT results were similar when evaluated between groups ( P =0.377). Conclusions: The beach chair position during shoulder surgery was found to result in hemodynamic fluctuations regardless of the patients' age, and a change in brain tissue oxygenation which parallels the fluctuations in hemodynamic parameters was observed. The MMT test results were similar in both age groups.
