a Changes in mean arterial blood pressure (MAP) and heart rate (HR). b Changes in percutaneous (SpO2) and arterial (SaO2) oxygen saturation. c Changes in arterial oxygen tension (PaO2). d Changes in carbon dioxide tension (PaCO2). e Changes in left cerebral regional oxygen saturation (rSO2). f Changes in right cerebral regional oxygen saturation (rSO2). Pre: before the induction of anesthesia, Pre-P: just before the pneumoperitoneum, P-5, 10: 5, 10 min after the pneumoperitoneum, Pre-T: just before the Trendelenburg position (approximately 15 min after the pneumoperitoneum), T-5, 10, 20, 30, 45, 60: 5, 10, 20, 30, 45, 60 min after the Trendelenburg position. * P < 0.05, compared with Pre-P, † p < 0.05, compared with Pre-T, # P < 0.05, compared with other time points
