Measurements of the Cerebral Oxygen Profiles and Hemodynamic Variables during Study Periods

SjvO₂, jugular bulb oxygen saturation; rSO₂, regional cerebral oxygen saturation; MAP, mean arterial pressure; HR, heart rate.

Values are mean±SD. T₁ and T₂, PaCO₂ of 35 and 45 mm Hg in supine position, respectively; T₃ and T₄, PaCO₂ of 35 and 45 mm Hg in the Trendelenburg position under pneumoperitoneum, respectively.

^*p<0.05 and ^†p<0.001 compared with the value at T₁.

^‡p<0.001 compared with the value at T₃.
