Note: SjvO₂, jugular venous oxygen saturation; Da-jvO₂, arterial content and arterial-to-internal jugular difference; CERO₂, cerebral oxygen extraction rate. T1: 5 min before induction of anesthesia in recumbent position, T2: 5 min after CO₂ pneumoperitoneum in Trendelenburg position, T3: 30 min after CO₂ pneumoperitoneum in Trendelenburg position, T4: 60 min after CO₂ pneumoperitoneum in Trendelenburg position, T5: 5 min after the close of pneumoperitoneum in recumbent position.

Compared with T1;

P<0.05.
