Conditions

Anaesthesia in obese patients undergoing robot-assisted laparoscopic radical prostatectomy

Interventions

Using respiratory ventilation (Engstrom Caredtation, GE Healthcare), interventions start after Trendelenburg position and pneumoperitoneum were established. Using PC-VG mode, the target volume is set

I:E ratio of 1:2, PEEP of 5 cmH2O for 30 min. Conventional PC-IRV

I:E ratio of 4:1, PEEP of 0 cmH2O for 30 min. Practical PC-IRV

I:E ratio of 1.5:1, PEEP 5 cmH2O, for 30 min. High PEEP strategy

I:E ratio of 1:2, PEEP 10 cmH2O, for 30 min.
