Outcome Measures

Primary Outcomes (2)

  • IOP

    IOP is directly assessed by measurement of IOP with the Tono-Pen AVIA®

    Changes from pre-induction (baseline) at Post-induction 5 min, Pneumoperitoneum insufflation and Trendelenburg position 5 min, Pneumoperitoneum insufflation and Trendelenburg position 30 min, Penumoperitoneum desufflation and supine position 5 min

  • ICP

    ICP is indirectly assessed by measurement of optic nerve sheath diameter(ONSD) with the ultrasound

    Changes from pre-induction (baseline) at Post-induction 5 min, Pneumoperitoneum insufflation and Trendelenburg position 5 min, Pneumoperitoneum insufflation and Trendelenburg position 30 min, Penumoperitoneum desufflation and supine position 5 min
