Outcome Measures

Primary Outcomes (1)

  • Change of the common carotid artery blood flow velocity

    Common carotid artery blood flow velocity is measured using Doppler US

    1) baseline, 2) Immediately after induction of anesthesia, 3) immediately after pneumoperitoneum, 4) immediately after Trendelenburg position with penumoperitoneum, 5) Immediately after desufflation in Trendelenburg position

Secondary Outcomes (5)

  • Change of the common carotid artery beat volume

    1) baseline, 2) Immediately after induction of anesthesia, 3) immediately after pneumoperitoneum, 4) immediately after Trendelenburg position with penumoperitoneum, 5) Immediately after desufflation in Trendelenburg position

  • Change of the common carotid artery diameter

    1) baseline, 2) Immediately after induction of anesthesia, 3) immediately after pneumoperitoneum, 4) immediately after Trendelenburg position with penumoperitoneum, 5) Immediately after desufflation in Trendelenburg position

  • Change of mean arterial blood pressure

    1) baseline, 2) Immediately after induction of anesthesia, 3) immediately after pneumoperitoneum, 4) immediately after Trendelenburg position with penumoperitoneum, 5) Immediately after desufflation in Trendelenburg position

  • Change of cardiac output

    1) baseline, 2) Immediately after induction of anesthesia, 3) immediately after pneumoperitoneum, 4) immediately after Trendelenburg position with penumoperitoneum, 5) Immediately after desufflation in Trendelenburg position

  • Change of peak inspiration airway pressure

    1) baseline, 2) Immediately after induction of anesthesia, 3) immediately after pneumoperitoneum, 4) immediately after Trendelenburg position with penumoperitoneum, 5) Immediately after desufflation in Trendelenburg position
