Treatment and study plan

Position

Procedure

Pneumoperitoneum with Steep Trendelenburg position

Primary outcomes

  1. Difference in internal carotid artery blood flow

    Time frame: At 10 minutes after pneumoperitoneum with steep Trendelenburg position

Secondary outcomes

  1. Internal carotid artery blood flow

    Time frame: Baseline (Before anesthetic induction)

    Internal carotid artery blood flow before anesthetic induction

  2. Internal carotid artery blood flow

    Time frame: At 10 minutes after anesthetic induction

    Internal carotid artery blood flow at 10 minutes after anesthetic induction

  3. Internal carotid artery blood flow

    Time frame: At 10 minutes after pneumoperitoneum and Trendelenburg position

    Internal carotid artery blood flow at 10 minutes after pneumoperitoneum and Trendelenburg position

  4. Internal carotid artery blood flow

    Time frame: At 30 minutes after pneumoperitoneum and Trendelenburg position

    Internal carotid artery blood flow at 30 minutes after pneumoperitoneum and Trendelenburg position

  5. Internal carotid artery blood flow

    Time frame: Procedure (At skin closure)

    Internal carotid artery blood flow during supine position at skin closure
