Study population

Patient who need a surgery in supine position and who don't have brain injured or pulmonary desease.

Forty patients over 24 month period were included in the study, after informed consent.

Pulsatility index is mesured with doppler ultrasound:

  2. after general anesthesia in dorsal position
  3. in supine position
  4. in supine position with 15° proclive Evaluation to the pulsatility index changes in theese position

  • minimum 18 years old, maximum 45 years old for men and 55 years old for women.
  • surgery with supine position.

Exclusion criteria

Exclusion Criteria:

  • refusal to participate
