Developmental phase



Assessment

Primary outcomes

Association between the percent decrease in the pupil diameter following a small dose of fentanyl and remifentany consumption during surgery (normalized with ideal body weight and duration of anesthesia).
Association between the percent decrease in pupil diameter following a small dose of fentanyl and postoperative fentanyl consumption within 24 h after surgery (normalized with body weight).

Interventions/Control_1

We measure the pupil diameter before and after small dose of fentanyl just before induction of general anesthesia.
We adjust the doses of propofol and remifentanyl to maintain BIS value, blood pressure and heart rate within pre-determined ranges to provide general anesthesia during surgery.
We measure fentanyl consumption using an infusion pump with intravenous patient controlled- analgesia function until 24 h after surgery. We add rescue anti-nociceptive drugs according to a pre-determined protocol.
