During routine general anesthesia (not standardized, left to the discretion of the attending anesthesiologist), pupillary pain index was measured one minute before skin incision. Then, variations in heart rate, blood pressure and bispectral index during the three minutes following skin incision were recorded, as well as the occurrence of movements.
