Table 2.

Duration of surgery and use of vasopressors and inotropes. ^†Vasopressor use was expressed by the cumulative number of min in which a patient received phenylephrine, ephedrine, adrenaline, noradrenaline or dopamine i.v. during surgery. ^‡Inotrope use was expressed by the cumulative number of min in which a patient received milrinone or dobutamine i.v. during surgery. AUC, area under the curve; MAP, mean arterial pressure; IQR, interquartile range; sd, standard deviation
