Hemodynamic algorithm for the PVI group. *Norepinephrine after failure of the use of ephedrine defined by the use of 30 mg of ephedrine without desired hemodynamic response. Norepinephrine: dosage begins at 0.05 μg/(kg min), and is then adjusted in steps of 0.05 μg/(kg min). IV, intravenous; IVD, intravenous drip; MAP, mean arterial pressure; PVI, plethysmographic variability index
