Hemodynamic algorithm for the photoplethysmography group. *Norepinephrine after the failure of the use of ephedrine, which is defined by the use of 30 mg of ephedrine without the desired hemodynamic response. Norepinephrine: dosage began at 0.05 μg/kg/min and then was adjusted in steps of 0.05 μg/kg/min. MAP, mean arterial pressure
