Fig. 2. Fluid-management protocol synopsis. All patients received a base rate of 2 ml · kg−1· h−1crystalloid infusion. If anesthetic depth was adequate, an additional 5-min bolus infusion of 250 ml Jonosteril® (Fresenius Kabi AG, Bad Homburg, Germany) was triggered by a set of criteria: hypotension, tachycardia, or high Pleth Variability Index (PVI). BIS = bispectral index; bpm = beats/min; HR = heart rate; MAP = mean arterial pressure; PPC = peristaltic pneumatic compression; SAP = systolic arterial pressure.
