Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Before starting operation a passive leg raising is performed. The passive leg raising maneuver (PLR) involves a leg elevation up to 45° with the trunk in a horizontal position and was performed to induce hemodynamic effects by a volume challenge, turning unstressed blood volume to stressed volume proportional to body size. In case of an increase of stroke volume index (SVI) \>15% during PLR, patients were defined as responders.
All patients were studied with no changes in anesthesia management. Measurements of SVI, GEDVI, SVV and PPV are performed before, during and after PLR. Thereafter, patients receive a fluid Bolus of 500 ml crystalloids. Again, measurements are performed before and after fluid replacement.

Passive leg raising
passive leg raising
The passive leg raising maneuver (PLR) involves a leg elevation up to 45° with the trunk in a horizontal position and is performed to induce hemodynamic effects by a volume challenge, turning unstressed blood volume to stressed volume proportional to body size.
premedication
premedication
patients receive premedication with midazolam 7.5 mg p.o.
intubation and mechanical ventilation
intubation and mechanical ventilation
After induction of anesthesia with sufentanil (0.5 µg/kg) and propofol (1.5 mg/kg), orotracheal intubation is facilitated with rocuronium (0.6 mg/kg). Anesthesia is maintained with sufentanil (1 µg/kg/h) and propofol (3 mg/kg/h) and patients are ventilated with an oxygen/air mixture in volume-controlled mode, using a tidal volume of 8 ml/kg related to the ideal body weight. Positive end-expiratory pressure is set at 5 cmH2O.
central venous catheter
central venous catheter
a central venous catheter in the right or left internal jugular vein.
arterial catheter
Continuous monitoring is performed including electrocardiogram, radial arterial pressure catheter
arterial catheter
Continuous monitoring is performed including electrocardiogram, radial arterial pressure catheter
transesophageal echocardiography
transesophageal echocardiography
Before placement of a transpulmonary thermodilution catheter a transesophageal echocardiography (TOE) is performed. TOE is used to detect diastolic dysfunction of the left ventricle and to exclude right ventricular dysfunction.
transpulmonary thermodilution catheter
transpulmonary thermodilution catheter
In presence of left ventricular dysfunction a transpulmonary thermodilution catheter is placed in the femoral artery and connected to a PiCCO2 monitor (PiCCO2, Pulsion Medical Systems, Munich, Germany).
