E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the effect of dobutamine on hepatic blood flow and caval & portal vein pressures during goal-directed hemodynamic therapy in patients undergoing pancreaticoduodenectomy. |
|
E.2.2 | Secondary objectives of the trial |
To assess the effects of dobutamine on systemic hemodynamics (CI, HR, SAP, DAP, MAP, CVP, SVV, PPV), systemic vascular resistance (SVR), SVRI, dPmx and portal venous resistance (PVR), cardiac index (CI), during goal-directed hemodynamic therapy in patients undergoing pancreaticoduodenectomy. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Adult ≥ 18 years ≤ 80 years (female or male). • ASA I – II – III. • Able to comprehend, sign and date the written informed consent document to participate in the clinical trial. • Patient is scheduled for pancreaticoduodenectomy (Whipple`s procedure).
|
|
E.4 | Principal exclusion criteria |
• Allergy to the medication dobutamine. • Renal insufficiency (SCr > 2 mg/dL). • Severe heart failure (EF < 25%). • Hemodynamic unstable patients. • Atrial fibrillation. • Sinustachycardia > 100 bpm on pre-operative electrocardiogram. • Sepsis. • BMI > 40. • Severe coagulopathy (INR > 2). • Thrombocytopenia (< 80 x 103 /mcL). • End stage liver disease and/or portal hypertension. • Pregnancy and breastfeeding women.

E.5 End points |
E.5.1 | Primary end point(s) |
Changes in portal and arterial HBF during goal-directed hemodynamic therapy. Changes in portal vein and caval vein pressures before and after dobutamine infusion. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
T1 - baseline measurements without inotropic support T2 - Dobutamine infusion at 2 mcg/kg/min T3 - After minimum 10 minutes, infusion will be set at 5 mcg/kg/min T4 - final hepatic blood flow will be recorded |
|
E.5.2 | Secondary end point(s) |
The evaluation of the effect of dobutamine on systemic hemodynamic measurements (CI, HR, SAP, DAP, MAP, CVP, SVV, PPV), systemic vascular resistance (SVR), SVRI, dPmx and portal venous resistance (PVR). The effect of dobutamine on hemodynamic data (HR, SAP, DAP, MAP, CI, PPV, SVV, CVP). |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
T0 – start surgery. T1 – after pancreaticoduodenectomy, at baseline without dobutamine infusion. T3 – after minimum 10 minutes of infusion of dobutamine at 2 mcg/kg/min, before raising dobutamine infusion to 5 mcg/kg/min T2 through T4 – a measurement will be made every minute (together with the hepatic blood flow measurements) T4 – before surgical reconstruction, after minimum 10 minutes of infusion of dobutamine at 5 mcg/kg/min. T5 – end of surgery.
