Personalizezed Hemodynamic Optimization Using Stroke Volume, Pulse Pressure Variation, and Continuous Cardiac Index...

Area of Science:

• Anesthesiology
• Hepatobiliary Surgery
• Critical Care Medicine

Background:

• Major hepatic resections involve significant fluid shifts and bleeding risks.
• Optimizing perioperative fluid management is crucial for patient safety and outcomes.
• Current fluid administration strategies may not be personalized enough for complex surgeries.

Purpose of the Study:

• To evaluate the impact of personalized goal-directed hemodynamic therapy (GDHT) on fluid administration and intraoperative bleeding.
• To compare GDHT guided by radial artery pulse contour analysis with conventional care in major liver resection patients.

Main Methods:

• Prospective, randomized, parallel-group trial involving adult patients undergoing major hepatic resection.
• Intervention group received GDHT using ProAQT™ monitor, guided by stroke volume, pulse pressure variation (SVV, PPV), and cardiac index (CI).
• Control group received conventional perioperative care.

Main Results:

• The GDHT group experienced significantly less blood loss (292.63 ± 274.06 ml) compared to the control group (728.13 ± 618.59 ml) (p = 0.009).
• Fewer patients in the GDHT group required intraoperative blood transfusions (p = 0.005).
• Total intraoperative fluid infusion was significantly lower in the GDHT group (1125.79 ± 751.2 ml) versus the control group (2853.13 ± 1432.18 ml) (p = 0.001).

Conclusions:

• Personalized goal-directed therapy effectively optimizes intraoperative fluid administration during major liver resections.
• GDHT significantly reduces intraoperative bleeding and the need for blood transfusions in this patient population.
• Radial artery pulse contour analysis is a valuable tool for guiding hemodynamic management in hepatic surgery.
