Brief Summary

This study aims to compare two different methods for guiding intravenous (IV) fluid therapy in patients during their first 6 hours in the ICU after major abdominal surgery. The goal is to determine which method leads to a more optimal and precise amount of fluid administration. The objective is to compare the total fluid volumes administered when guided by Cardiac Index versus Central Venous Pressure, as well as mortality, length of stay, relaparotomy and reintubation in order to identify the more precise fluid management strategy for postoperative ICU patients.

• Blinding Strategy: NONE

Study Groups

Group A (Cardiac Index)

During the first 6 hours postoperatively in the ICU, patients will receive fluid following a Goal-Directed Fluid Therapy (GDFT) protocol, with a target Cardiac Index of 2.5 to 4.0 L/min/m².

Group Type: EXPERIMENTAL

Goal-Directed Fluid Therapy (GDFT)

Intervention Type: PROCEDURE

For the 6-hour intervention period, patients will receive fluid according to a Goal-Directed Fluid Therapy (GDFT) protocol. The treatment group will be managed to a target Cardiac Index of 2.5-4.0 L/min/m², while the control group will be managed to a target Central Venous Pressure (CVP) of 8-12 mmHg. All patients will receive a maintenance fluid volume of 25 mL/kg/24 hours, which will comprise the total volume from both parenteral fluids and enteral nutrition.

Group B (Central Venous Pressure)

During the first 6 hours postoperatively in the ICU, patients will receive fluid following a Goal-Directed Fluid Therapy (GDFT) protocol, with a target Central Venous Pressure (CVP) of 8-12 mmHg.

Group Type: ACTIVE_COMPARATOR

Goal-Directed Fluid Therapy (GDFT)

Intervention Type: PROCEDURE

For the 6-hour intervention period, patients will receive fluid according to a Goal-Directed Fluid Therapy (GDFT) protocol. The treatment group will be managed to a target Cardiac Index of 2.5-4.0 L/min/m², while the control group will be managed to a target Central Venous Pressure (CVP) of 8-12 mmHg. All patients will receive a maintenance fluid volume of 25 mL/kg/24 hours, which will comprise the total volume from both parenteral fluids and enteral nutrition.
