[Perioperative fluid management in gastrointestinal surgery]

Area of Science:

• Surgical Oncology
• Anesthesiology
• Critical Care Medicine

Background:

• Perioperative fluid management is crucial for maintaining organ perfusion and oxygen delivery in gastrointestinal surgery.
• Fluid administration strategies significantly impact postoperative complications and mortality rates.

Purpose of the Study:

• To compare the effects of different perioperative fluid management strategies on patient outcomes in gastrointestinal surgery.
• To evaluate the benefits of restricted and goal-directed fluid management over conventional liberal fluid administration.

Main Methods:

• Systematic review of existing literature on perioperative fluid management in gastrointestinal surgery.
• Analysis of studies comparing liberal, restricted, and goal-directed fluid administration.
• Inclusion of dynamic hemodynamic monitoring parameters like cardiac output (CO), stroke volume (SV), stroke volume variation (SVV), pulse pressure variation (PPV), and pulse perfusion variation index (PVI).

Main Results:

• Restricted and goal-directed fluid management strategies demonstrate benefits over conventional liberal fluid administration.
• Individualized goal-directed fluid management, guided by hemodynamic monitoring, enhances perioperative hemodynamic stability.
• These strategies lead to improved tissue and organ perfusion, reduced complications, and shorter hospital stays.

Conclusions:

• Goal-directed fluid management, utilizing dynamic monitoring, is superior for maintaining perioperative stability and optimizing organ function.
• Clinicians must be aware of the potential risk of tissue hypoperfusion with restricted fluid management.
• Further research is needed to define optimal fluid types, timing, and volumes for perioperative care.
