Restrictive and liberal fluid administration in major abdominal surgery

Area of Science:

• Anesthesiology and Perioperative Medicine
• Surgical Critical Care
• Fluid Management Strategies

Background:

• Optimizing perioperative fluid administration is crucial for patient safety during major abdominal surgery.
• Previous studies have yielded conflicting results regarding the optimal fluid management approach.
• Understanding the specific impact of fluid restriction on postoperative complications is essential for clinical practice.

Purpose of the Study:

• To evaluate the efficacy of a restrictive perioperative fluid administration strategy in reducing postoperative complications in adults undergoing major abdominal surgery.
• To compare the incidence of infectious, pulmonary, cardiac, gastrointestinal, and renal complications, as well as mortality, between restrictive and liberal fluid administration groups.

Main Methods:

• A systematic literature search was conducted across multiple databases (MEDLINE, EMBASE, Cochrane) and reference lists up to December 2015.
• Randomized controlled trials (RCTs) assessing fluid therapy and morbidity/mortality in major abdominal surgery patients were included.
• A meta-analysis of ten RCTs involving 1160 patients was performed using Review Manager software, with trial quality assessed by the Jadad scoring system.

Main Results:

• Perioperative restrictive fluid therapy significantly reduced the risk of postoperative infectious complications (OR=0.54, 95% CI: 0.39-0.74).
• A significant reduction was also observed in pulmonary (OR=0.49, 95% CI: 0.26-0.93) and cardiac complications (OR=0.45, 95% CI: 0.29-0.69).
• No significant effect was found on gastrointestinal or renal complications, or postoperative mortality.

Conclusions:

• Perioperative restrictive fluid administration is superior to liberal fluid administration in mitigating infectious, pulmonary, and cardiac complications following major abdominal surgeries.
• This approach may lead to improved patient recovery and reduced healthcare burden.
• Further research could explore long-term outcomes and specific patient subgroups.
