Intraoperative fluid therapy and pulmonary complications

Area of Science:

• Anesthesiology
• Surgical Outcomes
• Critical Care Medicine

Background:

• Intraoperative fluid management is crucial for surgical patients.
• Optimizing fluid therapy can potentially reduce postoperative complications and length of stay.

Purpose of the Study:

• To investigate the association between intraoperative fluid therapy volume and postoperative pulmonary complications.
• To evaluate the impact of intraoperative fluid administration on the length of hospital stay in patients undergoing spine surgery.

Main Methods:

• Retrospective analysis of 1307 patients undergoing spine surgery.
• Assessment of administered crystalloids, colloids, and total intravenous fluids.
• Correlation analysis between fluid volumes, pulmonary complications, and length of stay.

Main Results:

• Increased crystalloid, colloid, and total fluid volumes correlated with higher odds of postoperative respiratory complications.
• A 1000 mL increase in crystalloid administration was associated with a 30% increase in complication odds.
• A total fluid volume cutoff of 4165 mL predicted pulmonary complications with 81.25% sensitivity and 71.71% specificity.
• Patients receiving >4165 mL of fluids had a significantly longer average hospital stay (3.88 days) compared to those receiving <4165 mL (2.3 days).

Conclusions:

• Higher intraoperative fluid volumes are associated with increased postoperative pulmonary complications and prolonged hospital stays in spine surgery patients.
• A threshold of 4165 mL of total intraoperative fluids may indicate increased risk.
• Further prospective trials are warranted to compare high versus low intraoperative fluid regimens.
