Goal-directed fluid restriction during brain surgery: a prospective randomized controlled trial

Area of Science:

• Neurosurgery
• Critical Care Medicine
• Fluid Management

Background:

• Brain swelling is a significant concern in neurosurgical patients.
• The efficacy of goal-directed fluid therapy in this population remains unclear.

Purpose of the Study:

• To evaluate the impact of intraoperative goal-directed fluid restriction (GDFR) on postoperative outcomes.
• Assessing the effect of GDFR on high-risk patients undergoing brain surgery.

Main Methods:

• Randomized controlled trial comparing GDFR with usual care in high-risk neurosurgical patients.
• GDFR involved restricted fluid maintenance (3 ml/kg/h crystalloid) and selective colloid boluses.
• Primary outcome was ICU length of stay; secondary outcomes included complications, hospital stay, and mortality.

Main Results:

• The GDFR group received significantly less colloid and crystalloid intraoperatively.
• ICU length of stay was shorter (3 vs. 6 days) and ICU costs were lower in the GDFR group.
• The GDFR group experienced fewer postoperative complications (19.2% vs. 34.7%).

Conclusions:

• Intraoperative GDFR in high-risk neurosurgical patients reduces ICU length of stay and costs.
• GDFR is associated with decreased postoperative morbidity in this patient cohort.
• Further research may explore long-term effects and broader applicability.
