Fluid Management in Critical Care: New Insights Into Optimal Fluid Therapy

Balanced crystalloids are associated with a significant reduction in AKI incidence and RRT requirement compared to isotonic saline. Fluid restriction, particularly when combined with balanced crystalloids, improves clinical outcomes in patients with ARDS, sepsis, and heart failure. These findings support the preferential use of balanced crystalloids in critically ill patients and highlight the importance of individualized fluid management strategies in the ICU. Further research is needed to confirm these benefits and optimize fluid therapy protocols in diverse ICU populations.
