PURPOSE OF REVIEW: To highlight some of the recent key issues surrounding crystalloid and colloid fluid management of critically ill patients. RECENT FINDINGS: Significant developments have been made in the understanding of ionic balance of fluids and their effects on acid-base, the role of hydration and overhydration, alkalinization of fluids in patients at high risk for contrast induced nephropathy, and finally the role of colloids in acute kidney injury. SUMMARY: Despite hydration remaining a key principle in fluid management in many patients, volume overload is of considerable concern. Recent evidence also suggests that balanced electrolyte formulations are preferable to saline-based formulations in a variety of clinical settings. Furthermore, alkalinization of fluids is protective in the setting of contrast-induced nephropathy. Oncotic load appears to be the most important factor in acute kidney injury associated with colloid fluid therapy.
