In patients with septic shock, the administration of fluids during initial hemodynamic resuscitation remains a major therapeutic challenge. We are faced with many open questions regarding the type, dose, and timing of intravenous fluid administration.
There are only four major indications for intravenous fluid administration: aside from resuscitation, intravenous fluids have many other uses including maintenance and replacement of total body water and electrolytes, as carriers for medications, and for parenteral nutrition.
In this lecture, the different fluid management strategies are discussed including early adequate goal-directed fluid management, late conservative fluid management, and late goal-directed fluid removal.
In addition, the concept of the "four D’s" of fluid therapy is introduced, namely drug, dosing, duration, and de-escalation.
During the treatment of patients with septic shock, four phases of fluid therapy should be considered in order to provide answers to four basic questions. These four phases are the resuscitation phase, the optimization phase, the stabilization phase, and the evacuation phase.
The four questions are “When to start intravenous fluids?”, “When to stop intravenous fluids?”, “When to start de-resuscitation or active fluid removal?” and finally “When to stop de-resuscitation?”.
In analogy to the way we handle antibiotics in critically ill patients, it is time for fluid stewardship.
