The pharmacologic properties of crystalloid, colloidal, and oxygen-carrying resuscitation fluids are described, and the findings of clinical trials of these solutions are discussed. Fluid administration is a fundamental part of resuscitation therapy. Crystalloid solutions supply water and sodium to maintain the osmotic gradient between the extravascular and intravascular compartments. ⋯ Favorable experience with inexpensive hypertonic crystalloids with improved plasma volume expansion properties may favor a return to resuscitation with crystalloid solutions. Oxygen-carrying resuscitation fluids are indicated when the patient has lost more than 25% of the total blood volume. Tailoring therapy to the individual patient and close monitoring are essential to safe and effective fluid resuscitation.
