Plasma expanders. An update.
This review of the literature has revealed that isotonic fluids, such as 0.9 percent sodium chloride and Ringer's lactate, are effective plasma volume expanders. Despite the continued use of a variety of colloid solutions in resuscitation, there is no good evidence to document a benefit of these solutions over the crystalloid solutions. The additional cost of colloid compared with crystalloid is another argument against colloid use. The most interesting solution currently being assessed is hypertonic saline solution. Its major benefit is that a small volume of fluid can achieve effective resuscitation. The smaller weight gain and lower incidence of peripheral edema may also prove to be significant benefits. Further evaluations are needed to verify the efficacy of this therapy. Finally, a recent National Institute of Health consensus panel identified the appropriate indications for fresh frozen plasma. They concluded that there is no indication for the use of fresh frozen plasma as a volume expander.
