The half-life of infusion fluids: An educational review.
Almost all but the most minor surgical procedures begin with the attachment of an intravenous infusion. It is such a routine part of clinical practice that few of us give any serious thought as to which fluid to use, or what becomes of it once it is infused. However, establishing an intravenous infusion opens the door to problems such as fluid overload. Although probably rare, the incidence of this iatrogenic complication is unknown; clinicians are reluctant to report problems of their own making. A better understanding of the influence of infused fluids on the volumes of the plasma and the interstitium, and how this can change with a physiology manipulated by different aspects of clinical management, offers a more enlightened approach to fluid therapy. Through the medium of the half-life this review intends to examine what is known about the fate of infused fluids, and the factors that limit and extend their usefulness, so as to encourage an evidence-based approach to their use.
