Review of the Efficacy of 7.5% NaCl/6% Dextran-70 (HSD) in Experimental Animalsand Humans

摘要

Recent years have seen a renewed interest in the use of hypertonic-hyperoncoticsolutions as plasma volume expanders for the treatment of hemorrhagic hypotension. In particular, a number of studies in experimental animals have addressed the efficacy and safety of small volume infusions of 7.5% NaCl/6% Dextran-70 (HSD). Employing models of fixed volume or fixed pressure hemorrhage, HSD has improved survival, and reversed many of the hemodynamic, hormonal, and metabolic abnormalities associated with hemorrhagic shock. In the few human field trials completed to date, HSD has been shown to be potentially beneficial in hypotensive trauma patients who require surgery or have concomitant head injury. Extensive toxicological evaluations and lack of reports of adverse effects in the human trials indicate that, at the proposed therapeutic dose of 4 ml/kg, HSD should present little risk....Hypertonic saline, Dextran-70, Hemorrhage, Resuscitation, Trauma.
