Two animal studies demonstrated positive results in rat models of early burn resuscitation with diaspirin cross-linked hemoglobin versus conventional burn resuscitation strategies [ 1718 ]. Unmodified cell-free haemoglobin is not useful as a blood substitute because its oxygen affinity is too high for effective tissue oxygenation, the half-life within the intravascular space that is too short to be clinically useful, it has a tendency to undergo dissociation in dimers with resultant kidney damage and toxicity, and because free haemoglobin tends to take up nitric oxide, causing vasoconstriction.approve the use of a blood substitute – a product called Hemopure.
