Abstract : The main objective of this research project was the development of an intravenous glucose sensor which can be used to monitor and therapeutically prevent the onset of hypoglycemia in acute hemorrhagic shock. It has been shown that infusion of glucose at a rate sufficient to prevent the fall in glucose level slows or even arrests the decompensatory phase which will enhance the survival rate of wounded soldiers in battlefield settings. The extension of the compensatory phase is also of obvious utilization in civilian trauma management The goal of this project was to develop biosensor technology to better define hemorrhagic shock processes in order to optimize fluid resuscitation in trauma victims. Under this project The University of New Mexico studied a series of enzyme electrodes and biosensors, including a miniature needle-sized glucose biosensor suitable for intravenous glucose monitoring. The prototype of the biosensor developed shows a sufficient sensitivity over a wide range of linear response to glucose concentration, which covers the hypo and hyperglycemic conditions observed during the phases of hemorrhagic shock. The sensor was tested in vitro in model buffer solutions, blood plasma and whole blood, demonstrating response characteristics allowing in vivo glucose monitoring.
