Purpose Lyophilized plasma LP is a light weight powder that remains stable for a prolonged period of time and in a broad range of temperatures. The powder is rapidly reconstituted into a product that preserves coagulation factor activity and suppresses harmful inflammation. The purpose of this project was to demonstrate that LP could be optimized by minimizing the reconstitution fluid and improving the constituents. Scope Specific aim 1 focused on determining the minimum amount of fluid required to reconstitute a safe and effective product. Specific aim 2 evaluate four fluid options for reconstitution. Specific aim 3 evaluated the concentration of ascorbic acid used to buffer the LP and potentially reduce the amount of inflammation due to injury. Finally, specific aim 4 involved development of a survival model that utilized the final optimized LP product. Findings LP can be safely reconstituted with 50 of the original volume with sterile water being the best fluid for reconstitution. Ascorbic acid can safely be used to buffer the LP, and the concentration does not make a difference.
