Abstract: Platelet suspensions and methods for resuspending platelet concentrates are disclosed. The platelet concentrates are resuspended by combining a platelet concentrate with a substance capable of resuspending platelets, such as a salt solution. The resuspended platelets may be stored and/or administered to a patient.

Abstract: Platelet suspensions and methods for resuspending platelet concentrates are disclosed. The platelet concentrates are resuspended by combining a platelet concentrate with a hypertonic solution of either sodium chloride or potassium chloride. The resuspended platelets may be stored and/or administered to a patient.

Abstract: A blood processing method provides a red blood cell product that is free of microorganisms like Yersinia enterocolitica during storage periods over 24 hours. The red blood cell product is collected in a first container, where it is refrigerating to cool the blood product to a temperature of about 3 to 5 degrees C. The refrigerated product is transferred from the first container into a storage container through a prescribed filter medium that comprises a mass of synthetic fibers having an average fiber diameter of about 10 microns or less and a bulk density of about 0.7 gram per cubic centimeter or less. The filtered product is retained in the storage container at a temperature of about 3 to 5 degrees C. for a storage period over 24 hours after filtration. Using the filter medium, microorganisms like Yersinia enterocolitica present in the red blood cell product at the time of collection are depleted.

Abstract: The present invention relates to a stable hemoglobin based composition having sufficiently low levels of methemoglobin to effectively function as an oxygen carrying solution upon administration to a patient made by the process comprising: a) adding an oxygenated or deoxygenated form of said blood substitute to an oxygen impermeable package, and b) storing said container at from between 5.degree. C. to 45.degree. C. for sufficient time to permit the autoreduction of methemoglobin. The stable hemoglobin based composition includes hemoglobin, modified hemoglobin and/or encapsulated hemoglobin. To effectively function as an oxygen carrying solution upon administration to a patient, the stable hemoglobin based solution cannot have greater than about 50% of said hemoglobin based solution in the methemoglobin form but, preferably no more than about 15%. The invention further relates to a method to store a stable oxygen carrying solution according to the above discussed process.

Abstract: A solution for blood cell storage having sugar-containing blood cell nutrients therein and additionally containing a magnesium or calcium L-ascorbate-2-phosphate salt is taught. The magnesium and calcium L-ascorbate-2-phosphate salts remain stable below pH 7 and thus permit sterilization of the solution at a pH at which degradation of both the L-ascorbate-2-phosphate salt and the nutrient sugar present in the solution is substantially avoided.

Abstract: A solution for stabilizing red blood cells during storage contains, along with nutrients and other stabilizers, a safe and effective concentration of an inhibitor of a step of the glycolysis metabolic pathway which is subsequent to the step which forms 2,3-DPG. The inhibitor may be oxalic acid, sodium oxalate, potassium oxalate, or mixed salts thereof, for example.
