Methods and Treatment of Trauma

1 .- 21 . (canceled)

22 . A method for reducing a level of blood urea nitrogen (BUN) in a trauma patient in need thereof comprising administering stored oxygen reduced blood to the trauma patient in need thereof, the stored oxygen reduced blood comprising a blood product having a reduced oxygen saturation level prior to and during storage, wherein the trauma patient in need thereof has kidney injury or kidney damage, wherein the trauma patient in need thereof has an elevated level of BUN prior to the administering, and wherein the level of BUN is reduced independently by at least 5% in the trauma patient in need thereof after the administering as compared to a trauma patient administered non-oxygen reduced blood stored under conventional conditions.

23 . The method of claim 22 , wherein the trauma patient in need thereof is a hemorrhagic trauma patient.

24 . The method of claim 23 , wherein the hemorrhagic trauma patient has trauma selected from the group consisting of surgery, a penetrating wound, blunt force trauma, injury due to a fall, and injury due to a car accident.

25 . The method of claim 22 , wherein the stored oxygen reduced blood has an oxygen saturation (SO 2 ) level of 20% or less prior to and during storage.

26 . The method of claim 22 , wherein the stored oxygen reduced blood is stored for a period of up to 28 days prior to the administering.

27 . The method of claim 22 , wherein the stored oxygen reduced blood is stored for a period of up to 42 days prior to the administering.

28 . The method of claim 22 , wherein the stored oxygen reduced blood is stored oxygen and carbon dioxide reduced blood.

29 . The method of claim 28 , wherein the stored oxygen and carbon dioxide reduced blood has an oxygen saturation (SO 2 ) level of 20% or less and a partial pressure of CO 2 (pCO 2 ) of between 10 and 30 millimeters of mercury (mmHg) prior to and during storage.

30 . The method of claim 22 , wherein the level of BUN is reduced by at least 10% in the trauma patient in need thereof after the administering as compared to a trauma patient administered non-oxygen reduced blood stored under conventional conditions.

31 . The method of claim 30 , wherein the level of BUN is reduced by at least 20% in the trauma patient in need thereof after the administering as compared to a trauma patient administered non-oxygen reduced blood stored under conventional conditions.

32 . The method of claim 31 , wherein the level of BUN is reduced by at least 50% in the trauma patient in need thereof after the administering as compared to a trauma patient administered non-oxygen reduced blood stored under conventional conditions.

33 . The method of claim 22 , wherein the trauma patient in need thereof has one or more preexisting or underlying conditions selected from the group consisting of diabetes, ischemic heart disease, systemic inflammatory syndrome brought on by trauma or infection, multiple organ failure brought on by trauma or infection, smoke inhalation, chronic pulmonary obstructive disease such as systemic inflammation due to infection, a coagulopathy disorder, and an autoimmune disease.

34 . The method of claim 33 , wherein the trauma patient has two of the preexisting or underlying conditions.

35 . The method of claim 22 , wherein the stored oxygen reduced blood comprises an anticoagulant.

36 . The method of claim 22 , wherein the stored oxygen reduced blood comprises an additive solution.

37 . The method of claim 36 , wherein the additive solution is selected from the group consisting of additive solution 1 (AS-1), additive solution 3 (AS-3), additive solution 5 (AS-5), saline-adenine-glucose-mannitol (SAGM), phosphate-adenine-glucose-guanosine-saline-mannitol (PAGG-SM), phosphate-adenine-glucose-guanosine-gluconate-mannitol (PAGG-GM), mannitol-adenine-phosphate (MAP), additive solution 7 (AS-7), erythrosol-5 (ESOL-5), experimental additive solution 61 (EAS61), oxygen free additive solution 1 (OFAS1), oxygen free additive solution 3 (OFAS3), and any combination thereof.

38 . The method of claim 22 , wherein the blood product having a reduced oxygen saturation level is selected from the group consisting of oxygen reduced whole blood, oxygen reduced leukoreduced red blood cells, oxygen reduced and platelet reduced red blood cells, oxygen-and platelet-reduced leukoreduced red blood cells, oxygen reduced packed red blood cells, oxygen reduced platelet reduced packed red blood cells, oxygen reduced leukoreduced packed red blood cells, and oxygen-and platelet-reduced, leukoreduced packed red blood cells.

39 . The method of claim 22 , wherein the stored oxygen reduced blood has an oxygen saturation (SO 2 ) level of 10% or less prior to and during storage.

40 . The method of claim 22 , wherein the stored oxygen reduced blood has an oxygen saturation (SO 2 ) level of 5% or less prior to and during storage.

41 . The method of claim 22 , wherein the administering maintains the BUN level in the trauma patient in need thereof below 100 milligrams per deciliter (mg/dL), thereby preserving kidney function in the trauma patient in need thereof.
