AbstractStudies were conducted to evaluate the characteristics of red cells stored for 35 days following preparation from units of whole blood anticoagulated with citrate-phosphate-dextrose-adenine-one and two (CPDA-1 and CPDA-2) and maintained at 20 to 24 degrees C for 8 hours after phlebotomy. The mean (+/- 1 SD) 24-hour survival for transfused CPDA-1 autologous red cells with hematocrit levels of 78.1 +/- 2.3 percent was 78.0 +/- 8.1 percent (n = 9). The 24-hour survival of red cells from units preserved with CPDA-2 with hematocrit levels of 79.3 +/- 4.5 percent was 74.8 +/- 8.6 percent (n = 15). This difference in survival was not significant. Red cells from control units stored for 1 day showed a 24-hour survival of 91.9 +/- 4.2 percent (n = 7). During the 8-hour holding, red cell adenosine triphosphate levels increased by 15 to 25 percent in units drawn into both CPDA-1 and CPDA-2. After the initial 8-hour period, the red cell 2,3 diphosphoglycerate levels were 54 +/- 12 percent (mean +/- 1 SD) of initial levels in units drawn into CPDA-1 and 58 +/- 8 percent of initial levels in units drawn into CPDA-2. Following 35 days of storage, units of red cells prepared from whole blood drawn into CPDA-1 and CPDA-2 had comparable plasma cation and ammonia levels and similar amounts of cell-free hemoglobin. These data indicate that red cells can be stored satisfactorily for 35 days when prepared from whole blood held at 20 to 24 degrees C for 8 hours.
