Abstract:
:Blood was drawn from volunteer donors and frozen using the high glycerin, mechanical freezing procedure accepted by the United States Navy. Subsequently, the units of blood were thawed and washed. Various anticoagulants were added, and the red cells were stored in a refrigerator at 4 degrees C for periods of up to 28 days. Chemical analyses were performed periodically. These showed that the addition of the anticoagulants ACD, CPD and CPDA-1 caused the red cells to be preserved better than the currently accepted 0.9-percent NaCl, 0.2-percent glucose solution. In vivo 51Cr viability studies performed on blood stored with CPDA-1 for 14 days showed a 24-hour viability of 78.8 +/- 8.4 percent. In a subsequent study, the blood was stored for 21 days prior to freezing and then was rejuvenated and frozen. The cells were thawed, washed, and stored at 4 degrees C with CPDA-1 for an additional 14 days. The 24-hour viability of these cells was determined to be 74.0 +/- 5.1 percent. These findings show that the postthaw storage time of red cells can be increased greatly over the now-accepted 24 hours, if bacterial sterility can be assured.
