Abstract

Background: The quality of blood components prepared from whole blood (WB) units rapidly cooled to 20 to 24°C and stored for prolonged periods using butane-1,4-diol "cooling plates," and the factors that determine the functional activity of these cooling systems under various temperature conditions were investigated. Study Design and Methods: Validation of the cooling systems functions, performed in different environmental temperature-time schemes using WB-mock units, were recorded and analyzed in 106 temperature curves, simulating environmental conditions of blood storage at the blood drives and transport to the blood services component laboratory. The quality of red blood cells, fresh-frozen plasma, platelet concentrates, and cryoprecipitate units was studied on components routinely prepared in 2007 to 2009 from WB units collected in citrate-phosphate-dextrose-adenine or citrate-phosphate-dextrose (CPD), rapidly cooled, and stored in ambient temperature for up to 22 hours postdonation using the cooling systems. Results: Quality variables of blood components prepared from WB units rapidly cooled and held overnight for up to 22 hours postcollection, using both cooling systems, met the allowed ranges of American, European, and Israeli standards. Temperature validation of the cooling systems resulted in national standard operating procedures for the proper use in different ambient temperature ranges. Conclusion: The rapid cooling of WB and prolonged storage under different environmental conditions using cooling plate systems enabled standardization of blood storage at and transportation from all collection sites. It provided an efficient, reproducible, and cost-effective way to ensure good quality blood components, while utilizing more efficient logistic and administrative means.
