日前世界上血浆冷冻贮藏一般都被限制在五年左右。美国海军医院船上贮藏的冷冻血浆的有效贮期可以达到十年。这项研究是由波斯顿大学海军血液研究室完成的。其主要技术是将血浆与甘油混合后放到摄氏负80度的低温下保存。甘油的作用是能在低温下防止细胞分裂。摄氏负80度是理想温度。保持血浆质量的极限温度是摄氏负40度。血浆冷冻前要进行严格把关,检查是否有肝炎、梅毒等疾病。冷冻时,每个方形塑料袋里装上800ml血浆,同时并排放上两小瓶血浆作标本,以便将来使用时检验血浆质量情况,以防变质和产生新的疾病。使
In the world, plasma frozen storage is generally limited to about five years. The effective storage period of frozen plasma stored onboard the U.S. Navy’s hospital can reach ten years. The study was performed by the Naval Blood Laboratory at Boston University. The main technique is to mix the plasma with glycerol and store at a low temperature of minus 80 degrees Celsius. The role of glycerol is to prevent cell division at low temperatures. Celsius minus 80 degrees is the ideal temperature. The limiting temperature for maintaining plasma mass is minus 40 degrees Celsius. Before plasma freezing should be strictly checked, check whether there is hepatitis, syphilis and other diseases. When frozen, each square plastic bag fitted with 800ml of plasma, and at the same time and discharge two vials of plasma samples for future use to test the quality of the plasma to prevent deterioration and new diseases.
