目的:探讨青海省稀有血型红细胞深低温保存血库的建立及运行的必要性和意义。方法:将合格的Rh(D)阴性的红细胞制备为冰冻红细胞置-86℃深低温储血冰箱保存,建立青海省稀有血型红细胞深低温保存血库。结果:我们已建立了117U的稀有血型深低温保存血库,39U已应用到临床,Rh(D)阴性血液的阳性使用率由2003年的60.84%降至2007年的16.55%。结论:稀有血型红细胞深低温保存血库的建立大大降低了稀有血型血液资源浪费,提高了我省血液储备和应对公共卫生突发事件血液供应能力,对保障西宁地区、六州一地一市乃至周边省份稀有血型急救用血的及时供给具有积极的现实意义。
Objective: To explore the necessity and significance of the establishment and operation of blood bank for cryogenic cryopreservation of rare red blood cells in Qinghai Province. Methods: The qualified Rh(D)-negative red blood cells were prepared as frozen red blood cells and stored at -86°C deep cryopreservation refrigerator to establish a blood bank for cryopreservation of rare red blood cells in Qinghai Province. RESULTS: We have established a 117U rare blood cryopreservation blood bank, 39U has been used clinically, and the positive rate of Rh(D) negative blood use decreased from 60.84% in 2003 to 16.55% in 2007. Conclusion: The establishment of blood bank for cryogenic cryopreservation of rare red blood cells has greatly reduced the waste of blood resources of rare blood types, improved the blood reserves of our province and responded to public health emergency blood supply, and provided protection for Xining, six states, one city and even the surrounding areas. The timely supply of blood for emergency use of rare blood types in the province has positive and practical significance.
