目的:分析河北省血液中心2008-2012年临床供血的动态变化及血型比例构成,探讨临床用血的规律。方法:对2008-2012年河北省血液中心各种血液发放汇总情况进行分析总结。结果:成分输血逐年提高,各种成分血的使用结构发生着改变,冷沉淀的用量逐年上升明显。洗涤红细胞和Rh(D)阴性血液用量逐年提高,临床输血更加安全、科学、合理。本中心供血范围内各血型比例稳定:B(34.26%),O(30.62%),A(25.31%),AB(9.81%)。B>O>A>AB。结论:临床用血量逐年增加,应根据临床供血的特点,制定血液的采集、制备计划,保障临床供血。
Objective: To analyze the dynamic changes of blood supply and the proportion of blood types in blood centers in Hebei Province from 2008 to 2012, and to explore the regularity of clinical use of blood. Methods: The summary of various blood distributions of blood centers in Hebei Province from 2008 to 2012 was summarized.

The amount of washed red blood cells and Rh (D) negative blood is increasing year by year, and clinical transfusion is safer, scientific and reasonable. The proportion of blood donations within the center was stable: B (34.26%), O (30.62%), A (25.31%) and AB (9.81%). B> O> A> AB. Conclusion: Clinical blood volume increased year by year, should be based on the characteristics of clinical blood supply, development of blood collection, preparation plan, to protect the clinical blood supply.
