In 1974 some 117 000 units of blood were collected by the German Red Cross Blood Center in Ulm. Some 65 000 units were distributed to hospitals, mainly as whole blood. The surplus blood units (44%) were used for the preparation of plasma products. On 1 October 1974 glass bottles were replaced by plastic blood bags. The same date was chosen for the introduction of buffycoatfree red cell concentrates. It proved possible to replace whole blood almost entirely (92% of all blood units) by red cell concentrates within a few days after the deadline. The factors which prompted the clinicians to follow this new policy are described, and the clinical and economic implications are discussed.
1974年，德国乌尔姆红十字会血液中心采集了约11.7万个单位的血液。约6.5万个单位被分发到医院，主要作为全血。剩余的血液单位（44%）用于制备血浆制品。1974年10月1日，玻璃瓶被塑料血袋取代。同一天开始引入去除白细胞的红细胞浓缩液。结果证明，在截止日期后的几天内，几乎可以完全用红细胞浓缩液替代全血（占所有血液单位的92%）。文中描述了促使临床医生采用这一新政策的因素，并讨论了其临床和经济影响。
