In an effort to meet the increasing demands for blood to cover routine surgery and in order to reduce the amount of time-expired blood, we have adopted a system of grouping and screening patients' blood preoperatively but not crossmatching blood unless there is more than a 30 per cent chance that it will be used. This approach is based on schemes developed in the USA over the past three decades. If there is unexpected haemorrhage at operation and the patient's serum is known to be free of irregular antibodies, blood of the same ABO group is provided, with only an abbreviated crossmatch to check ABO compatibility. During the first 6 months in which the new scheme was in operation it is estimated that the laboratory crossmatched at least 3000 units of blood (44 per cent) less than it would otherwise have done. 336 units were transfused after an abbreviated crossmatch and, as expected, there were no haemolytic transfusion reactions.
为了满足常规手术对血液日益增长的需求，并减少过期血液的数量，我们采用了一种术前对患者血液进行分组和筛查的系统，但除非有超过30%的使用可能性，否则不进行交叉配血。这种方法是基于美国在过去三十年中制定的方案。如果手术中出现意外出血，且已知患者血清中没有不规则抗体，则提供相同ABO血型的血液，仅进行简略交叉配血以检查ABO血型相容性。在新方案实施的前6个月，据估计实验室交叉配血的血液单位至少比原本少3000单位（44%）。336单位血液在进行简略交叉配血后进行了输血，正如预期的那样，没有发生溶血性输血反应。
