摘要
目的:探讨年龄因素对临床血小板输注所产生的影响。方法:对72例需要输注血小板的患者做输注前及输注后24h外周血血小板计数,计算血小板增加修正值以评价输注效果。结果:年龄≤30岁、>30～≤50岁、>50～≤70岁、>70岁的4组患者血小板输注无效率分别为19.0%、43.6%、60.3%、41.7%;50岁以上患者中部分输注前血小板计数值较高,而其输注后的血小板增加量并不明显。结论:总体上血小板输注无效率随年龄的增加而增加,部分原因是大龄患者在血小板计数较高时就进行输注,反而效果不明显。
Objective：To investigate the influence of patients＇ age on the effect of platelets transfusion.Method：Peripheral blood platelets of 72 patients required platelet transfusion were counted 24 hours before and after each infusion.Corrected count increment was calculated to evaluate the effect of platelet transfusion.Result：The platelet transfusion refractoriness（PTR）rate of each group was 19.0%（age≤30）,43.6%（age 31 to 50）,60.3%（age 51 to 70）and 41.7%（age〉70）.And platelet level before infusion of some patients over 50 years old was found to be higher than the average while the corresponding post-transfusion platelet increments were not obvious as others.Conclusion：The occurrence of PTR is generally increased with age,partially because platelet transfusion is carried out for elderly patients when their platelets are still at a high level.
