With the increasing safety of allogeneic blood supply and declining need for transfusion due to patient blood management, the practice of preoperative autologous donation (PAD) continues to decline. The practice gained popularity during the 1980s and 1990s with the emergence of transfusion-transmitted human immunodeficiency virus and hepatitis C. At the peak of this public concern, the National Marrow Donor Program recommended that marrow donors have 1 to 3 autologous units of blood collected before their marrow harvest to minimize the likelihood of allogeneic transfusion. After three decades, the practice remains prevalent in marrow donors. We aimed to study the efficacy of PAD in healthy marrow donors.
PADs performed before marrow harvest in healthy donors at our center between January 2013 and July 2015 were reviewed. The utilization of autologous units and decrease in hemoglobin levels due to PAD and marrow harvest were studied. Similar practices were assessed in the rest of the United States through a brief survey.
Of a total of 262 autologous units collected from 136 donors, 25.2% were wasted. Ninety-nine percent of the marrow donors received at least 1 unit of blood irrespective of the need. PAD contributed to preoperative anemia, exposing three donors to allogeneic blood transfusion. The survey results showed a mixed response with some institutions continuing and others not practicing PAD.
PADs are not justified in healthy marrow donors as they expose them to a risk of preoperative anemia and hence a greater risk of transfusion.
随着异体输血安全性的提高以及患者血液管理使输血需求减少,术前自体献血(PAD)的做法持续减少。在20世纪80年代和90年代,随着输血传播的人类免疫缺陷病毒和丙型肝炎的出现,这种做法开始流行。在公众关注度达到顶峰时,国家骨髓捐赠计划建议骨髓捐赠者在采集骨髓前采集1至3个自体血单位,以尽量减少异体输血的可能性。三十年后,这种做法在骨髓捐赠者中仍然普遍。我们旨在研究PAD在健康骨髓捐赠者中的效果。
回顾了2013年1月至2015年7月在我们中心健康捐赠者进行骨髓采集前的PAD情况。研究了自体血单位的使用情况以及PAD和骨髓采集导致的血红蛋白水平下降情况。通过简短调查评估了美国其他地区的类似做法。
从136名捐赠者中总共采集了262个自体血单位,其中25.2%被浪费。99%的骨髓捐赠者无论是否需要都接受了至少1个单位的血液。PAD导致术前贫血,使3名捐赠者接受了异体输血。调查结果显示反应不一,一些机构继续采用,而另一些机构则不再实行PAD。
PAD对健康骨髓捐赠者不合理,因为这会使他们面临术前贫血的风险,从而增加输血风险。
