目的 分析葡萄糖酸钙口服液在预防单采献血不良反应特别是心血管不良反应的价值。方法 随机选取3 504例在我中心单采血小板献血者作此次研究对象,将抽取对象分为比对组(n=1 728)和探析组(n=1 776),对探析组献血者进行血小板采集前为其提供葡萄糖酸钙口服液,比对组献血者不接受任何预防措施,献血过程中对献血者进行动态血压检测及动态心电图检测。结果 对比组共发生不良反应为278例(16.08%):其中全身性不良反应无晕厥78例(4.51%);全身不良反应晕厥18例(1.04%);单采相关性的不良反应中的枸橼酸盐反应为182例(10.53%);未见溶血反应和过敏反应。探析组共发生不良反应为155例(8.72%):其中全身性不良反应无晕厥54例(3.04%);全身不良反应晕厥20例(1.12%);单采相关性的不良反应中的枸橼酸盐反应为85例(4.78%);未见溶血反应和过敏反应。探析组单采相关性的不良反应中的枸橼酸盐反应显著减少。2组差异均有统计学意义(P<0.05)。比对组与探析组中,出现血压异常48例(2.78%)和12例(0.68%);心电图异常的89例(5.15%)和32例(1.80%);心率异常112例(6.48%)和38(2.14%)。为探析组的心血管不良反应的发生率低于比对组献血者,2组差异均有统计学意义(P<0.05)。结论 在献血者单采血小板为其提供葡萄糖酸钙口服液能够有效减少心血管不良反应,降低单采血小板不良反应发生率。

目的 探讨影响初次机采血小板献血者再次捐献的相关因素,为制定机采献血者保留策略提供依据。方法 选择2016年1月1日—2016年12月31日在广州血液中心首次成功捐献机采血小板的13 899例献血者为研究对象,分析每个献血者献血时性别、年龄、文化程度、是否发生献血不良反应与下一年度是否再次捐献机采血小板的相关性。结果 男性献血者再次捐献率(10.68%)高于女性献血者再次捐献率(8.94%),差异有统计学意义(P＜0.01);献血者年龄18～25岁组再次捐献率最高为12.86%,46～60岁组再次捐献率最低为6.46%,差异有统计学意义(P＜0.001);献血者文化程度高中或职中组再次捐献率最高为11.23%,本科或以上组再次捐献率最低为8.94%,差异有统计学意义(P＜0.001);未发生不良反应献血者再次捐献率(10.37%)高于发生不良反应献血者再次捐献率(5.56%),差异有统计学意义(P＜0.01)。结论 男性、年龄较小、文化程度较低和未发生献血不良反应的献血者更愿意返回再次捐献机采血小板,对这部分献血者采取针对性保留措施,有利于建立起一支固定捐献机采血小板的献血者队伍。

Objective To explore the related factors affecting the re-donation of the first apheresis platelet donors, and to provide a basis for the retention strategy. Methods A total of 13 899 blood donors who successfully donated apheresis platelets for the first time in Guangzhou Blood Center from January 1, 2016 to December 31, 2016 were selected as subjects. The correlation among gender, age, education level, adverse reactions of blood donation and whether platelet collection was re-donated in the next year was analyzed. Results Re-donation rate of male blood donors (10.68%) was higher than that of female blood donors (8.94%). The difference was statistically significant (P<0.01). Re-donation rate of blood donors aged 18～25 was the highest 12.86%, and that of 46～60 was the lowest 6.46%. The difference was significant (P<0.001). Re-donation rate of high school or vocational college blood donors was the highest 11.23%. The lowest re-donation rate was 8.94% in the undergraduate group or above, and the difference was statistically significant (P< 0.001). The re-donation rate of donors without adverse reactions (10.37%) was higher than that of donors with adverse reactions (5.56%). The difference was statistically significant (P<0.01). Conclusion Male, younger, less educated and no adverse reactions to blood donation are more willing to return to donate platelet again. Targeting these donors for reserve measure will conducive to the establishment of a fixed platelet donor team.
