Previous studies using small or restricted samples suggest that vasovagal reactions to blood donation are associated with a decreased likelihood of repeat donation. In the present study, we examined data for all allogeneic whole blood donors (n=89,587) in the American Red Cross Blood Services, Central Ohio Region during an entire year. Results of a one-year follow-up revealed that moderate and severe vasovagal reactions reduced the likelihood of repeat donation by 50% or more. Light vasovagal reactions, which represented 97% of all reactions recorded, significantly reduced return rates by 20% for first-time donors and 33% for experienced donors.
以往使用小样本或受限样本的研究表明，献血时的血管迷走神经反应与再次献血可能性降低有关。在本研究中，我们检查了俄亥俄州中部地区美国红十字会血液服务中心一整年里所有异体全血捐献者（n = 89,587）的数据。一年随访结果显示，中度和重度血管迷走神经反应使再次献血的可能性降低了50%或更多。轻度血管迷走神经反应占所有记录反应的97%，首次献血者的回访率显著降低了20%，有经验的献血者降低了33%。
