背景 已知在单采献血者中迷走神经反应(VVRs)发生率女高于男。为此,分析女性单采献血者VVR,以寻找引起高发率的可能因素。研究设计和方法 将全血献血者(WB)和单采献血者 VVR发生率与年龄和循环血量(CBV)进行比较。此外,在单采期间测量了血压和脉搏。结果 全血献血者中,男女VVR发 Background It is known that the incidence of vagal reaction (VVRs) in single-donor blood is higher in women than in men. To this end, the analysis of female single blood donor VVR, in order to find the possible causes of high incidence. The study design and methodology compared the incidence of VVR in whole blood donors (WB) and apheresis to age and circulating blood volume (CBV). In addition, blood pressure and pulse were measured during the plucking. Results Among whole blood donors, VVR was found in both men and women
