全血献血者离场血管迷走神经反应相关因素分析

Factors related to off-site vasovagal reaction in whole blood donors

目的探讨全血献血者发生离场血管迷走神经反应影响因素,为采取预防性策略提供依据。方法调查2019年度全血采集离场血管迷走神经反应情况,献血者性别、年龄、献血次数、体重、季节等相关因素进行分类整理与分析。结果全血400 mL捐献42 874人次中发生离场血管迷走神经反应非重度67例,重度0例,占比0.16%,单因素、多因素进行相关分析,献血者年龄(18~25岁)、体重(<55 kg)是离场血管迷走神经反应的主要影响因素;性别、献血次数、季节无统计学意义。结论我们应高度关注离场血管迷走神经反应影响因素,制定相应预防措施,减少离场血管迷走神经反应的发生,提升献血服务质量,保障献血人群安全。

Objective To explore the factors affecting the off-site vasovagal reactions in whole blood donors, aimed at providing references for formulating interventions. Methods The off-site vasovagal reactions in whole blood donors in 2019 was investigated in terms of gender, age, frequency of blood donation, weight and season were classified and analyzed. Results Among the 42 874 donors who donated 400 mL of whole blood, 67 had non-severe off-site vasovagal reaction, accounting for 0.16%, and none developed severe reaction. Single-factor and multi-factor correlation analysis showed that the age(18~25 years old) and weight(< 55 Kg) were the main influencing factors of off-site vasovagal reaction, while gender, blood donation frequency and season showed no statistical significance. Conclusion We should pay close attention to the factors predicting the off-site vasovagal reaction and formulate corresponding interventions to reduce the reaction rates, so as to improve the quality of blood donation service,and ensure the safety of blood donors.
