Popis: Objective To study the adverse reactions(ADRs) in blood donors after whole-blood donation in terms of frequency and types, so as to explore the predisposing factors of adverse reactions. Methods A questionnaire was designed to investigate ADRs within 2 weeks after whole blood donation. A total of 812 whole blood donors were randomly selected from September to October 2021. They were interviewed by trained medical staff before leaving the site after blood donation, then followed up by telephone 24 hours and 2 weeks after blood donation. The frequency and type of ADRs were surveyed, and the physical examination data such as gender, age, blood pressure, mean arterial pressure (MAP) and weight were collected to, analyze the predisposing factors that correlated with ADRs. Results Finally, 734 people [90.39% (734/812)], with valid demographic and physical examination information, were included in this study after on-site interviews and two follow-ups within two weeks after blood donation. The incidence of ADRs was 13.22% (97/734), of which the incidence of on-site vasovagal reactions during blood donation was 10.49% (77/734) (with the constituent ratio as 79.38%, 77/97)and the incidence of ADRs ≤ 2 weeks after leaving the blood collection site was 2.73% (20/734, including 12 donors had (1.63%, 12/734) local symptoms)(with the constituent ratio as 20.62%, 20/97). Multivariate logistic regression analysis showed that the factors influencing the occurrence of ADRs were as follows: 400mL-blood donation (OR 6.312, 95% CI 3.336-11.944), 45~60kg weight (OR 3.744, 95% CI 2.017-6.949), MAP ≤ 90 mmHg (OR 3.101, 95% CI 1.416-6.788), novel blood donor (OR 2.237, 95% CI 1.199-4.174), age of 18~30 years (OR 2.197, 95% CI1.107-4.361), female (OR 1.871, 95% CI 1.026-3.413); blood pressure, occupation, education background, body mass index (BMI) and Hb of blood donors were not the influencing factors and risk predictors of ADRs. Conclusion The application of on-site interview and two follow-ups after donation can effectively obtain the true information of blood donors′ ADRs, which can timely grasp and predict the relevant factors affecting the occurrence of ADRs, so as to take targeted preventive measures to ensure the safety of blood donors.
