Analysis of donation related vasovagal reactions in Hefei / 中国输血杂志

ABSTRACT

【Objective】 To explore the influencing factors and characteristics of blood donation-related vasovagal reactions in whole blood donation in Hefei city, and to put forward specific prevention measures. 【Methods】 Whole blood donors with vasovagal reactions related to blood donation in Hefei area from January 2021 to December 2021 were selected as the study subjects, and the related factors such as gender, age, blood donation month, initial or multiple blood donation, blood donation volume, blood donation location, and organization type of blood donation were retrospectively analyzed. 【Results】 The incidence of blood donation-related vasovagal reactions was 10.46‰ in the whole blood donation in Hefei in 2021, among which 71.89% occurred during blood collection. There were statistically significant differences in blood donation-related vasovagal reactions by blood donation age, blood donation history, blood collection month, organization type of blood donation and blood donation volume(P0.05). After balancing the age factors, there was no statistically significant difference in the incidence of DRVR between donors aged 18~22 and 23~29 years by gender(P>0.05), while there were significant differences in blood donors aged 30~39, 40~49, and 50~60 years by gender(P<0.05). Among blood donors of different ages, there were statistically different incidences of DRVR among first-time and repeated donors (P<0.05). 【Conclusion】 In the process of whole blood donation, attention should be paid to blood donors first-time, young (18~30 years old) and student, which can help prevent the occurrence of blood donation-related vasovagal reactions and better retain blood donors.
