Risk factor analysis of plasma donation related vasovagal reaction
Journal Title: Chinese Journal of Blood Transfusion - Year 2022, Vol 35, Issue 6
Abstract
Objective To investigate the risk factors of vasovagal reactions(VVR) related to plasma donation, so as to put forward clinical suggestions for early identification and accurate intervention of high-risk groups to ensure the safety of plasma donation. Methods The demographic characteristics(i.e. gender, age, weight) and records of plasma donors(donation history, pulse before plasma donation, duration of collection, etc.) were collected from July to December 2019 in a region of Sichuan. Based on logistic regression analysis, the correlation between these factors and the risk of VVR was explored. Results The information of 69 172 donors was collected, and the incidence of VVR was 7.04‰. The risk of VVR was reduced by 99% in the group with plasma collection duration less than 30 minutes compared with the group with plasma collection duration more than 50 minutes(OR, 0.01; 95% CI, 0.00~0.01; P<0.001). The risk of male group was 94 % lower than that of female group(OR, 0.06; 95% CI, 0.04~0.10; P<0.001). Compared with the 45~50 kg group, the risk of weight greater than 80 kg group decreased by 80%(OR, 0.20; 95% CI, 0.09~0.42; P<0.001). The risk of repeated donation group was 34 % lower than that of the first time donation group(OR, 0.66; 95% CI, 0.47~0.91; P<0.001). The risk of VVR in the group with pulse greater than 90 bpm before plasma donation was 2.43 times that in the 60~69 bmp group(OR, 2.43; 95% CI, 1.75~3.36; P<0.001). Conclusion Duration of plasma collection, gender, weight, frequency of plasma donation, pulse before plasma donation and donor status are independent risk factors for plasma donation-related VVR. Among them, plasma collection duration, gender and weight were the main independent risk factors for plasma donation-related VVR. For donors with plasma collection duration more than 50 minutes, female and low weight, higher risk of VVR was presented and more preventive intervention should be given.
