Zusammenfassung: | Background
All studies of vasovagal syncope (VVS) after blood donation have been performed with civilian donors. We hypothesized that military donors have a lower incidence of VVS and a particular set of predisposing factors.
Study Design and Methods
Retrospective case–control study matching every case of VVS seen from 2011 to 2019 with two controls without VVS from the same blood drive. We used the odds ratio (OR) and its 95% confidence interval (CI), estimated by multivariate logistic regression, to identify independent predictors of VVS.
Results
There were 105 episodes of VVS among 65.481 whole blood donations (0.15%). VVS was more frequent among donors from military academies than from other military units (0.37% vs. 0.10%, p |
