Can we prevent vasovagal reactions in young inexperienced whole blood donors? A placebo controlled study comparing effects of a 330 vs 500 mL water drink prior to donation

摘要

BACKGROUND: Complications of donation reduce donor return. Younger and less experienced donors are more likely to experience vasovagal-type reactions (VVR). A water drink of approximately 500 mL shortly before donation may reduce VVR, but the effect of a smaller volume of water has not been investigated.
