Vasovagal reaction is the most common type of blood donation reaction. The main cause of this reaction is the decrease of blood volume. Therefore, fluid supplement before blood donation has been proved to be effective in preventing the vagal reaction after blood donation. It was proved that isotonic (sugar & salt) drink intake before blood donation had a significant effect on reducing vasovagal reaction.~However, in 2002, WHO recommended the new reduced osmolarity rehydration formula with better taste. Oral Rehydration Salt 3 has been produced according to WHO formula with standard ingredient and easy to prepare. In addition, in Guangdong culture, sugar water is regarded as a tonic, more easily accepted. So, the aim of our study was to compare the effects of 500 ml water with Oral Rehydration Salt 3, white granulated sugar and conventional recommended water intake prior to blood donation on blood donation reaction after whole blood donation, in order to understand the effect of different liquid supplement on blood donation reaction and the willingness of blood donation again.
we compared the effect of 3 different kinds of liquids (water, Oral Rehydration Salt 3 and white granulated sugar water) intake in Vasovagal Reaction After Whole Blood Donation
