Fear of blood draw and total draw time combine to predict vasovagal reactions among whole blood donors

Fear of blood draws, vasovagal reactions, and retention among high school donors.

BACKGROUND We previously demonstrated that fear of having blood drawn is one of the strongest known predictors of vasovagal reactions among high school blood donors. This report examines the combined effects of donor fear and experience of vasovagal reactions on repeat donation attempts among high school blood donors. STUDY DESIGN AND METHODS Immediately after completing the blood donor healt...

Vasovagal reactions in whole blood donors at three REDS-II blood centers in Brazil.

BACKGROUND In Brazil little is known about adverse reactions during donation and the donor characteristics that may be associated with such events. Donors are offered snacks and fluids before donating and are required to consume a light meal after donation. For these reasons the frequency of reactions may be different than those observed in other countries. STUDY DESIGN AND METHODS A cross-se...

To draw or not to draw: drawing blood cultures from a potentially infected port site.

Body Mass Index as Predictor of Vasovagal Reactions in First Time Male Blood Donors

Method: All whole blood donors in Department of Transfusion medicine, Government Medical College, Thiruvananthapuram over 1 year were included in the study. Female and repeat donors were excluded. The weight and height of donors were collected from their donor registration forms. Donors who had reaction during donation and during post donation refreshment period including minor subjective feeli...

Vasovagal reactions in blood donors during or immediately after blood donation.

The aim of the study was to estimate the type, incidence and causes of donor adverse reactions during and after blood donation in a Greek Blood Bank, where medical staff is responsible for donor selection. 12 173 blood donors were studied for adverse reactions. One-hundred and seven (0.87%) donors had a vasovagal reaction during or after blood donation. Donors who gave blood occasionally had a ...
