| Abstract
Background and Objectives
Although almost all blood donors experience none or minimal complications during blood donation, sometimes adverse reactions may occur. Vasovagal shock is one of the well-known post donation experiences. The aim of this study was to determine factors influencing this complication during blood donation.
Materials and Methods
This is a sectional study on blood donors in Isfahan Blood Transfusion Center through 2006. Patients were examined and consulted for any contraindications before donation attempt. Age, sex, BMI, and previous history of blood donation were compared between the two groups of “normal donors” and “those with vasovagal reactions”. Data were analyzed using SPSS.
Results
Out of all blood donors, 5180 (98%) had no complications while 105 (2%) experienced vasovagal reactions (p<0.001) 8.6% of women and 1.8% of men suffered from the faint episode (p<0.05). This reaction was more frequently observed among first time donors (5.6%) compared with the others.
Conclusions
Vasovagal reaction is more common in donors with low body weight, younger donors, females, and first time donors. Body mass index and sleep factor did not have any tangible effect on vasovagal reaction. Pallor and perspiration are common while unconsciousness and seizure are rare. Careful selection and evaluation of blood donors by experienced physicians or trained nurses play an important role in prevention of adverse reactions.
