“…In 2001, Newman et al also found a high number (46%) of subjects with tonic and myoclonic or twitching muscle activity after vasovagal responses during blood donation [22]. Though the number of blood donations increases until 50 years of age, the number of syncopal reaction rates was highest in patients under 40 years of age [22].…”

“…Pre-syncope reactions (no loss of consciousness) and syncope reactions (loss of consciousness) decreased blood donor return rates by 29-37% and 58-78%, respectively, in comparison to donors who did not have a vasovagal reaction [15,37,38,40]. Syncope occurs in approximately 4-5% of vasovagal reactions [1] and in 0.12-0.27% [1,21,42] of allogeneic whole blood donations. 60-73% of the syncope reactions occur after the donor leaves the bed due to gravity, and 10-12% of the reactions occur after the donor leaves the blood collection site [41,42].…”

Studies show that women, and especially smaller women, are more susceptible to gravity-precipitated syncope, and almost all syncope reactions that occurred after leaving the blood collection site occurred in women [41].…”

The emphasis on high-school blood drives and acceptance of 16-year-old blood donors led to more research on physiologic and psychological ways to decrease vasovagal reaction rates in young blood donors and to increase donor retention. Research on how to accomplish this has been advantageous for the blood collection industry and blood donors. This review discussed the current situation and what can be done psychologically, physiologically, and via process improvements to decrease vasovagal reaction rates and increase donor retention. The donation process can be significantly improved. Future interventions may include more dietary salt, a shorter muscle tension program to make it more feasible, recommendations for post-donation muscle tension / squatting / laying down for lightheadedness, more donor education by the staff at the collection site, more staff attention to donors with fear or higher risk for a vasovagal reaction (e.g. estimated blood volume near 3.5 l, first-time donor), and a more focused donation process to ensure a pleasant and safer procedure.

, Data was collected from eight dental hospitals in four provinces of Pakistan. Attendants of the patients admitted in the surgical ward with age more than 16 years were included. Knowledge and practices of the participants were evaluated through a selfadministered questionnaire .Ethical consent was obtained from the ethical committee or concerned authority of all eight hospitals. Results:Response rate was 84 %. In total 55% male and 45 % female participated with 15.5% of the total sample population was under the age of 20 years. The age group with the maximum number of participant was between 20 to 39 years of age. 26% and 22.5% of the males and female participants respectively had knowledge . About blood donation, lesser percentage of attendants, 7.2% of the males and 4.6% declared that they had donated blood in the past. Based on education levels, it was highest among graduates (3.5%) and less in primary educated (2.2%) and uneducated respondents was 0.7%. 18% of the males and 17% females asserted that they hold some kind of fear of blood donation. Conclusion:The population is not adequately knowledgeable regarding blood donation. There is a need for proper campaign to educate masses at national level within Pakistan to promote more people to become regular volunteers.
