“…The incidence was significantly higher for donors aged 16 to 29 than for donors who are older for both sexes and all donation types 12 . In our study Female donors had a statistically significant higher rate of VVR, which supports findings of previous studies [13][14][15] . On the other hand many other authors reported that there is no significant difference between men and women donors for VVR [16][17][18] .…”

“…More than 150 000 people experience syncope or nearsyncope each year at the time of blood donation to the American Red Cross. 5 Reducing such syncopal reactions could have a beneficial impact on donor convenience, safety, and desire to donate again. Currently, in blood donation facilities, the major preventive strategies against syncope focus on postdonation food and beverage, with little emphasis on predonation factors, such as water drinking.…”

“…Varios autores coinciden en que la edad menor de Diversos factores relacionados con la experiencia 25 a 30 años y la donación por primera vez son de la donación influyen en el retorno de donantes a factores de riesgo para la presencia de efectos indeseables a la donación (1,2,(6)(7)(8). Esta situación podría explicarse porque usualmente la primera donación se efectúa a más temprana edad; además, las personas jóvenes tienen sensibilidad barorreceptora ventncular más baja que los individuos mayores, quienes suelen ser hemodinámicamente más estables (1).…”

“…El sexo femenino fue un factor de predisposición a la reacción vasovagal, a diferencia de lo registrado en otros estudios (1,6,7). Una posible explicación puede ser el peso corporal menor en el sexo femenino con relación al sexo masculino (cuadro l), con la consiguiente hipovolemia, secundaria al mayorvolumen de sangre perdido, en donantes de más baja estatura.…”
