Incidence of Vasovagal Syncope During Phlebotomy and Blood Donation

Incidence of Vasovagal Syncope During Phlebotomy and Blood Donation

Vasovagal syncope is a reaction of a body to certain triggers, such as sight of a blood and emotional trauma. The body responds by fainting secondary to overreaction. The pathophysiology is sudden drop of blood pressure and heart rate resulting in decreased blood supply to the brain and subsequent temporary loss of consciousness. Even though the frequency is low, the vasovagal reactions are seen in individuals donating blood or undergoing venipuncture at out-door patient department. The occurrence of vasovagal syncope among blood donors is usually associated with -first experience -low body weight -young age -female gender The occurrence of vasovagal reactions in outdoor patient is associated with -increased waiting time, generally more than 15 minutes -increased number of collection tubes The incidence of vasovagal reaction is comparatively higher in blood donors than those undergoing phlebotomy based on the amount of blood collected. The incidence of vasovagal syncope in both the outdoor-patient department and the blood collection centers can be reduced significantly by provision of quick services to the patients and keeping minimum equipment in individual’s sight.
