[Preventing fainting due to needles or blood].
A 29-year-old medical student suffered from vasovagal syncope triggered by blood and blood-related procedures, such as injections and injuries. Fainting was preceded by prodromal symptoms like light-headedness and altered vision. The patient consulted the Syncope Unit at the Academic Medical Centre, Amsterdam, the Netherlands, and received instructions on how to apply counterpressure manoeuvres. He was also successfully treated with psychological deconditioning, which consisted of desensitisation through exposure in vivo and cognitive behavioural therapy. Emotionally triggered vasovagal syncope is predominantly seen in young people and can lead to serious complications. It can be treated with simple interventions like drinking water and performing counterpressure manoeuvres. Psychological deconditioning is an effective additional therapy.
