[Incidents of blood donation].

In France, more than two million blood donations are needed for transfusion each year. The rules and requirements for blood donors selection are strict and aim to protect the donors' health as well as the patients'security. However, the review of the literature shows that adverse effects of blood withdrawal occur quite frequently. They can be classified in immediate or delayed events, or local (hematoma, nerve injury, arterial puncture injury, allergy, veinitis, thrombosis) and general reactions (vasovagal reaction, citrate toxicity, cardiovascular failure, allergy to ethylene oxide, adverse effects of drugs used for some types of donation). This article reviews the principal adverse events described in the literature and concludes with the necessity to set up hemovigilance for donors, as defined in directive 2002/98/EC of the European parliament and of the council.
