Il faut prémédiquer les allergiques avant un examen d’imagerie avec produit de contraste : contre

Abstract

Anaphylactic reactions due to iodinated contrast media (ICM) are rare and they occur more frequently with ionic ICM compared with non-ionic ICM. These reactions are more frequent in asthmatic patients, whereas no study is actually available, which would allow us to determine if this risk is greater in allergic subjects. The efficacy of premedication for the prevention of an anaphylactic reaction before injection of an ICM has not been demonstrated in unselected patients, asthmatic patients or allergic patients. Only the use of non-ionic ICMs reduces the risk of an anaphylactic reaction in asthmatics.
