title: [Non-fatal reactions to iodinated contrast media: 29 years of experience].
abstract: 178 439 cases of patients exposed to iodinated contrast media (ICM) corresponding to 137 147 to patients for excretory urography and 41 292 to cholangiography were studied. A direct interrogation making emphasis on personal antecedents of allergy to contrast media, iodinated products usage, nervous system and cardiovascular illnesses was made. Cutaneous test for iodinated contrast media was applied. If the result was positive no study with the ICM was made or it was made with special guidelines. 4302 positives and 1276 false negatives were found. 287 positive cases were premeditated and preventive medication was administered in cases of urticaria asthma/and angioedema with negative cutaneous test histories. There were no deaths registered.
