Patients who are receiving dye should be warned that they may feel a sensation of warmth following the injection; warmth in the groin area may make them feel as though they have been incontinent of urine. Nausea, diaphoresis, itching, or difficulty breathing may indicate allergy to the dye and should be reported immediately to the physician or nurse practitioner. Sedation may be required for patients who are agitated or disoriented. Patients who are in pain may require pain medication before the examination. The patient should be questioned about any allergies to contrast material, iodine, or shellfish. The BUN and creatinine levels should be checked before administration of contrast material because it is excreted through the kidneys. Patients with elevated BUN and creatinine or known renal disease may be unable to tolerate the contrast material.
