When intravenous contrast is administered to the patients receiving dialysis, the technologist should employ the least amount of contrast possible for the patient's safety.
Intravenous iodinated contrast medium can be administered to patients with anuric end-stage chronic kidney disease who do not have a working transplant without increasing the risk of additional renal damage because their kidneys are no longer functional.
However, there is a theoretical possibility that administering intravascular iodinated contrast medium to an oliguric patient on dialysis could turn them into anuric patients.
Hemodialysis can effectively remove contrast media from blood (HD).
The key variables that could affect the removal of contrast media by HD are blood flow, membrane surface area, molecular size, transmembrane pressure, and dialysis time because the majority of contrast media are middle-sized molecules.
