[Nephrotoxic action of contrast media].

Contrast induced nephrotoxity [CIN] is a common form of hospital-acquire renal failure. Prevention can decrease the need for dialysis, morbility, and reduce health care costs. All patiens receiving iodine-contrast medium should be assessed for risk of developing CIN. Prophylaxis can reduce CIN. Patients at risk requiring injection of contrast medium [CM] with important clinical indications should receive a small dose of non-ionic iso-osmolar dimeric or non-ionic low osmolar monomeric CM and hydratation with normal saline before and after exposure. This brings the best protection with the fewest adverse effects.
