Overview
Contrast media(CM) are widely used in diagnostic and interventional procedures with rising incidence of iatrogenic renal function impairment caused by the exposure to contrast media, a condition known as Contrast-induced nephropathy(CIN).
There are three necessary components for the definition of CIN
- Elevated serum creatinine compared to the baseline values
- Temporal relationship between the rise in serum creatinine and exposure to a contrast agent
- Exclusion of alternative explanations for renal impairment
Contrast-induced nephropathy is defined as either a greater than 25% increase of serum creatinine or an absolute increase in serum creatinine of 0.5 mg/dL that occur 48–72 hours following the exposure to CM.[1] According to a study that aimed to describe the course of creatinine rise and its determinants after exposure to contrast media, the first 24 hours post-exposure appear to be crucial in the development of CIN.[2] The same study showed that patients with less than 0.5 mg/dl rise in serum creatinine within the first 24 h were unlikely to have any clinically meaningful form of CIN.
