It Should be Noted in Patients with Renal Dysfunction before Angiography

When patients with renal insufficiency during contrast agent checks to pay special attention to prevent contrast-induced nephropathy. Contrast-induced nephropathy refers to within 24 to 72 hours after angiography significantly elevated serum creatinine of a disease. Patients with renal insufficiency are more prone than normal contrast-induced nephropathy, renal insufficiency, so patients before angiography should be noted that during the following six points.

1. Renal insufficiency and diabetes, heart failure, high blood pressure are more likely to occur in patients with contrast-induced nephropathy, so be sure to check before making the contrast of these history to tell the doctor, and accept the relevant examination.

2. Patients with renal insufficiency prior to angiography should disable non-steroidal anti-inflammatory drugs, angiotensin converting enzyme inhibitors and angiotensin Ⅱ receptor blockers and other drugs; discontinuation of metformin in patients with diabetes.

3. Angiography in patients with renal insufficiency, 24 hours ago disable diuretics and fluid under the guidance of doctors.

4. Patients with renal insufficiency to make use of low osmolar contrast media or isotonic contrast agent, and the use of the minimum effective dose.

5. Patients with renal insufficiency between two angiography, at least more than one week interval.

6. If you can use other tests instead of angiography in patients with renal insufficiency, the best choice for an alternative to other methods, such as CO2 angiography or magnetic resonance angiography. If you must conduct angiography angiography after dialysis treatment can help clear the blood contrast agents.
