Decreased blood pressure Intramuscular: However, dehydration is hard to examine, because there is no sound criteria for it, he added. After the procedure, the patient should be monitored for signs of lactic acidosis.
Intra-arterial contrast medium administration with first pass renal exposure. Gadolinium-based contrast media are more nephrotoxic than iodine-based contrast media in equivalent X-ray attenuating doses. Never deny a patient a clinically well- indicated enhanced MRI examination. Preparation Before intravenous iodine- or gadolinium-based contrast medium: This counts as second pass renal exposure. To reduce the risk of pulmonary adverse effects. Gadolinium-based contrast media should only be used if the indication is vital and then only intermediate or low risk agents should be used.
Contrast medium extravasation injury: Do not mix contrast media with other drugs in tubes and syringes.
Have the drugs and equipment for resuscitation readily available see 1. Patients at risk should be closely monitored by endocrinologists after iodine- based contrast medium injection. Maculopapular rashes, erythema, swelling and pruritus are most common. The majority of reactions are minor e.
Mandatory These agents should never be given in higher doses than 0.
Late adverse reactions to intravascular iodinated contrast media. Extra hemodialysis session to remove contrast agent as soon as possible after it has been administered is recommended. Hypotensive shock Respiratory arrest Cardiac arrest Convulsion. Patients at high risk.
I confirm that I am a Healthcare Professional. Discuss the need to stop nephrotoxic drugs with the referring physician.
Risk Stratification Van der Molen made sure to point out the difference in contrast agent concentration entering the kidneys is dependent on the injection site: If a hospital does this, these patients will not require special precautions. Refer to late adverse reactions section 1.
There is no additional AKI risk in patients with solitary kidneys, kidney transplants, multiple myeloma or monoclonal gammopathy. No special precautions are necessary when diabetic patients on metformin are given gadolinium-based contrast agents as the risk of PC-AKI is very low.
To reduce the risk of repeat reaction, use another contrast agent than the agent precipitating the first reaction.
Determine eGFR 48 hours after contrast medium administration.
Metformin is contraindicated and iodine-based contrast media should be avoided. Late skin reactions of the type which ghidelines after iodine-based contrast media have not been described after gadolinium-based and ultrasound contrast media.

Van der Molen answered that care in these patients starts one step before the ESUR guideline kicks in: General adverse reactions B. Powered By T3 Framework. The effect of intraarterial IA application depends on the injection site: Continue volume expansion Determine eGFR h after contrast medium. Contrast media and metformin. Gadolinium-based contrast agents attenuate X-rays well and may be misinterpreted on CT when they onn been excreted into the urinary tract. A variety of late symptoms e.
