“Contrast agents are much less nephrotoxic than previously thought”, said Aart van der the current ESUR Contrast Media Safety Committee (CMSC) guideline. Renal adverse reactions to gadolinium-based contrast agents B How long should there be between two iodine-based contrast media injections for routine. The Contrast Media Safety Committee of the European Society of Urogenital Radiology is proud to present the 10th version of its Contrast Agent Guidelines.

Since our first guidelines were published, more than No special precautions are necessary when diabetic patients on metformin are given gadolinium-based contrast medium. For patients at increased risk of reaction see risk factors above. I mproving G lobal O utcomes is a global non-profit organization developing evidence-based clinical practice guidelines in kidney disease guidelines for staging acute kidney injury AKI.
Measurement of renal function B. Powered By T3 Framework. Gadolinium-based contrast medium Correlation of time of the contrast medium injection with the hemodialysis session is recommended.
Drugs and interventional devices that decrease the risk of thromboembolic complications during interventional procedures minimize the importance of the effects of contrast media. Extravascular administration of iodine-based contrast media. The validity is then only seven days. For intra-arterial contrast medium administration with first pass renal exposure hydrate the patient either with a intravenous sodium bicarbonate 1. Allergy requiring medical treatment. Extra hemodialysis session to remove contrast medium is unnecessary.
ESUR Update –
I confirm that I am a Healthcare Professional. Measurement of renal function. Contrast media and metformin. Test injection with normal saline.
Renal function assessment by questionnaire should be used if serum mwdia is not measured. Nausea, mild vomiting Urticaria Itching. All contrast media have anticoagulant properties, especially ionic agents. More severe acute reactions are rare and are similar to those after mecia and gadolinium-based agents see 1. Use a different gadolinium-based agent for previous reactors to contrast medium. The link between nephrogenic systemic fibrosis NSF and gadolinium-based contrast agents was recognized in Previous allergic reactions to barium products.
ESUR Update 2018
Determine eGFR 48 hours after contrast medium administration. Laboratory testing of renal function eGFR is not mandatory. Patients on continuous ambulatory peritoneal dialysis. Patch and delayed reading intradermal tests may be useful to confirm a late skin reaction to contrast medium and to study cross- reactivity patterns with other agents. Last update April 17, In hospital inpatietns with diagnosed AKI one to two days are preferable.
Oral hydration alone is not recommended. Refer to late adverse reactions section 1. Low- or iso-osmolar contrast media should be used for diagnostic and interventional angiographic procedures including phlebography.
Can iodine- and gadolinium-based contrast agents safely be given on the same day for routine examinations?
Time of referral B. Use non-ionic iodine-based contrast medium. Risk factors for skin reactions: To reduce the risk of an acute reaction For all patients. Risk factors for skin reactions:. However, there is no evidence that hemodialysis protects patients with impaired renal function from post contrast acute kidney injury or nephrogenic systemic fibrosis. Increased pulmonary vascular resistance. Stages 2 and 3 rarely apply in the radiology setting.
At risk contast see above. No special preparation is required.
It provides the rationale for the mediaa in this booklet. The contrast media safety committee has published 23 papers and books dealing with contrast media since its start in Gadolinium-based contrast media should only be used if the indication is vital and then only intermediate or low risk agents should be used.
History of pulmonary hypertension. Discuss the need to stop nephrotoxic drugs with the referring physician. We started in and we have on average updated the booklet every 2 to 3 years.
High osmolar ionic contrast media may induce thrombosis due to endothelial damage, particularly contrzst phlebographic procedures. Thomsen, Chairman In version 8.
The same reactions are seen after iodine- and gadolinium-based guideliness agents and after ultrasound contrast agents.
In all patients, avoid osmotic and fluid overload. Skin reactions similar in type to other drug induced eruptions.
