What is the recommendation regarding the use of estimated glomerular filtration rate (GFR) in the setting of renal dysfunction?
It is recommended that estimated GFR should be calculated as close to the day of the procedure as possible and should be documented in the medical record, ideally as part of the preprocedural checklist. The risk of contrast-induced renal injury increases with increasing volume of contrast administered, and physicians should follow a principal of as low as reasonably possible, especially in patients who have preexisting renal dysfunction. Furthermore, current guidelines recommend use of preprocedural hydration in patients who have a reduced GFR.
