Aim of study: The renal impact of repeated iodinated contrast exposure in critically ill patients with pre-existing renal impairment
Methods: A prospective observational cohort study included 112 critically ill patients admitted to the intensive care units of Cairo University hospitals with baseline estimated glomerular filtration rate (eGFR) <90 mL/min/1.73 m² who underwent one or two intravascular iodinated contrast administrations. Hemodynamically unstable patients were excluded. Patients were systematically followed to evaluate both short- and long-term renal outcomes. Serum creatinine, eGFR, urine output, contrast-associated acute kidney injury (CA-AKI), chronic kidney disease (CKD) progression and dialysis requirement were assessed after each exposure and during 6 months follow-up. Logistic regression analysis was performed.
Inclusion Criteria:
Exclusion Criteria:
patients who underwent a single contrast exposure with impaired kidney function.
Patients who received two contrast administrations with impaired kidney function.
