Clinicians lack guidance on contrast-induced nephropathy (CIN) risks in critically ill patients. This review assesses limited evidence for high-risk groups, emphasizing clinical judgment for contrast media use.

Area of Science:

  • Nephrology
  • Radiology
  • Critical Care Medicine

Background:

  • Iodinated contrast media are increasingly used in critically ill patients for imaging and interventions.
  • This use presents risks for contrast-induced nephropathy (CIN), with limited clinical guidance.
  • Specific patient populations may have increased susceptibility to CIN.

Purpose of the Study:

  • To review and assess the available literature on contrast-induced nephropathy (CIN) risks.
  • To identify patient groups and clinical situations with potential increased risk for CIN.
  • To provide insights for clinicians managing contrast media administration in high-risk scenarios.

Main Methods:

  • Literature review of existing studies on contrast-induced nephropathy (CIN).

  • Analysis of evidence regarding specific patient populations (e.g., post-CABG, liver disease, renal transplant recipients).
  • Examination of risk factors such as hypotension and shock in relation to CIN.

    • Main Results:

    • Insufficient evidence links contrast media to acute renal failure post-coronary artery bypass surgery (CABG).
    • Cirrhosis may be a risk factor for renal failure in transarterial chemoembolization.
    • Evidence on CIN risk in renal transplant recipients is inconsistent; periprocedural hypotension is a potential risk factor post-PCI.

    Conclusions:

    • Clinical judgment is paramount when deciding contrast media administration in high-risk patients.
    • Adequate volume expansion is crucial, especially in emergency situations where renal status is unknown.
    • Further research is needed to clarify CIN risks in various critically ill patient cohorts.
