Haemodialysis for the Prevention of Contrast-Induced Nephropathy: Outcome of 31 Patients With Severely Impaired Renal Function, Comparison With Patients at Similar Risk and Review

Abstract

Rationale and objectives: To investigate whether haemodialysis prevents contrast-induced nephropathy (definition: increase of serum-creatinine of >or= 0.5 mg/dL within 7 days).

Materials and methods: Thirty-one patients (mean serum-creatinine 4.01 +/- 1.83 mg/dL) were dialyzed for 4.36 +/- 1.0 hours within one hour after 278.4 +/- 160.5 mL of contrast medium.

Results: Dialysis resulted in a significant reduction of serum-creatinine (2.25 +/- 1.46 mg/dL; P< 0.0001) and stable mean serum-creatinine levels 2, 3, 4, and 7 days after contrast medium and at discharge compared with baseline values. However, 19 patients (61%) developed contrast-induced nephropathy within 7 days. Four patients had to be repeatedly dialyzed. A comparison of our patients' 48 hours-incidence of contrast-induced nephropathy (9/31; 29%) versus patients at comparable risk included in seven previous studies demonstrated a prophylactic effect of dialysis only versus a subgroup in one study.

Conclusions: Data provide no hint that haemodialysis prevents contrast-induced nephropathy. Therefore, postprocedural dialysis should be restricted to patients participating in clinical studies.
