title: Short- and long-term renal outcomes of immediate prophylactic hemodialysis after cardiovascular catheterizations in patients with severe renal insufficiency.
abstract: BACKGROUND
  The short- and long-term effects of prophylactic hemodialysis (HD) immediately after cardiovascular catheterizations on renal function in patients with severe baseline renal insufficiency remain unknown though previous studies reported non-beneficial very-short-term effect in less severe patients.
  
  
  RESULTS
  Patients who had pre-procedural serum creatinine (Scr) between 2.5 and 5.5 mg/dl were retrospectively studied. Twenty of them (14 M/6 F, aged 69 +/- 2 years) had received prophylactic HD after radiocontrast exposure and constituted the HD group. Another 20 patients were case-matched to the baseline demographics of the HD group and served as the non-HD group. The baseline Scr were 3.9 +/- 0.2 and 3.5 +/-0.2 mg/dl, respectively (p = NS). Although the Scr at 3 months was significantly higher in the HD group (4.3 +/- 0.3 vs. 3.4 +/- 0.2 mg/dl, p = 0.02), the absolute and percentage increments from baseline to 3 months (0.4 +/- 0.2 vs. 0.0 +/- 0.2 mg/dl, p = NS, and 11 +/- 5% vs. 1 +/- 7%, p = NS, respectively) and 6 months (0.6 +/- 0.3 vs. 0.4 +/- 0.4 mg/dl, p = NS, and 18 +/- 8% vs. 8 +/- 10%, p = NS, respectively) were not statistically different. Patients who developed end-stage renal disease requiring permanent HD at 1 year were also similar in both groups (four vs. three, respectively, p = NS).
  
  
  CONCLUSIONS
  Our study confirmed that prophylactic HD immediately after contrast media administration in catheterizations failed to affect the short- and long-term renal and clinical outcomes even in patients with severe baseline renal insufficiency.
