NCT00175227
First received: September 10, 2005
Last updated: May 9, 2011
Last verified: May 2011
  Purpose

Patients with pre-existing kidney disease are at high risk of acute renal failure when exposed to radio-contrast dyes, for example during a cardiac angiogram.

The investigators hypothesize that an infusion of saline + furosemide + mannitol will reduce rates of contrast-induced nephropathy when compared with saline infusion controls.

Primary Outcome Measures:
  • Proportion of patients that develop contrast-induced nephropathy after cardiac angiography [ Time Frame: Within 48 hours of angiogram ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety of the intervention based on transfer to ICU, need for dialysis, or death [ Time Frame: During hospitalization episode ] [ Designated as safety issue: Yes ]
  • Adverse clinical events and measures of renal function [ Time Frame: 6 weeks post-angiogram ] [ Designated as safety issue: Yes ]
  • Health related quality of life [ Time Frame: 6 weeks post-angiogram ] [ Designated as safety issue: No ]
  • Subgroup analyses based on (a) diabetes; (b) amount of contrast; and (c) baseline creatinine [ Time Frame: Within 48 hours of angiogram ] [ Designated as safety issue: No ]

Estimated Enrollment: 200
Study Start Date: May 1996

Arms Assigned Interventions
Experimental: Intervention
Saline hydration + mannitol + furosemide
Drug: intravenous saline hydration + mannitol + furosemide
500 mls half-normal saline + 25g mannitol + 100 mg furosemide
Placebo Comparator: Controls
Saline hydration without mannitol or furosemide
Drug: intravenous saline hydration
500 mls half-normal saline

Detailed Description:

Patients with pre-existing kidney disease are at high risk of acute renal failure when exposed to radio-contrast dyes, for example during a cardiac angiogram.

We hypothesize that an infusion of saline + furosemide + mannitol will reduce rates of contrast-induced nephropathy when compared with saline infusion controls.

We define an episode of contrast nephropathy using the conventional often published definition of a 25% relative increase in serum creatinine OR a 44 umol absolute increase in serum creatinine within 48 hours of contrast exposure.
