About this study
Official title: Comparing Sodium Bicarbonate Plus Isotonic Normal Saline Versus Isotonic Normal Saline Alone to Prevent Contrast-Induced Nephropathy in Patients Undergoing Coronary Angiography: A Randomized Controlled Trial
Radio Contrast Induced Nephropathy (RCIN) remains a well recognized complication in patients undergoing diagnostic or interventional procedures requiring radiographic contrast agents. Recent studies have shown benefit in administering Sodium Bicarbonate over normal saline( the uniformly accepted prophylaxy) in preventing RCIN.Therefore the aim of the study is to evaluate the efficacy of sodium bicarbonate solved in normal saline compared with infusion of normal saline in prevention of RCIN.
Read the detailed description
Radio Contrast Induced Nephropathy (RCIN) remains a well recognized complication in patients undergoing diagnostic or interventional procedures requiring radiographic contrast agents and is the third leading cause of acquired acute renal failure in hospitalized patients. Strategies for the prevention of radiocontrast nephropathy have focused on countering vasoconstriction (pre-hydration, fenoldopam, and theophylline), enhancing flow through the nephron (diuretics), or protection against oxygen-free-radical injury (urinary alkalinization and N-acetylcysteine).
Among all prophylactic measures that have been proposed, adequate preprocedural and postprocedural hydration has demonstrated effectiveness in the prevention of radiocontrast nephropathy. Thus, it remains the most frequently applied measure in clinical practice.
A Recent study in May 2004 have shown benefit in administering Sodium Bicarbonate over normal saline as a prophylaxy.Since alkalizing renal tubular fluid with bicarbonate may reduce injury.
Comparisons: IV 154 mEq/L solution of NaCl 0.9% OR IV 154 mEq/ L sodium bicarbonate solved in 154 mEq/ L NaCl 0.9%. Each fluid is infused at the rate of 3 ml/kg/ hour one hour before the angiographic procedure, continuing at the rate of 1 ml/kg/ hour for 6 hours after the procedure. Maximum rate of fluid permitted is that for a body weight of 110 Kg.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Sodium Bicarbonate plus normal saline 0.9% and normal saline 0.9% in people with Contrast Induced Nephropathy, run by Tehran University of Medical Sciences at 1 site in Iran.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 5 Sep 2008. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Iran. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
development of contrast induced nephropathy defined as an absolute (> or = 0.5 mg/dl) or relative increase (> or = 25%) in serum creatinine at 48 hours after exposure to a contrast agent compared to baseline serum creatinine values. (time frame: at 48 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Sep 2008.
