About this study

Official title: N-Acetylcysteine Protects Against Acute Renal Insult in Patients With Abnormal Renal Function Undergoing Cardiopulmonary Bypass.

The purpose of this study is to determine whether N-acetylcysteine is effective in the prophylaxis of post-cardiopulmonary bypass acute renal impairment.

Read the detailed description

BACKGROUND Reactive oxygen species have been shown to cause contrast-induced nephrotoxicity (CIN). According to previous studies, the N-acetylcysteine has been proved to be advantageous in the avoidance of CIN. We seek to evaluate the efficacy of the antioxidant N-acetylcysteine in limiting the nephrotoxicity after cardiovascular surgery with cardiopulmonary bypass.

METHODS We will prospectively study 60 patients who will receive a cardiovascular surgery with cardiopulmonary bypass. Patients will be randomly assigned to receive either N-acetylcysteine (600 mg orally twice daily for 4 doses) with 0.45% saline intravenously, before and after cardiopulmonary bypass, or placebo with 0.45% saline. Serum creatinine and blood urea nitrogen will be measured before, 48 h and 5 days after the operation procedure.

Expected results Prophylactic oral administration of the antioxidant N-acetylcysteine, along with hydration, will significantly reduce the acute renal damage induced by CPB in patients with chronic renal insufficiency that need cardiovascular procedures.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing N-Acetylcysteine 600mg/tab in people with Cardiovascular Disease and Renal Insufficiency, Acute, run by Far Eastern Memorial Hospital at 1 site in Taiwan.

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 5 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: paused, as of the sponsor's last update on 9 Feb 2009. 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 Taiwan. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

Serum creatinine and blood urea nitrogen: before, 48 h and 5 days after the operation procedure.. 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 9 Feb 2009.
