About this study
Official title: Ability of N-acetylcysteine to Prevent Deterioration in Renal Functioning in CKD Patients Undergoing Major Surgery Under General Anesthesia
Acute kidney injury (AKI) is one of the most serious and frequent complication of general anesthesia. Patients suffer from chronic kidney diseases (CKD) predispose to develop AKI. CKD patients often need some surgical interventions that have been done under general anesthesia; they therefore have an increased probability to develop AKI.
N-acetylcysteine (NAC), a thiol compound with antioxidant and vasodilatory properties, reduces oxygen free radical production, decreases pump-related ischemia-reperfusion injury and the levels of pro-inflammatory cytokines. NAC has been reported to protect the kidney from injury induced by contrast media, ischemia, and toxins.

Present study aimed to explore the efficacy of NAC treatment to prevent deterioration in renal functioning in CKD patients undergoing major surgery under general anesthesia.
Study will include about 200 CKD (eGFR (estimated glomerular filtration rate) less than 40) patients that should undergo surgical interventions under general anesthesia and will divide to 3 groups as follows: group 1- about 40 patients which should undergo major vascular surgery; group 2 - about 60 patients that suppose to undergo major orthopedic surgery (revision of total hip, revision of knee); group 3 - about 100 patients undergoing major abdominal surgery. Patients from each group will randomly divide in two sub-groups (A and B). Subgroup A will receive NAC twice (14-16h and 2h) before surgery and 12h after surgery. Subgroup B will receive placebo (saline).
Markers for kidney function such as eGFR, creatinin, urea, electrolytes, cystatin C, NGAL (Neutrophil Gelatinase-Associated Lipocalin), urine albumin will measure before and after surgery in all patients. An additional blood samples for assessment of nitric oxide and cytokine levels will be taken from each patient before and after surgery.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Acute kidney injury (AKI) is one of the most serious and frequent complication of general anesthesia. Patients suffer from chronic kidney diseases (CKD) predispose to develop AKI. CKD patients often need some surgical interventions that have been done under general anesthesia; they therefore have an increased probability to develop AKI.
N-acetylcysteine (NAC), a thiol compound with antioxidant and vasodilatory properties, reduces oxygen free radical production, decreases pump-related ischemia-reperfusion injury and the levels of pro-inflammatory cytokines.

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: status not confirmed, as of the sponsor's last update on 1 Dec 2010. 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 Israel. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Contact Zoya Haitov, MD (972-8-9779466, ZoyaC@asaf.health.gov.il), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
parameters of kidney function. 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 1 Dec 2010; AzTrials last refreshed its copy on 8 Nov 2026.
