We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
1. Patients with chronic stable renal impairment as evidenced by a creatinine >133µmol//L or creatinine clearance < 50ml/min as estimated by the Cockcroft- Gault formula20. ( Creatinine clearance or CrCl will be calculated by applying the Cockcroft- Gault formula to the baseline serum creatinine level: (140 – age) x weight/ serum creatinine x 0.815; with a female adjustment: CrCl female = CrCl x 0.85)2. Patients undergoing cardiac surgery requiring cardiopulmonary bypass including but not exclusive to coronary artery bypass grafting (CABG), valve surgery, combination CABG and valve replacement procedures, adult patients undergoing surgery for congenital heart disease, repairs of ventricular aneurysm, septal defect repairs and removal of myxomas, stable patients with intraaortic balloon pump (IABP) inserted electively preoperatively, redo cases requiring cardiopulmonary bypass (CPB). 3. Patients who have given consent.
