Targeted Blood-pressure Management & Acute Kidney Injury After Coronary

Status Recruiting

Clinical Trial Summary

Acute renal injury (AKI) is a common complication after cardiac surgery and is associated with worse outcomes. It is now realized that intraoperative hypotension is an important risk factor for the development of AKI. In a recent randomized controlled trial of patients undergoing major noncardiac surgery, intraoperative individualized blood-pressure management reduced the incidence of postoperative organ dysfunction. The investigators hypothesize that, for patients undergoing off-pump CABG, targeted blood-pressure management during surgery may also reduce the incidence of postoperative AKI.

Clinical Trial Description

Acute renal injury (AKI) is a common complication after cardiac surgery. In patients undergoing noncardiac surgery, intraoperative hypotension may lead to hypoperfusion of important organs and result in organ injuries such as AKI, myocardial injury, and stroke. The development of organ injuries is associated with wose outcomes including higher 30-day or even 1-year mortality. In a recent randomized controlled trial, patients undergoing major noncardiac surgery received either individualized (systolic blood pressure [SBP] maintained within 10% of the reference level) or standard (SBP maintained above 80 mmHg or within 40% of the reference level) blood-pressure management strategy during surgery. The results showed that individualized blood-pressure management reduced the incidence of postoperative organ dysfunction. Intraoperative hypotension is very common during off-pump coronary artery bypass grafting (CABG) surgery. The investigators hypothesize that, for patients undergoing off-pump CABG, good blood-pressure management with norepinephrine may also reduce the incidence of postoperative AKI. The purpose of this study is to investigate the effect of targeted blood-pressure management during off-pump CABG surgery on the incidence of postoperative AKI. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
