Effects of Dexmedetomidine & Dopamine on Renal Function After Major

Status Recruiting

Clinical Trial Summary

Acute kidney injury (AKI) is associated with complications that may lead to multiorgan dysfunction and potentially to multi-organ failure after major surgery. Dexmedetomidine is a highly selective alpha(2)-adreno receptor agonist widely used during anesthesia. In animals, dexmedetomidine has shown protective effects in AKI after surgery. Dopamine (DA) is an organic chemical of the catecholamine and phenethylamine families that has been widely used to increased renal blood flow and urine output during surgery. However, the clinical effects of dexmedetomidine and dopamine on renal function are still controversial. The aim of this study is to investigate whether dexmedetomidine and dopamine have positive effects on renal function after selective major surgery.

Clinical Trial Description

Acute kidney injury (AKI) is associated with complications that may lead to multiorgan dysfunction and potentially to multi-organ failure in critically ill patients. AKI accounts for 5-10% after general surgery to 45% after cardiac surgery during hospital stays and tends to be associated with increased length of hospital stay as well as increased morbidity and mortality. Even slight increases in postoperative serum creatinine concentrations have been associated with almost 5-fold increases in mortality. Dexmedetomidine is a potent and highly selective alpha(2)-adreno receptor agonist that has analgesic, sedative, anxiolytic, and sympatholytic effects. In animals, dexmedetomidine has shown protective effects in several models of ischemia-reperfusion, which is thought to be the principal mechanism of AKI in the context of surgery. Dopamine (DA) is an organic chemical of the catecholamine and phenethylamine families that has been widely used to increased renal blood flow and urine output. However, the clinical effects of dexmedetomidine and dopamine on renal function are still controversial. The aim of this study is to investigate whether dexmedetomidine and dopamine have positive effects on renal function after selective major surgery. ;

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.
