Tight Glycemia Control clinical trials

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.

Perioperative Versus Postoperative Glycemia Control in Cardiac Surgery Patients

Start date: January 2007
Phase: N/A
Study type: Interventional

It is known that acute stress of organism often leads to hyperglycemia even in nondiabetic patients. It is also known that pathophysiological mechanisms: enhanced gluconeogenesis, impaired insulin secretion and decreased insulin sensitivity due to anti-insulin effect of stress hormones and proinflammatory cytokines, or changes of glucose excretion and renal tubular resorption. Many studies proved the negative effects of hyperglycemia to different tissues and organs, e.g. hearth (increasing size of myocardial necrosis, reducing coronary collateral blood flow, exaggerating ischemia-reperfusion injury, impairing ischemic preconditioning), vascular (increased risk of thrombosis, endothelial dysfunction, activation of systemic inflammation with destabilization of atherosclerotic plaques), kidneys and its association with infectious complications. The first Leuven study (published in 2001) demonstrated that hyperglycemia in critical care patients significantly increases risk of organ complication and total mortality. Although the importance of postoperative tight glycemia control is now widely accepted, glycemia stability during cardiac surgery is often neglected. It is known that postoperative hyperglycemia has negative effects, but it is not known what effect has its peroperative elevation. Goal of this study is to demonstrate, whether full perioperative intensive glycemia control can reduce the incidence of postoperative morbidity even more than postoperative glycemia control only.
