Perioperative Versus Postoperative Glycemia Control in Cardiac Surgery Patients
Perioperative and Postoperative HyperglycemiaTight Glycemia ControlIt 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.
Diabetes in the Elderly: Prospective Study
DiabetesHyperglycemiaDiabetes is highly prevalent in the elderly, afflicting about 20% of older adults aged 65-75 years and 40% of adults >80years of age. It is expected that the number of elderly people suffering from diabetes will increase in the future, as general life expectancy is increasing. Nursing home residents with diabetes have higher rates of serious comorbidities and have greater activity of daily living dependencies than other residents without diabetes. In addition, persons with diabetes have higher risk of hypertension, heart disease, stroke depression, cognitive impairment, and cardiovascular mortality than individuals without diabetes. There are a few retrospective studies in elderly patients analyzing quality of diabetes care and glycemic control adjusted for medications and presence of co-morbidities in long-term care facilities; however, no previous randomized controlled trials have demonstrated benefits of glycemic control on clinical outcome, quality of life, and rate of acute metabolic complications (hyperglycemia and hypoglycemic events) in long-term care facilities. In addition, it is not known whether the use of basal insulin is superior to treatment with sliding scale insulin (SSI) in long-term care facility residents with type 2 diabetes. Accordingly, the investigators propose to conduct a prospective randomized control trial comparing the efficacy and safety of the basal (glargine) insulin regimen and sliding scale regular insulin in the management of nursing home patients with T2DM.

Stop Emergency Room Visits for Hyperglycemia Project - District of Columbia (DC)
Type 2 Diabetes MellitusTo demonstrate that a focused Emergency Department (ED) intervention for uncontrolled hyperglycemia enables safe and effective glycemic management and reduces emergency room re-visits. We assessed hypoglycemia BG < 60mg/dL; change in mean blood glucose and A1C, and ED revisits for hyperglycemia.
Clinical Risk Assesment of CS-1 Decision Support System
HyperglycemiaCritically Ill PatientsThis is a single-center, open, non-controlled clinical investigation in 10 patients at the Medical University Graz including a treatment visit (V1)and a follow up visit(V2). In the treatment visit (V1) after admittance to the ICU arterial blood glucose values will be monitored and either the software-algorithm eMPC will be used to adjust the infusion rate of intravenously administered human soluble insulin to normalise arterial blood glucose. The purpose of the present study is to investigate the performance of the already developed and tested algorithm in combination with a newly developed bed-side, touch screen user interface (CS-1 decision support system) in patients at the medical ICU for a period of 72 hours. Follow up information(V2) will be acquired at hospital discharge or at the latest one week after visit 1.
Comparative Trial Between 3 Types of Insulin Infusion Protocols
HyperglycemiaIncreasing evidence from observational studies in hospitalized patients with and without diabetes indicates that hyperglycemia is a predictor of poor outcome. Over the short-term, hyperglycemia can adversely affects fluid balance (through glycosuria and dehydration), impairs immunologic response to infection, and promotes inflammation and endothelial dysfunction. Blood glucose control with intensive insulin therapy in patients with acute critical illness reduces the risk of multiorgan failure and systemic infections, and decreases short- and long-term mortality . - Hypotheses: we hypothesize that management of inpatient hyperglycemia with a computer-guided intravenous infusion protocol (Glucommander) will facilitate a smoother glycemic control with a lower rate of hypoglycemic events than treatment following a standard insulin infusion algorithm or a simple calculated infusion protocol in critically ill patients in the medical and surgical ICU.
Tight Glycemic Control by eMPC Algorithm in Medical ICU Patients.
Critically Ill PatientsMechanical Ventilation1 moreThis is an open mono-centre randomised controlled trial performed at the Medical University Graz including a treatment visit (V1). In the treatment visit (V1) after admittance to the ICU arterial blood glucose values will be monitored and either the software-algorithm eMPC will be used to adjust the infusion rate of intravenously administered human soluble insulin to normalise arterial blood glucose or routine treatment will be used to establish tight glycaemic control. The treatment visit will last for 72 hours. The primary hypothesis of the study is that blood glucose control by the eMPC algorithm is not inferior compared to the implemented routine protocol.
Outcomes With Tight Control of Hyperglycemia in Cardiac Surgery Patients
Cardiac Surgical ProceduresHyperglycemiaPatients with or without diabetes may have high blood sugar levels due to stress response of the body during heart surgery. This study is being done to determine if maintaining normal blood sugar levels during open-heart surgery by using intravenous insulin results in a lesser incidence of death, wound infections in the chest, disturbances of heart rhythm, kidney failure, stroke and prolonged time on the breathing machine (artificial ventilation) within 30 days after surgery.
Intensive Insulin Therapy in Non-diabetic Patients With Acute Myocardial Infarction and Hyperglycaemia...
DiabetesHyperglycemia1 moreHyperglycemia at admission has been associated with bad prognosis in patients with acute myocardial infarction (AMI). The clinical benefit of intensive treatment with insulin has been evaluated in diabetic patients admitted to intensive care units. The aim of our study was to assess the short-term effects and the safety of strict glycemic control in subjects with AMI and hyperglycemia without a previous history of diabetes.
Pilot Study to Evaluate a Method of Controlling High Blood Sugar in the Pediatric Intensive Care...
HyperglycemiaRecent studies of adult intensive care unit (ICU) patients have shown significantly decreased morbidity and mortality when blood sugar concentrations are closely controlled. The safety and efficacy of this type of blood sugar management has not been studied in the pediatric ICU population. Based on the current pediatric literature data as well as our extensive retrospective study, blood sugar concentrations have a potentially profound role to play among PICU patients. In preparation for a multi-center randomized control trial, we propose a prospective feasibility study to evaluate the safety and effectiveness of using an insulin delivery algorithm to manage blood sugar in the PICU. Our hypothesis for this feasibility trial is that uniformly monitoring and controlling blood glucose with a Discrete-Closed-Loop(DCL) insulin delivery algorithm will be an effective, safe, and consistent means of delivering insulin to manage glucose in the pediatric intensive care unit.
