Filter by:This study investigates the effect of two dose-levels of AP214 on the prevention of (acute) kidney injury after cardiac surgery.
The aim of this study is to assess the effect of minimal (MECC) versus conventional (CECC) extracorporeal circulation on neurocognitive function after elective coronary bypass grafting (CABG) as well as whether this can be attributed to improved cerebral perfusion intraoperatively.
INTRODUCTION. Cell-derived microparticles (MP) are released in cell activation, apoptosis and other processes. MP derived from red cells (RMP) are known to be released from stored packed red blood cells (PRBC), and their number increases with storage time. This constitutes one aspect of the storage lesion. Adverse transfusion events are known to increase with time of PRBC storage. The explanation for this is not known. HYPOTHESIS. Based on their findings and those of others, the investigators propose to test the hypothesis that MP in stored PRBC contribute to adverse effects of transfusion. Specifically, MP in stored blood: (1) increase procoagulant activity, expression of pro-inflammatory mediators, immune suppression, and endothelial disturbance; and (2) increase the risk of transfusion and post-operative complications in patients undergoing coronary artery bypass grafting (CABG). AIMS & PROCEDURES. The aim of this study is to assess the clinical significance of MPs in PRBC-related transfusion complications utilizing washed PRBC. Packed red blood cells (PRBC) will be washed at the blood bank to obtain MP depleted PRBC (PRBC-MP). A total of 500 patients undergoing CABG will be initially randomized to 2 groups: one to receive PRBC-MP, and the other conventional PRBC (PRBC+MP). Using a panel of lab tests/biomarkers selected for high sensitivity the investigators will compare the 2 groups with respect to subclinical physiologic host responses including (i) endothelial disturbances, (ii) inflammatory, and (iii) procoagulant responses. In addition, clinically evident transfusion complications and short term (<=30 days) surgical complications will be assessed and compared. Patients who are randomized but end up not requiring transfusion at surgery will serve as controls. Laboratory and clinical results will also be evaluated to elucidate which tests are significantly associated with clinically adverse effects. SIGNIFICANCE. This study will shed new light on the biochemical and clinical effects of transfusion of MP. The findings of this investigation could significantly improve transfusion practice and safety.
This research study is designed to better understand post-operative complications as related to the tightness of blood sugar control. It is also hoped that we may learn that a more liberal control of your blood sugars is not inferior to the current strict glucose control. Our ultimate goal is to evaluate if there is any change in the rates of complications between the two groups. We will be comparing the current strict blood glucose control with a more liberal target for blood sugars.
The specific aim of the SOS-Xience V study is to examine the 12-month incidence of binary angiographic in-stent restenosis after implantation of the Xience V stent in aortocoronary saphenous vein bypass graft lesions.
The purpose of this trial is to study the effects of preoperative antithrombin supplementation in patients undergoing cardiac surgery with cardiopulmonary bypass in order to maintain antithrombin levels in a range greater than 58% and, eventually, to decrease negative clinical outcomes during the ICU stay.
Objective: To evaluate the safety and cost-effectiveness of Short Stay Intensive Care (SSIC) treatment for low-risk coronary artery bypass patients Design: Randomized clinical equivalence trial Setting: University Hospital Maastricht, the Netherlands Patients: low-risk coronary artery bypass patients Interventions: 600 patients were randomly assigned to undergo either SSIC treatment (8 hours Intensive Care) or control treatment (care as usual, overnight Intensive Care). Measurements: The primary outcome measures were Intensive Care (IC) readmissions and total hospital stay. The secondary outcome measures were total hospital costs, Quality of Life (QoL), postoperative morbidity and mortality. Hospital costs consisted of the cost of hospital admission(s) and outpatient costs.
Pleural effusion is a common complication of cardiac surgery. The aim of this study was to determine the prevalence, characteristics and determinants of clinically significant pleural effusions, defined as those requiring therapeutic pleural drainage.
The purpose of this study is to determine whether pretreatment with atorvastatin protects against atrial fibrillation following off-pump coronary artery bypass graft surgery.
The investigators' hypothesis is that restriction of circulating fluids in comparison to a liberal fluid administration policy would lead to a reduction of allogenic red blood cells exposure in patients undergoing cardiopulmonary bypass (CPB) for primary coronary artery bypass graft supported by reinfusion of washed shed blood from thoracic cavities.
