Filter by:Age is no longer an absolute contraindication to cardiac surgery therefore there is often need for combined interventions (double valve repair/replacement, or coronary artery bypass graft and valve repair/replacement) with relative prolongation of cardiopulmonary bypass time. Prolonged cardiopulmonary bypass use causes an increase in the inflammatory response, and on the other a need for blood reinfusion and therefore lipid microemboli from the operative field. The clinical consequences for patients are post-operative delirium and post-operative cognitive impairment. These two neurological complications involve up to 45% of elderly patients undergoing cardiac surgery and have a significant impact on quality of life, hospitalization and mortality in the short and long term. The Remowell 2 oxygenator system has demonstrated in preliminary studies that, compared to the gold standard Inspire oxygenator, it can guarantee a significant reduction of hemodilution, inflammatory systemic response and embolization of lipid microemboli and leukocytes. In light of these considerations, it is possible to formulate the hypothesis that the use of the Remowell 2 device can contribute to significantly reducing the onset of post-operative delirium and cognitive impairment. The present study is designed to validate this hypothesis in a randomized controlled scenario.
Tissue hypoperfusion during cardiopulmonary bypass (CPB) affects cardiac surgical outcomes. Lactate, an end product of anaerobic glycolysis from oxygen deficit, is an obtainable marker of tissue hypoxia. The investigators aimed to determine the value of blood lactate level during CPB in adult cardiac surgeries in predicting outcomes. The investigators retrospectively reviewed the patients underwent cardiac surgeries with CPB from January 2015 to December 2015. The patient's characteristics, pre-operative status, surgical type, and intra-operative lactate levels were collected. The outcomes were in-hospital mortality and complications. Receiver operating characteristics (ROC) curves were used to assess the ability of peak lactate level during CPB to predict in-hospital mortality.
This prospective randomized study elucidates the effects of exogenous nitric oxide delivered to the extracorporeal circulation circuit for cardioprotection against ischemia-reperfusion injury during coronary artery bypass graft surgery with cardiopulmonary bypass.
The main objective of this study is to measure the incidence of postoperative infections in 2 groups of patients: one group of patients ventilated and one group of patients without mechanical ventilation during cardiopulmonary bypass for cardiac surgery, and demonstrate that the incidence of postoperative infections is significantly lower in patients ventilated during cardiopulmonary bypass.
The purpose of this randomized controlled trial is to evaluate a fully automated algorithm for the establishment of glycemic control in diabetic patients and to compare the results with routine management of hyperglycemia in patients undergoing cardiopulmonary bypass surgery.
Diagnosis of pneumonia remains difficult in intensive care unit (ICU), notably after cardiac surgery. Lung ultrasonography (LUS) has been successfully used for diagnosis of pneumonia, but its usefulness and reliability was never evaluated after cardiac surgery. This study investigates the clinical relevance of LUS for pneumonia diagnoses in cardiac ICU.
Glyceryl trinitrate is used in coronary artery bypass grafting surgery. This surgery frequently employs hypothermic cardiopulmonary bypass, where the whole body is cooled down to 28-32 °C to arrest the heart, and protect the organs from ischemic insult. When the cardiac repair or grafting is done, the body is warmed to 37 °C. During this "rewarming period", the heart has to beat against the vessels, all of which are constricted due to hypothermia. To overcome this constriction of the vessels, and decrease the workload of the heart, glyceryl trinitrate is infused. This drug causes significant dilatation in arteries and veins, which allows the heart to pump the blood with less force. The dilatation of the vessels also allows the body to rewarm more easily. The investigators' concern is whether increased infusion rates of glyceryl trinitrate may cause uncontrolled rewarming of the brain or not. The investigators will measure the temperature of the brain using a temperature probe located in the nasal cavity. The temperature will be recorded at each minute during the the rewarming period. Results of two commonly used infusion rates of glyceryl trinitrate will be compared.
This trial investigates whether a multimodal cardioprotection per-surgery therapeutic strategy could reduce myocardial injury in patients undergoing cardiac surgery compared to traditional management. The primary endpoint is the AUC (area under the curve) of the hypersensitive troponin I. Blood samples will be collected during the 72 hours following the aortic cross-unclamping. This trial is a French, multicenter, randomized, single-blinded and controlled trial. 210 patients will be enrolled with a clinical follow-up during 30 days.
In this observational study a comparison is made between two different monitors for measurement of the activated clotting time (ACT): mechanical versus biochemical techniques
Retrospective study determine whether ulinastatin enhances postoperative pulmonary oxygenation after cardiopulmonary bypass (CPB).
