Filter by:There is actually two techniques of subclavian vein ultrasonography-guided venous catheterization : the axial and longitudinal approach. Currently, nothing makes it possible to privilege one technique compared to the other. This study aims to determine the best ultrasonography-guided method.
In cardiac operations under cardiopulmonary bypass(CPB), monitoring of brain tissue oxygen saturation with infrared spectrophotoscopy leads to a reduction of the number of packed red cell(PRC) transfusions during the period of extracorporeal circulation.
The purpose of this study is to evaluate the effects of Remote Ischemic Preconditioning on cognitive function in patients undergoing cardiac surgery compared to control intervention.
This study will compare the clinical efficacy and safety of Voluven® and Human Albumin during elective open-heart surgery in pediatric patients.
Several studies have highlighted the cardioprotective effects of acute normovolemic hemodilution during cardiac surgery. The aim of our study is to show that an increase in endogenous erythropoietin (EPO) might explain the cardioprotective effects of acute normovolemic hemodilution against ischemia-reperfusion phenomena.
Patients undergoing high risk cardiac surgery (combined CABG and valvular procedures) will be randomized to receive a total intravenous anesthesia or an anesthesia plan with sevoflurane. The investigators want to document whether the cardioprotective properties of volatile agents could translate in an improved outcome after cardiac surgery in high risk patients.
The purpose of this study is to investigate changes in new plasma stroke biomarker panel in patients undergoing cardiac surgery with the use of cardiopulmonary bypass.
The aim of the study is to test the efficiency of intravenous administration of metoprolol versus intravenous administration of amiodarone in the prevention of atrial fibrillation after cardiac surgery.
Cardiac surgery is bleeding requiring transfusion surgery . The haemorrhagic is related to the need to use high doses of anticoagulants to prevent thrombosis of blood . Moreover, this type of surgery is platelets and coagulation factors consumming despite conducting a thorough anticoagulation. All these changes contribute to increase the need for transfusions during heart surgery. The main objective of this study is to compare the need for transfusions in patients suffering from bleeding complications after cardiac surgery with a therapeutic algorithm based on the use of ROTEM ® versus standard tests based solely on standard laboratory tests. 100 pateinst (50 in each arm) should be included in this trial.
With over one million operations a year, cardiac surgery with cardiopulmonary bypass is one of the most common major surgical procedures worldwide (1). Acute kidney injury is a common and serious postoperative complication of cardiopulmonary bypass and may affect 25% to 50% of patients (2-4). Acute kidney injury carries significant costs (4) and is independently associated with increased morbidity and mortality (2,3). Even minimal increments in plasma creatinine are associated with an increase in mortality (5,6). Multiple causes of cardiopulmonary bypass-associated acute kidney injury have been proposed, including ischemia-reperfusion, generation of reactive oxygen species, hemolysis and activation of inflammatory pathways (7-10). COMT LL genotype appears to increase the risk of vasodilatory shock and AKI after cardiac surgery. To date, no simple, safe and effective intervention to prevent cardiopulmonary bypass-associated acute kidney injury in a broad patient population has been found (11-14). Urinary acidity may enhance the generation and toxicity of reactive oxygen species induced by cardiopulmonary bypass (10,15). Activation of complement during cardiac surgery (16) may also participate in kidney injury. Urinary alkalinization may protect from kidney injury induced by oxidant substances, iron-mediated free radical pathways, complement activation and tubular hemoglobin cast formation (9,17,18). Of note, increasing urinary pH - in combination with N-acetylcysteine (19,20) or without (21) - has recently been reported to attenuate acute kidney injury in patients undergoing contrast-media infusion. In a pilot double-blind, randomized controlled trial the investigators found sodium bicarbonate to be efficacious, safe, inexpensive and easy to administer. These findings now need to be confirmed or refuted by further clinical investigations in other geographic and institutional settings. Accordingly, the investigators hypothesized that urinary alkalinization might protect kidney function in patients at increased risk of acute kidney injury undergoing cardiopulmonary bypass needs to be confirmed in an international multicenter, double-blind, randomized controlled trial of intravenous sodium bicarbonate.
