Filter by:As a simple auxiliary tool for lower extremity orthopedic surgery, tourniquet can effectively reduce intraoperative bleeding and ensure the clarity of the operative field, effectively shorten the operation time and improve the operation efficiency. The extensive use of tourniquets in lower extremity surgery will not only cause local paralysis, pain and other complications, but also bring about postoperative complications such as large drainage volume and deep vein thrombosis. Recent studies have found that tourniquet induced ischemia-reperfusion injury not only affects the local tissue structure and function of skeletal muscle, but also causes reperfusion injury in distant organs (such as heart, lung and brain). Therefore, improving tourniquet ischemia-reperfusion injury after knee replacement is of great significance to improve the quality of life of patients during the perioperative period. Therefore, the aim of this study was to investigate the effects of dexmedetomidine and tourniquet pretreatment on myocardial injury and brain injury caused by lower extremity ischemia-reperfusion.
To evaluate whether retrograde venous reperfusion of a renal graft before antegrade arterial reperfusion can reduce ischemic-reperfusion injury. All registered eligible candidates for kidney transplant will be randomized to receive either: - retrograde venous, then arterial reperfusion or - antegrade arterial reperfusion.
The investigators hypothesize that preconditioning neurologically deceased organ donors with the calcineurin inhibitor tacrolimus will improve short and long-term transplant survival without causing harm. Organ donors will be randomized to receive either 0.02 mg/kg ideal body weight (IBW) of tacrolimus single infusion or placebo before organ recovery. All corresponding recipients are enrolled and data is collected up to 7 days post-transplant to determine graft function and at 1 year to collect outcomes of vital status, re-transplantation and dialysis. The CINERGY Pilot Trial assesses feasibility for the main trial.
Hypoxic-ischaemic brain injury (HIBI) is the main cause of death in patients who are comatose after resuscitation from cardiac arrest. Current guidelines recommend to target a mean arterial pressure (MAP) above 65 mmHg to achieve an adequate organ perfusion. Moreover, after cardiac arrest, cerebral autoregulation is dysregulated and cerebral blood flow (CBF) depends on the MAP. A higher blood pressure target could improve cerebral perfusion and HIBI. Transcranial Doppler (TCD) is a non-invasive method to study CBF and its variations induced by MAP. The aim of this study is to test the feasibility of an early-goal directed hemodynamic management with TCD during the first 12 hours after return of spontaneous circulation (ROSC).
The purpose of this study is to evaluate the impact of normothermic machine perfusion in liver transplantation using grafts of brain death donors older or equal than 70 years
This trial is a 2 x 2 factorial design, double-blinded, randomized controlled trial to evaluate efficacy and safety of remote ischemic preconditioning and postconditioning for prevention of contrast-induced acute kidney injury in patient undergoing coronary angiography and angioplasty
This trial is a 2 x 2 factorial design, double-blinded, randomized controlled trial to evaluate efficacy and safety of remote ischemic preconditioning and postconditioning in patient undergoing coronary angioplasty.
The investigators want to measure the degradation of the endothelial glycocalyx before and after clamping the aorta, in patients operated for a abdominal aortic aneurism.
The purpose of this study is to determine whether Remote Ischemic Perconditioning is effective on Acute kidney injury in adult valve replacement.
