Filter by:This is a two-arm randomized parallel study. Patients who will be meeting the above-mentioned criteria and agree to take part in the study, were asked to sign an informed consent prior conducting the study. The whole study protocol were presented to the local institutional review board (IRB).
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.
Perla® is a Cold Preservation Solution, with purpose to wash out, preserve during transport liver and kidney grafts in optimal conditions from the donor to the recipient. The purpose of the PERTRIAL clinical investigation is to demonstrate the Performance and Safety of Perla® Cold Preservation solution.
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.
Myocardial protection has become an essential adjunctive measure in cardiac surgery to bail the myocardium out of ischemia/reperfusion-induced damage during the operation. Experimental studies have shown that lipid emulsion infusion just before reperfusion (i.e., intralipid postconditioning (ILPC)) could reduce myocardial infarct sizes, improve cardiac function, and reduce myocardial I/R injuries, despite the interesting experimental findings, the potential clinical usage of lipid emulsion in preventing myocardial I/R injury needs to be further investigated.
Severe ischemic changes of the liver remnant after hepatectomy could expedite tumor recurrence on the residual liver. Our study aimed at assessing the effect of warm ischemic/reperfusion (I/R) injuries on surgery-to-local recurrence interval and patient overall survival, during major hepatectomies under inflow and outflow vascular control.
Study will investigate & compare the left ventricular remodeling & systolic function between two groups of ST-elevation myocardial infarction undergoing primary per-cutaneous coronary intervention applying ischemic post-conditioning to one of them.
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).
Remote ischemic preconditioning (RIPC) has shown organ-protective effects in many clinical settings including patients with ischemic heart disease. However its protective role in head and neck cancer patients with preoperative radiotherapy undergoing free flap reconstructive surgery has not yet been evaluated. The purpose of the current study is to evaluate the effect of RIPC on tissue oxygen saturation and skin temperature of the flap.
