Filter by:Arterial hypotension during general anesthesia remains a factor of poor outcomes, increases the risk of myocardial infarction, acute kidney injury and 1-year mortality. Furthermore, arterial hypotension may also decrease cerebral perfusion contributing to worsen neurological outcome. It seems necessary to monitor cerebral perfusion during anesthesia and to define individual dynamic targets of blood pressure. The goal of this study is to evaluate cerebral perfusion change in adult patients with or without cardiovascular risk factors during a standardized propofol-remifentanil anesthesia induction. Cerebral perfusion will be evaluated and compared using the simultaneously measure of TCD, NIRS and BIS. Those measures will be also repeated during and after treatment of arterial hypotension episodes in both groups.
During general anaesthesia, intraoperative hypotension (IOH), defined as a mean arterial pressure (MAP) drop of more than 20%, is frequent with potential deleterious effects for patients. Pulse oximeter is mandatory in the operating room making photoplethysmographic (PPG) signal and parameters such as the relative dicrotic notch height (Dicpleth) or the perfusion index (PI) readily available. The purpose of this study is to investigate whether Dicpleth and PI could detect IOH during anaesthesia induction and follow their variations during vasopressor boluses.
Transplant rejection is one of the biggest limitations in renal transplant procedures, where the kidney can undergo an acute, late acute, or chronic transplant rejection. With the advancement in transplantation protocols, acute survival of renal transplants has improved, but long-term survival is still unsatisfactory, as most of the renal transplants develop chronic graft rejection. Unfortunately, there is little the investigators know when it comes to improving long-term survival of renal transplants. Mesenchymal stem cells (MSC) have been shown to have immunosuppressive and repairing properties. The purpose of this study is to find out whether MSC in combination with standard therapy of antibody mediated rejection (ABMR) are more effective in preventing organ deterioration and maintaining kidney function.
Rigorous clinical practice assessment is a key factor to improve patient's care and prognosis in interventional cardiology (IC). A multicentric IC observational study (CRAC), fully integrated to usual coronary activity report software, started in Centre Val de Loire (CVL) region in 2014. CRAC observatory was conduced on five IC CathLab of CVL region. Quality of collected data is regularly evaluated and allowed building an exhaustive, and reliable database. This solution could easily be developed in other French regions.
To evaluate the effect and safety of noninvasive ventilation assisted interventional bronchoscopy for hypoxemia patients with central airway stenosis. With the sedation and analgesia, noninvasive ventilation assisted interventional bronchoscopy for hypoxemia patients with central airway stenosis is safe and effective, carries high satisfaction rate.
