Filter by:The study aimed to evaluate the combined effects of cyclosporine and remote ischemic preconditioning on MDA, calcium cytosol concentration, and mitochondrial edema in tetralogy Fallot patients undergoing corrective surgery.
Prophylactic effect of nirmatrelvir/ritonavir and ursodeoxycholic acid on reducing complications after cardiac surgery during covid-19 pandemics (the pep trial) is a multicenter, randomized controlled trial. The aim of the pep trial is to investigate whether prophylactic use of nirmatrelvir/ritonavir and ursodeoxycholic could reduce complications after cardiac surgery.
Levosimendan, a drug with inotropic, vasodilatory and myocardial protective properties, has been proposed for the prevention and treatment of postoperative low cardiac output syndrome in cardiac surgery. Despite preliminary studies with promising results, large randomized controlled trials aimed at demonstrating the benefits of levosimendan did not show superiority over placebo in this indication. However, in these studies, the infusion was neither performed at the maximum dosage nor during the 24 hours preceding the surgery, but mainly at the very beginning of the operation. However, post hoc analyses showed a reduction in mortality and in the occurrence of low cardiac output syndrome in the subgroup of patients who had undergone isolated coronary artery bypass grafting, in contrast to those who had undergone valvular or combined surgery. Another recent study suggests that under similar conditions, preconditioning with levosimendan started 48 hours before surgery reduces the length of stay in intensive care and the average cost of hospitalization. There are no formal recommendations on the prophylactic use of levosimendan in cardiac surgery for heart failure patients with impaired LVAS. However, the France-Levo registry, a multicenter observational study requested by the HAS, has shown that in real practice there is a place for preconditioning with levosimendan, which is used in this indication for 7% of the patients in the registry. The Cardiovascular Surgery and Transplantation Department of the Nancy Brabois University Hospital, which actively participated in the France-Levo registry, is one of the cardiac surgery centers that uses this practice, as is the University Hospital of Rouen. It is interesting to be able to evaluate retrospectively whether levosimendan preconditioning has a positive impact on the postoperative prognosis of patients and more particularly on the reduction of the length of stay in critical care and in hospital compared to standard management.
The use of Patient Reported Outcomes (PROs) in anaesthesia provides a measure of the patient's quality of postoperative recovery based on his/her own experience. The Quality-Of-Recovery-15 (QoR-15) is a widely used questionnaire which has never been validated in cardiac surgery patients. This study aimed at validating the French version of the QoR-15 scale in a cohort of cardiac surgical patients. The QoR-15 scale would have similar psychometric properties and interpretability in assessing postoperative recovery in this population than in general surgery patients.
Single blind feasibility trial using a binary 'traffic light' design to evaluate the feasibility of injecting normal physiological saline into the atria of patients at the time of clinically indicated open chest cardiac surgery.
This randomized controlled trial is to assess the effects of perioperative dapagliflozin on type 2 diabetic patients undergoing cardiac surgery
The proposed research is an important extension of an ongoing perioperative personalized analgesia and intravenous opioid pharmacogenetic research. This research focuses on two of the most commonly used oral opioid analgesics, oxycodone, and methadone in elderly adults undergoing cardiac surgery.
The exponential growth in plastic production/use translates into a parallel increase in environmental plastic waste, which is constantly degraded into microplastics and nanoplastics. Information on the effects of microplastics on human health is still preliminary. Cardiac surgery patients is a population high exposed to plastics. This observational study will obtain biological samples of cardiac surgery patients as a reference and vulnerable group of individuals highly exposed to microplastics and potentially more susceptible. The objective of this research is to be able to detect microplastics on blood and operation samples of cardiac surgery patients as well as their potential genotoxic and immunological damage.
Multi-centre, triple-blinded (patients, physicians, investigators), parallel-group, balanced (1:1), stratified (male-female 50-50), randomized, controlled (placebo), phase IV clinical trial to investigate the potential of preoperative initiation (from day 1 before surgery) and perioperative continuation (until day 2 after surgery) of the SGLT2 inhibitor dapagliflozin 10 mg once daily to prevent AKI according to the KDIGO criteria (an increase in serum creatinine by 0.3 mg/dl (26.5 mmol/l) within 48 hours; or an increase in serum creatinine to 1.5 times baseline, within 7 days; or a urine output <0.5 ml/kg/h for >6 hours) in adult (>18 years old) patients undergoing cardiopulmonary bypass surgery.
Renal resistive index (RRI) is calculated from ultrasonographic Doppler measurements of flow velocities in intraparenchymal renal arteries. Normal values are around 0.60, and 0.70 is considered the upper normal threshold in adults. Both preoperative and postoperative elevation of RRI has shown promise in early detection of AKI after cardiac surgery. Further, elevated RRI before coronary angiography is associated with an increased risk of cardiovascular complications up to 1 year after the procedure. The role of preoperative RRI in predicting long-term renal and cardiovascular complications after elective surgery is however not known. The aim of this study is to assess the role of preoperative RRI to predict the risk of persistent renal dysfunction as well as renal- and cardiovascular complications up to 5 years after surgery.
