Filter by:Preoperative anemia, bleeding and transfusions have been recognized as a "Deadly triad" in cardiac surgery associated with an increased morbidity,mortality, and costs related. Thus strategies to reduce unnecessary RBC transfusions and to optimize preoperative anemia must be developed .The study evaluate an individual blood conservation strategy based on patient blood management bundles in cardiac surgery patients: optimisation perioperative hemoglobin level by erythropoietin and ferric carboxymaltose (Ferinject) associated with the use of ScV02 to guide perioperative erythrocyte transfusion.
This study will investigate the potential of guiding remifentanil analgesia during cardiac and vascular surgery in moderate to high risk patients requiring general anesthesia.
Age is no longer an absolute contraindication to cardiac surgery therefore there is often need for combined interventions (double valve repair/replacement, or coronary artery bypass graft and valve repair/replacement) with relative prolongation of cardiopulmonary bypass time. Prolonged cardiopulmonary bypass use causes an increase in the inflammatory response, and on the other a need for blood reinfusion and therefore lipid microemboli from the operative field. The clinical consequences for patients are post-operative delirium and post-operative cognitive impairment. These two neurological complications involve up to 45% of elderly patients undergoing cardiac surgery and have a significant impact on quality of life, hospitalization and mortality in the short and long term. The Remowell 2 oxygenator system has demonstrated in preliminary studies that, compared to the gold standard Inspire oxygenator, it can guarantee a significant reduction of hemodilution, inflammatory systemic response and embolization of lipid microemboli and leukocytes. In light of these considerations, it is possible to formulate the hypothesis that the use of the Remowell 2 device can contribute to significantly reducing the onset of post-operative delirium and cognitive impairment. The present study is designed to validate this hypothesis in a randomized controlled scenario.
This study will assess whether non-pharmacological interventions by a comfort coach affect the amount of opioid pain medication used, as well as perceived physical pain and emotional anxiety and healthcare utilization for adult cardiac surgery patients. Participants that are eligible for the study will be randomized to the comfort coach arm or standard of care. Both groups will complete surveys at the specific time frames in order to compare their outcomes. The study hypothesis is that there will be a decrease in opioid use in the intervention group compared to the standard of care arm during the 90-day perioperative course, as well as a decrease in pain and anxiety along with a lower composite outcome of healthcare utilization.
The aim of this study is to investigate the efficacy of early postoperative enteral immunonutrition on immune response and outcomes in the low operative risk cardiac surgery population with low phase angle value measured by the bioelectrical impedance analysis.
The aim of this study is to evaluate whether the application of glutamine versus control in patients with high risk for AKI identified by biomarkers can reduce kidney damage after cardiac surgery.
Weaning from mechanical ventilation represents 50% of the time spent under mechanical ventilation (1). The risk factors identified in the failure to wean from mechanical ventilation are: - left heart dysfunction with LVEF < 30%. - an ineffective cough - presence of resuscitation neuromyopathy - mechanical ventilation time >7 days - presence of a delirium - age >65 years old - abundant bronchial secretion - presence of underlying lung pathology An ineffective cough is found in 40% of patients requiring reintubation. However, cough assessment is most often approximate, based on a subjective assessment of cough strength by asking the patient to cough spontaneously on his or her tube). The objective evaluation of cough is based on the measurement of the peak expiratory flow rate at cough, commonly referred to as peak expiratory flow rate at cough (PEFD), the patient is asked to take a deep breath and then cough as hard as possible. Subjective cough assessment does not predict the occurrence of ventilatory withdrawal failure. Conversely, all studies that objectively assessed the strength of cough before extubation by measuring the PEFD found a significant association with the outcome of extubation: a low PEFD increases the risk of extubation failure by a factor of 5 to 9. The investigators hypothesize that the increase in parietal abdominal muscle contraction obtained by using a non-invasive ultrasound method indicates an effective cough. Conversely, an ineffective cough can be detected by this simple ultrasound criterion, which can be performed at the patient's bedside and extrapolated to all intensive care units equipped with an ultrasound scanner. This evaluation will be carried out before extubation: during the spontaneous ventilation test on a tube in a half-seated position (>45°) and within 24 hours after extubation.
The purpose of the study is to validate a ventricular pacing test as a predictor of preload dependency in post cardiac surgery patients.
Evaluation of the prognosis value of sST2 dosed before cardiac surgery on prognosis of long terme prognosis after cardiac surgery. The patients where initialy recruted for another cohort named micro-SIRS and inflammation but the gaved their consent to analyse the blood samples for other studies
