Intensive Care

Most patients admitted to intensive care after severe trauma, high-risk surgery, or acute respiratory distress are frequently characterized by significant initial inflammation accompanied by a compensatory anti-inflammatory response, which can lead to profound post-aggressive immunosuppression. This immunosuppression is associated with an increased risk of nosocomial infections, viral reactivations, prolonged ICU stays, and ultimately, increased mortality. Consequently, immunostimulation with agents such as interferon gamma (IFN-γ) has been proposed as a means to restore immune defense in the most severe patients. However, in a recent study conducted on mechanically ventilated patients with acute organ failure, treatment with interferon gamma-1b compared to placebo did not significantly reduce the incidence of nosocomial pneumonia or 28-day mortality and was even associated with an increase in severe side effects, leading to the premature termination of the trial. These results, along with previous studies, suggest that for IFN-γ to be effective, it must be targeted at patients who have reached the immunosuppressive phase. In the absence of evident clinical signs, the use of biomarkers could guide clinicians in identifying the appropriate patients and the optimal timing for this therapy. In a recent monocentric study, they evaluated a new automated IFN-γ assay on a cohort of 22 septic patients to monitor T lymphocyte functionality independently of antigen. As expected, the results showed a marked decrease in IFN-γ release, which correlated with altered classical cellular parameters (CD8+ T cells, mHLA-DR). Since the test is performed using whole blood, requires no technician intervention, and provides results within four hours, this project propose to characterize the evolution of the immune status of a large cohort of ICU patients, including those with severe trauma, high-risk surgery, or acute respiratory distress syndrome.

An increasing amount of evidence from evidence-based medicine indicates that early rehabilitation intervention for patients receiving mechanical ventilation is safe and feasible, and can promote functional recovery and reduce hospital stay. However, the conscious state, respiratory function, and daily living activities of these patients after being discharged from the ICU vary greatly, and some patients do not show obvious benefits. How to identify which patients may have benefit from early rehabilitation is a key issue that needs to be addressed in critical care rehabilitation. This study aims to investigate the clinical data related to the disease of the ICU survivors who received mechanical ventilation as the research object, by collecting their clinical data when receiving early rehabilitation intervention, and constructing a clinical prediction model for the efficacy of early rehabilitation intervention in the ICU through the selection of optimal regression equation or machine learning algorithm. The application of this model can effectively determine whether ICU inpatients need early rehabilitation intervention, thereby reducing complication rates and improving their quality of life.

Oro-tracheal Intubation uses oro-pharyngeal lesions, impacting on the length and quality of the patient's hospital stay. There are no oral status assessment tools specifically adapted to orally intubated patients. It is therefore necessary to create a new tool for assessing the condition of the oral cavity, specific to oro-intubated patients in intensive care. The aim of the protocol is to evaluate the metrological performance of the newly-developed tool for assessing the state of the oral cavity in adult orally intubated intensive care patients.

This is a prospective, observational, monocentric, phase II (exploratory) cohort study aiming to describe the evolutionary profile of the initial volume of glucose distribution (IDVG) during the first four days of management of severely burned patient.

In intensive care, respiratory physiotherapy is an integral part of the daily care of patients under invasive mechanical ventilation. Its goals are to improve the clearance of bronchial secretions to allow for the resolution of atelectasis and alveolar recruitment, thereby enhancing respiratory mechanics and gas exchange. The most widespread technique in France is external expiratory compression of the chest. The effectiveness of this technique depends on the selection of patients (it seems to be more effective in patients with higher secretion levels) and on the practical implementation of the technique (favoring brief and vigorous compressions at the beginning of expiration). However, the effect of the artificial ventilator settings, particularly the ventilatory mode used during the respiratory physiotherapy session, has never been evaluated. The two most commonly used ventilatory modes worldwide are Volume Assist Control Ventilation (V-ACV) and pressure support ventilation (PSV). In this unit, respiratory physiotherapy under artificial ventilation is performed daily on patients with artificial ventilation with abundant secretions, regardless of the ventilatory mode.

ECMO (extracorporeal membrane oxygenation) is a life-saving device, used in intensive care to treat severe respiratory or cardiac failure. However, it carries a high risk of serious life-threatening bleeding. Bleeding complications have been attributed to coagulopathy triggered either by the underlying pathology or by the extracorporeal circuit itself, as well as excessive or inappropriate anticoagulation initiated to prevent thrombotic complications. The objective of this cohort is to confirm the interest of the evolution of D-dimers as a prognostic marker of serious bleeding events in patients on veno-venous (VV) or veno-arterial (VA) ECMO, and to determine the threshold.

In extracorporeal membrane oxygenation (ECMO), blood is drawn out of the body via tubes, oxygenated in an artificial lung; and then pumped back into the blood vessels. This allows the supply of oxygen-rich blood to the organs (brain, heart, lungs, kidneys, liver, intestines, etc.) to be maintained. Continuous monitoring of cardiac function and circulatory status (blood pressure, blood flow to organs) is very important in intensive care medicine in order to control the administration of circulation-supporting medication and infusions. Various devices are routinely used for this task. However, in the specific situation of ECMO treatment, the measurements of these devices could be affected due to the artificial circulation; outside the body. The purpose of this study is therefore to test the accuracy of different methods of circulation monitoring during ECMO treatment.

Intensive care medicine is vital in managing patients after cardiac surgery with endotracheal intubation，in order to provide extensive monitoring to assure clinical stabilization. During this time of recovery, sedation is frequently employed. However, prolonged sedation risks negative sequelae.At present,propofol, benzodiazepines, and dexmedetomidine are typical drugs used for sedation of patients in intensive care unit.Each has its own advantages and disadvantages.The investigators try to find near-ideal agents for sedation,characterized by good sedative effect,minimal adverse effects and rapid awakening facilitating earlier extubation.Remimazolam appeared to be an effective and safe sedative for short term sedation. Study participants were predicated on age (\> 18 years), admission following cardiac surgery, still mechanical ventilation within 48 hours,and prior informed consent.Participants were randomized to receive remimazolam besylate or propofol in a 1:1 ratio for sedation with a target sedation depth before extubation.Finally，the investigators will compare the sedation effect and safety between the 2 groups ，to prove if remimazolam is appropriate for sedation in patients after cardiac surgery in intensive care unit.

"Huede" AI Aided AKI Prediction Software, Acura AKI, uses machine learning algorithms to predict the risk of AKI within the next 24 hours and provide a ranking of feature importance. By using Acura AKI, physicians can assess the risk of AKI, focusing on high-risk patients to provide care decisions. This study will be conducted in a prospective randomized clinical trial in adult ICUs, implementing the Acura AKI system for predicting AKI. The study aims to determine whether early prediction and intervention using the Acura AKI system can improve the outcomes of critically ill patients with adverse kidney conditions. The study endpoint is to evaluate the cost-effectiveness of using Acura AKI, including the incidence of AKI, dialysis rates, mortality rates, length of hospital stay, and treatment costs.

Peripheral venous catheterization represents the preferential option for term or preterm infant care in order to start drug treatment or hydration, or perform anesthesia. However, the peripheral venous access is associated in approximately 50% of cases with a failure of the insertion on the first attempt in an emergency context. Using a micro-guide may facilitate the peripheral venous catheterization in newborns, by guiding the catheter in the vein and, thereby reduce the risk of transfixion of the vascular lumen.
