Active clinical trials for "Critical Illness"

This work aims to describe the characteristics and methods of management of patients suffering from a solid tumor treated with immunotherapy admitted to intensive care.

This prospective observational cohort study will investigate the impact of a bundle of nine preventive measures (Assessment, prevention and management of pain; spontaneous awaking trial; spontaneous breathing trial; choice of sedation and analgesia; delirium assessment, prevention and management; early mobility; family communication and ICU Diary) on the incidence and severity of Post-Intensive Care Syndrome (PICS) and clinical outcomes in critically ill patients

Primary objective The objective of this study is to compare anti-Xa levels obtained with a standard high dose thrombosis prophylaxis in COVID-19 intensive care-patients compared with anti-Xa levels obtained with a normal dose thrombosis prophylaxis in non-COVID-19 intensive care patients. Secondary objectives To determine the incidence of anti Xa levels out of range of the established target anti Xa level in both groups. To determine the influence of relevant co-variates on the anti-Xa level in the COVID-19 and non-COVID-19 group.

To determine whether high-protein (24% of total calorie from protein) enteral nutrition of immune modulating nutrients (eg, ω-3 fatty acids and antioxidants) enriched with β-glucan stimulates immune functions compared with standard enteral nutrition (control: 20% of total calorie from protein) or high-protein (24% of total calorie from protein) enteral nutrition of immune modulating nutrients without β-glucan in critically ill patients.

Prospective observational study designed to implement a daily monitoring of microcirculation and tissue oxygenation in all critically ill patients admitted to the ICU in the period of nine months, in order to assess the prevalence of microvascular perfusion abnormalities and their relation to: outcomes, underlying disease, hospital stay, clinical-laboratory and hemodynamic parameters commonly measured, indices of clinical severity and predictors of mortality , therapeutic interventions that are part of routine clinical practice (fluids, sedation, vasopressors, inotropes, anticoagulants, renal replacement therapy, blood transfusion). The study also includes the evaluation of sublingual microcirculation and tissue oxygenation in 30 healthy volunteers to compare normal and pathological conditions. Within the first 12 hours after admission to ICU and every 24 hours for the duration of hospitalization, the following evaluations will be made: -study of sublingual microcirculation using sidestream dark field (SDF) imaging, muscle tissue oxygenation using near infrared spectroscopy (NIRS). The data will be analyzed to test correlation between the outcome of patients admitted in ICU and microcirculatory parameters.

The aim of the proposed study is to better understand the epidemiology of, risk factors for and consequences of critical illness leading to improvements in the risk models used to underpin national clinical audits for adult general critical care, cardiothoracic critical care and in-hospital cardiac arrest using data linkage with other routinely collected data sources.

This study compared two methods of insulin infusion by syringe pumps to assess the impact of medical devices on the glycaemic variability in patients under IIT in ICU. The main objective of the study was to show the superiority of the infusion system which permitted to dedicate a line for the insulin administration on the "standard" installation in terms of control of glycaemic variability.

Malnutrition is a frequent problem in critically ill patients that is associated with detrimental clinical outcomes. To provide adequate nutritional support, current studies focused mostly on the choice of delivery timing, formula selection and the route of administration, little attention was paid to malnutrition related to exocrine pancreatic insufficiency (EPI). In fact, malnutrition is also a major consequence of pancreatic exocrine insufficiency and pancreatic damage is commonly observed in critically ill patients without prior pancreatic diseases. Hence, EPI associated malnutrition should be concerned due to the high prevalence of pancreatic damage in critically ill patients. The aims of this study is to evaluate the incidence of EPI in critically ill adult patients and explore its potential risk factors. Moreover, the efficacy of pancreatic enzyme supplementation therapy on malnutrition in ICU patients with specific clinical characteristics will be investigated.

For critically ill patients, it is important to know when to liberate them from mechanical ventilation (the removal of breathing or endotracheal tube or extubation) and weaning (the progressive decrease of the amount of support that a patient receives from the mechanical ventilation). It is well recognized that prolonged ventilation and weaning harms patients and introduces significant increased costs to the health care system. The investigators objective is to improve the safety of removal of life support in critically ill patients by harnessing information from two new technologies; NM3 and Nexus device. In particular, the investigators are interested in the patterns of variation of respiratory and cardiac signals from the NM3 device, as well as monitor skin conductance with the Nexus device. The combination of these measures has not yet been investigated to date, and could represent a novel set of measures that can be used to help physicians better manage critically ill patients. The current standard of care dictates that once a patient is considered as a candidate for withdrawal from ventilation, a spontaneous breathing trial (SBTs) is performed, where the degree of ventilator support is decreased, and their response is observed to help predict if they will tolerate extubation. Health is associated with a high degree of variation of physiologic parameters such as heart rate and respiratory rate, and illness & stress are associated with a loss of variability. The analysis of variability of biological signals measures the degree of fluctuations present over time. Previous studies have demonstrated that changes in variability (generally decreases) are observed in illness states, and the degree of this change correlates with illness severity. Several studies have reported that reduced heart or respiratory rate variability (HRV or RRV) during SBTs is associated with extubation failure. Until recently, variability analysis has traditionally been done only on heart rate (HRV), derived from analyzing beat-to-beat intervals from the ubiquitous electrocardiogram (ECG). The investigators aim to apply variability analysis to the respiratory and cardiac signals which represent a rich novel set of muti-organ variability measures whose utility in managing extubation and ventilator weaning has not been investigated to date.
