Intensive Care Unit Syndrome

This research helps to close an important gap in the provision of care to ICU families and introduces a structured and accessible psychological intervention to family caregivers of long-stay ICU patients. The findings are expected to contribute to the integration of stress management training in family-centered nursing practices and contribute to improved psychological well-being of the caregivers of families in intensive care settings.

Paracetamol is commonly used in case of pain or fever. Few previously clinical studies has highlighted an arterial hypotension linked to intravenous administration of paracetamol. Currently, fewer data are available on the link of intravenous administration of paracetamol and effects on arterial tension. The aim of this study is to describe the frequency of occurrence of significative arterial hypotension within one hour following intravenous or per os administration of paracetamol . Other factors who can be associated to occurence of significative arterial hypotension will be also observe (for example age, weight, pain, vasopressor dosage or sedative...)

The goal of this observational study is to learn about the priorities of patients admitted to intensive care units (ICUs) who have a life-threatening condition, as well as the priorities assumed by their designated relatives and healthcare professionals (nurses, nursing assistants, ICU physicians, and general practitioners).

The risk associated with arterial hypotension during anesthesia for intensive care sedation has been demonstrated, but the threshold at which consequences for perfusion of one or more organs appear varies according to the mechanism of hypotension, associated abnormalities (HR, cardiac output and oxygen transport) and the patient's terrain. Currently, a mean arterial pressure greater than 60 mm Hg (1) and a reduction of less than 30-50% from the value measured before sedation are commonly used to ensure good perfusion of all organs. In intensive care, it is recommended to maintain a MAP between 60 and 70 mmHg and a Cerebral Perfusion Pressure (CPP) \> 50 mmHg for neurocompromised patients with Intra Cranial pressure (ICP) measure. Normally, cerebral blood flow is self-regulated, allowing adaptation of cerebral blood flow to oxygen requirements at different levels of high and low blood pressure. However, this protective mechanism may fail for a degree of hypotension that depends on several factors such as the age or vascular status of the patient. The aim of the study is to measure non-invasively, easily and reliably the variations of cerebral perfusion in patients with or without cardiovascular risk factors during controlled variations performed during routine care to set the blood pressure level within the recommended safety standards during sedation in intensive care unit. What is the tolerable target BP level for a patient under continuous sedation in the ICU? Is there a simple and non-invasive way to measure the level of cerebral blood flow autoregulation and especially the adequacy of the brain's oxygen requirements?

To observe and identify determinants of recovery from intensive care unit-acquired weakness (ICUAW) following a severe cardiorespiratory failure requiring extra-corporeal membrane oxygenation (ECMO). Additionally, to discover the effects of ICUAW on physical function and health-related quality of life (HRQoL) after critical illness. CLEVERER is a clinical observational pilot study.

This project intends to track and evaluate whether post-ICU syndrome will occur 7 days, 1 month, 3 months and 6 months after ICU patients are transferred out of the ICU through a longitudinal study, apply the latent category growth model to identify different trajectory patterns of post-ICU syndrome in critically ill patients, and use modern machine learning models to build an early warning model of the trajectory patterns of post-ICU syndrome.

Anxiety and discomfort generated by repeated medical cares and invasive procedures can induce cognitive disorders in critical illness survivors as post-traumatic stress disorder. For this reason, managing patients' anxiety is particularly important in the intensive care unit. Physicians have recently started using immersive virtual reality (VR), based on real-time interaction with an artificial 360° immersive world, as an adjunctive non-invasive and non-pharmacological anxiolysis technique. The purpose of this project is to assess the virtual reality stimulation to reduce anxiety in Intensive Care Unit (ICU) patients.
