Filter by:ICU care of patients considered "palliative" but without contraindications to admission to intensive care, for whom a do-not intubate order decision was made upon admission represents a particular target for non-invasive oxygenation techniques. The benefits of non invasive ventilation (NIV) in this population are debated especially in cancer patients. The more recently used nasal humidified high flux canula oxygenation (HFNC) therapy may have benefits over NIV in these patients. It is supposed to have better tolerance and could allow better compliance and thus higher efficiency. These potential benefits are major for such a population for which tolerance and symptomatic relief are priority goals
This study proposes a novel early intervention combining Intravenous (IV) amino acids plus in-bed cycle ergometry exercise to improve physical outcomes in critically ill patients. The investigators hypothesize that this innovative approach will improve short-term physical functioning outcomes (primary outcome), as well as amino acid metabolism, body composition, and patient-reported outcomes at 6-month follow-up.
Over the last two decades, non-invasive ventilation (NIV) has been widely reported as an effective method to avoid the need of endotracheal intubation (ETI) and improve survival in the acute care setting. Given the risks associated with either premature NIV discontinuation or delays in NIV interruption, evaluating readiness to weaning from NIV is a critical challenge in patients with Acute Respiratory Failure (ARF). Up to date, bedside measurements used to predict NIV outcomes are extremely limited. NIV weaning as well as decision of ETI are mainly supported by clinical and physiologic parameters. More sophisticated techniques used to predict weaning outcome during spontaneous breathing trials have never achieved a bedside broad-spectrum use due to their invasiveness, the inconsistent results in demonstrating reproducible outcomes, the requirements of additional trainee personnel and complicated equipment, and the difficult application in awake and non-intubated patients. Recently, ultrasound has been used for the rapid assessment of diaphragm function in acutely ill patients. The advantages of the ultrasound in detecting diaphragm dysfunction as compared with other techniques are the less invasiveness, the avoidance of radiation hazards and the bedside feasibility. Direct imaging of changes in diaphragm thickening (DT) during spontaneous breathing may provide the assessment of both the muscle and the respiratory pump functioning. Indeed, DT has been correlated with the diaphragm strength and the muscle shortening. The volume of diaphragm muscle mass remains constant while it contracts. Consequently, as the muscle shortens it thickens itself and measurements of changes in such a thickening (DT) are inversely related to changes in diaphragm length. Studies in patients with diaphragm paralysis have confirmed the absence of DT. Moreover, since the diaphragm is the major muscle of inspiration, the presence of diaphragm shortening and contraction may predict successful extubation in patients who are invasively ventilated. The aim of the present study is to assess whether DT as measured by ultrasound may predict NIV outcome in patients with de-novo ARF admitted to the Emergency Department (ED).
Title: Reduced Unloading in NAVA Improves distribution of Ventilation in ICU patients. Objectives: 1. To investigate if NAVA targeted to moderate respiratory muscular unloading results in redistribution of ventilation to the dorsal regions of the lungs 2. To verify if the redistribution of ventilation translates to a better gas exchange and to a potentially lung protective ventilation strategy (lower airway pressures) 3. To verify the possibility to set NAVA at different levels of unloading, based on Neuro-Ventilatory Efficiency. Study Design: Randomised Crossover of Pressure Support and NAVA at different levels of unloading. Population: Adult Intubated patients at the Neurosurgical ICU, ventilated for more than 48h, in weaning phase from mechanical ventilation. Study duration: 2,5h Number of subjects: 12
Crystalloid solutions modify acid-base equilibrium according to their electrolyte composition. Moreover, it has been suggested that these alterations are generated by the difference between the solution strong ion difference (SID) and the plasma bicarbonate level. An increased risk of acute kidney injury and renal replacement therapy has been associated to the infusion of chloride rich crystalloids. This study aims to compare, in patients with acute respiratory failure undergoing ECMO support, the effects on acid-base status and renal function of crystalloids commonly employed for circuit priming to a balanced solution created with a SID equal to patients' bicarbonate level.
Determining the optimal Neurally Adjusted Ventilatory Assist (NAVA) level remains challenging, and several methods have been suggested. However none of them seems easily utilisable. Thus the investigators propose to test a way of NAVA level titration according to ventilator comfort.
In spontaneously breathing mechanically ventilated patients, the adequacy between the patient's demand and the level of respiratory support delivered by the ventilator is a major clinical issue. Neurally adjusted ventilator assist (NAVA) and proportional assist ventilation (PAV) have been developed to adapt the level of assistance to the patient's demand. These two modes have been compared to pressure support ventilation (PSV) but have not been compared to each other.
Neurally Adjusted Ventilatory Assist (NAVA) is a new form of partial support wherein the machine applies positive pressure throughout inspiration in proportion to the electrical activity of the diaphragm (EAdi), as assessed by trans-esophageal electromyography. To test the hypothesis that NAVA could provide better patient-ventilator synchrony during NIV delivered by nasal-facial mask as compared to conventional flow-triggered PSV in infants with Acute Respiratory Failure.
Energy expenditure (EE) in critically ill patients is highly variable depending on the initial severity of the disease and treatments. Clinicians need to measure EE by indirect calorimetry (IC) to optimize nutritional support. IC devices available on the market have insufficient accuracy for clinical and research use. A new IC is being developed to meet these needs. Objectives: Validation of a reliable and easy-to-use IC device. Primary objective: • Accuracy of EE measurements (kcal/d measured over 30 min) of the new and the reference IC devices in intubated ICU patients on mechanical ventilation Secondary objectives: - Accuracy of EE measurements in ICU patients of spontaneous breathing - Accuracy of EE measurement during ~30 min. vs. the sum of 6 periods of 60 min/12 hrs - Accuracy of EE measurements in ICU patients on non-invasive mechanical ventilation Design: Prospective, controlled, observational multicenter study. Subjects: 182 ICU patients.
This pilot study will be an observational no randomize study in which the NiNAVAped protocol will be applied solely to the NIV NAVA arm.
