Filter by: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.
The purpose of this study has two major goals: 1) to measure the amount of two specific hormones interleukin (IL)-10 and interleukin (IL)-12p70 in mucous and blood; and 2) compare the hormone levels in two specific areas of the lung called the trachea (upper airway) and the bronchioles (lower airway). The hormones IL-10 and IL-12p70 are cytokines, special hormones cells use to communicate with each other during inflammation or infection. Cytokines can be measured in mucous and blood. The balance of one cytokine compared to another help doctors to understand how people respond differently to infection. Unfortunately, the amount of IL-10 and IL-12p70 is not known in children, especially children with a lung infection. In addition, we do not know if the balance of these cytokines differ in various regions of the lung. We believe the balance of IL-10 and IL-12p70 is similar whether measured in the upper or lower airways.
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 is a multicenter, prospective, randomized, open-label study which compared two ventilation modes: spontaneous NAVA mode and spontaneous breathing with IPS mode (the latter is considered as the reference ventilatory mode) in patients admitted to the ICU for acute respiratory failure and ventilated with an endotracheal tube. NAVA mode allows to minimize patient-ventilator disharmony with acceptable tolerance and to preserve spontaneous ventilation.
Examination of serial muscle ultrasounds and muscle sampling within the population of ICU patients who require mechanical ventilation for acute respiratory failure, will lead to the ability of investigators to link specific baseline comorbidities, drugs, or fluid administrations, to the onset and duration of architectural changes within muscle and correlate ultimately with muscle function. With this study, we will be better able to understand the relationships between the pattern of resolution of the muscle architectural abnormalities within the context of multiple other clinical abnormalities and therapies present and rendered to ICU patients.
Acute respiratory failure may occur early in the postoperative course, requiring endotracheal intubation and mechanical ventilation in selected patients, thus increasing morbidity and mortality and prolonging intensive care unit (ICU) and hospital stay.We will perform a multicenter, prospective, randomized clinical trial to compare the efficacy of non invasive ventilation (NIV) which associated pressure support ventilation (PSV: 5 to 15 cmH2O) and positive end expiratory pressure (PEEP: 5 to 10 cmH2O) with standard oxygen therapy in the treatment of postoperative acute respiratory failure. We also set out to examine the hypothesis that early application of NIV may prevent intubation and mechanical ventilation in patients who develop acute respiratory failure after abdominal surgery.
The present study aims to evaluate the impact of a weaning strategy based on identification of early signs of respiratory distress by lung ultrasound and the consequent implementation of a "clinical optimization" protocol as compared to usual care.
The purpose of this study is to assess whether Optiflow, a high-flow humidified oxygen delivery system, is superior to standard oxygen therapy during breaks off noninvasive ventilation in patients affected by acute respiratory failure and in respiratory distress. The investigators anticipate that the Optiflow will provide oxygen more effectively, be more comfortable and permit longer breaks off NIV, shortening the total duration of NIV.
Rationale : Electric muscle stimulation reduced critical-illness related weakness in patients with severe sepsis and septic shock. But optimal protocol of the stimulation in unknown. Hypothesis: Focal muscle contraction may improved the muscle power and have systemic anti-inflammatory via cytokine secretion . The difference of electricity used in upper limb or lower limb stimulation may lead to different effect. Study design: Stratified randomized parallel control study, comparing Biceps, Quadriceps electric muscle stimulation vs. non-stimulation group. Participant: adult patients with severe sepsis and acute respiratory failure requiring mechanical ventilation. Intervention: daily stimulation of bilateral Biceps or Quadriceps by programmed electric devices 32 minutes, 5 days/week Outcome: 1. Primary outcome: Ventilator-dependent days 2. Secondary outcome: change of hand drip muscle power/interleukin-1b/interleukin-6/interleukin-8/TNF-alpha
