Filter by:The aim of this study is to evaluate the performance, the tolerability and the efficacy on gas-exchange of different CPAP (Continuous Positive Airway Pressure) systems.
The purpose of the study is to determine the efficacy and safety of dexmedetomidine during Non-invasive positive pressure ventilation (NPPV) for patients with acute respiratory failure compared to standard analgesic/sedation practices
This is a study to determine the testosterone serum levels in male patient with acute respiratory failure requiring mechanical ventilation. The objective is to determine if low levels exist in this population and if it correlates with length of mechanical ventilation. Hypothesis: Serum testosterone levels in mechanically ventilated male patients are significantly decreased from normal levels and correlate with disease severity and outcomes.
Patients with failed extubation stay significantly longer in an intensive care unit (ICU) and have a higher mortality rate, than those intubated successfully. Reintubation is associated with life-threatening complications and a poor prognosis. Functional respiratory tests are frequently used as weaning parameters, however, they are not accurate enough to predict extubation failure. The incidence of swallowing dysfunction is underestimated, mainly among patients whose intubation lasts longer than 48 h.We previously observed that the assessment of the swallowing function and oropharyngeal motricity, conducted by the physiotherapist before extubation could be helpful for making decisions to extubate patients intubated for over 6 days. The objective of this study is to validate a scale previously devised and used for physiotherapist bedside evaluation of the swallowing function and oropharyngeal motricity, among patients intubated for over 6 days, to determine whether this scale is a good predictor of airway secretion-related extubation failure.Expected results : to validate a scale previously devised called " physiotherapist evaluation of the swallowing function and oropharyngeal motricity before extubation" by the mean of a multicentric study. In our hypothesis the clinical parameters studied could be predictive of extubation failure. Then, this evaluation could help the medical decision in the choice of the good time for extubation. The final objective is to lower the mortality related to extubation failure.
To compare the rapid shallow breathing index (RSBI) values, the incidence of adverse reactions, and the predictive accuracy measured under 5 different ventilator strategies in the same patient group.
Twenty per cent of the intensive care patients mechanically ventilated suffer from chronic obstructive pulmonary disease (COPD). These patients stay longer in Intensive Care which is more costly and they are more prone to nosocomial infection.In addition, they are longer bedridden and they develop muscular weakness.Prolonged inactivity results in respiratory and skeletal muscle weakness which curtails simple daily activity.The principal purpose of this study is to compare two types of muscular rehabilitation (electrical stimulation of the thigh and/or cycloergometer training) to classic passive mobilization of the leg.The second purpose is to analyse the effects of each type of rehabilitation on muscular fiber (structural and functional analysis) by muscular biopsies.Two hundred forty COPD patients admitted in the intensive care unit for acute respiratory failure will be randomized in 4: 1 fashion to receive passive mobilization of the legs(group 1, n=60), electrical stimulation of the thigh (group 2, n=60), cycloergometer training (group 3, n=60) or electrical stimulation of the thigh and cycloergometer training(group 4, n=60).The rehabilitation program will last 4 weeks with 5 sessions per week.In each group of patients, muscular biopsies will be done under local anaesthesia at the beginning and end of the rehabilitation programme and when they are discharged from the service.
The efficacy of NIMV to treat HARF has been widely demonstrated. However, in most of the studies performed in ICUs and in another facilities the mean age of the patients is usually less than 70 years. A multicentric, randomized-controlled trial conduced in a group of "ELDERLY" patients with the mean age higher than 76 years, to compare the use of NIMV with Standard Medical Treatment (SMT) in the treatment of an episode of Acute Hypercapnic Respiratory Failure.
Most patients admitted to intensive care units require mechanical ventilation. Weaning from assisted/controlled ventilation begins when we recognize that the patient has recovered adeguately from acute respiratory failure. If weaning is delayed, costs are increased, as are the risks of nosocomial pneumonia, cardiac-associated morbility, and death. On the other hand, weaning too soon often results in reintubation, which is associated with complications similar to those of prolonged ventilation. The aim of this trial is to establish an evidence-based approach to weaning and to determine when a patient is ready to be weaned from mechanical ventilation, and what is the best weaning technique.
Current American-European Consensus Conference (AECC) definitions for ALI and ARDS are inadequate for inclusion into clinical trials due to the lack of standardization for measuring the oxygenation defect. We questioned whether an early assessment of oxygenation on specific ventilator settings would identify patients with established ARDS (persisting over 24h).
The main objective of the study is to evaluate the predictive factors of the endothelial function to the waning of an acute exacerbation in COPD. It will act to do a multivariate analysis to determine the respective weight of the parameters of the systemic inflammation, of the oxidative stress of the functional respiratory parameters and then functional respiratory parameters. In exacerbated Chronic Obstructive Pulmonary Disease (COPD) patients, there is augmentation of hypoxia and the obstructive ventilatory disorders is more important. This is correlated with an increase in C-reactive Protein (CRP) and of inflammatory cytokines and oxidative stress. It has been demonstrated that there is an endothelial dysfunction in answer to hypoxia. Since the exacerbated COPD patients are hypoxic in most cases , we suppose they have an endothelial dysfunction during exacerbation. So we think we will find an augmentation of vascular resistances ,shown by a peripheral arterial tone too high. And this, certainly, play a part in physiopathology of the COPD exacerbation.
