Filter by:Acute respiratory failure (ARF) is a frequent reason for consulting in the Emergency Department (ED) and one of the major clinical problems prompting admission in intensive care unit. In the ED, evaluation of an ARF is mainly based on clinical examination and frontal chest x-ray performed to the patient bedside. This practice has a limited diagnostic capacity due to a lack of specificity of clinical and radiological semiology, especially in the polypathological patient. Thoracic ultrasonography provides morphological information regrouped as a syndrome (interstitial syndrome, alveolar condensation, pneumothorax) and allows the identification of pleural effusions (PE). The PE diagnosis is easy, quick, and relies on two-dimensional ultrasound imaging. Compared to CT scan, which remains the reference examination although ill-suited in the context of emergency, thoracic ultrasonography has a sensitivity and specificity greater than 90% for pleural liquid (PL) diagnosis. In addition, thoracic ultrasonography is used to assess the volume of PL, determine its nature and guide the pleural puncture with higher performance than chest x-ray. The semi-quantitative evaluation of PEs has been validated in patients with mechanical ventilation hospitalized in intensive care unit. On the other hand, few data on the prevalence and quantification of PL for hospitalized patients in ED for an ARF are currently available. Thus, the objective of this study is to evaluate the prevalence and severity of the PL identified by thoracic ultrasonography in patients admitted to the ED for an ARF by emergency physicians with ultrasound skills recommended by the French Society of Emergency Medicine.
Acute Respiratory Distress Syndrome (ARDS) is associated with a mortality rate of 30 - 45 % and required invasive mechanical ventilation (MV) in almost 85 % of patients[1]. During controlled MV, driving pressure (i.e., the difference between end-inspiratory and end-expiratory airway pressure) depends of both tidal volume and respiratory system compliance. Either excessive tidal volume or reduced lung aeration may increase the driving pressure. ARDS patients receiving tidal volume of 6 ml/kg predicted body weight (PBW) and having a day-1 driving pressure ≥ 14 cmH2O have an increased risk of death in the hospital[2]. Seemly, in the LUNG SAFE observational cohort, ARDS patients having a day-1 driving pressure < 11 cmH2O had the lowest risk of death in the hospital[1]. Hence, driving pressure acts as a major contributor of mortality in ARDS, and probably reflects excessive regional lung distension resulting in pro-inflammatory and fibrotic biological processes. Whether decreasing the driving pressure by an intervention change mortality remains an hypothesis; but one of means is to decrease the tidal volume from 6 to 4 ml/ kg predicted body weight (PBW). However, this strategy promotes hypercarbia, at constant respiratory rate, by decreasing the alveolar ventilation. In this setting, implementing an extracorporeal CO2 removal (ECCO2R) therapy prevents from hypercarbia. A number of low-flow ECCO2R devices are now available and some of those use renal replacement therapy (RRT) platform. The investigators previously reported that combining a membrane oxygenator (0.65 m²) within a hemofiltration circuit provides efficacious low flow ECCO2R and blood purification in patients presenting with both ARDS and Acute Kidney injury[3]. This study aims to investigate the efficacy of an original ECCO2R system combining a 0.67 m² membrane oxygenator (Lilliput 2, SORIN) inserted within a specific circuit (HP-X, BAXTER) and mounted on a RRT monitor (PrismafleX, BAXTER). Such a therapy only aims to provide decarboxylation but not blood purification and has the huge advantage to be potentially implemented in most ICUs without requiring a specific ECCO2R device. The study will consist in three periods: - The first period will address the efficacy of this original ECCO2R system at tidal volume of 6 and 4 ml/kg PBW using an off-on-off design. - The second part will investigate the effect of varying the sweep gas flow (0-2-4-6-8-10 l/min) and the mixture of the sweep gas (Air/O2) on the CO2 removal rate. - The third part will compare three ventilatory strategies applied in a crossover design: 1. Minimal distension: Tidal volume 4 ml/kg PBW and positive end-expiratory pressure (PEEP) based on the ARDSNet PEEP/FiO2 table (ARMA). 2. Maximal recruitment: 4 ml/kg PBW and PEEP adjusted to maintain a plateau pressure between 23 - 25 cmH2O. 3. Standard: Tidal volume 6 ml/kg and PEEP based on the ARDSNet PEEP/FiO2 table (ARMA).
Unresolved ARDS is defined by the persistence of ARDS criteria at the end of the first week of evolution despite an appropriate treatment of the cause of ARDS. A persistent ARDS is associated with an increased mortality and prolonged lengths of mechanical ventilation, ICU stay and hospitalization. Persistent ARDS is characterized by ongoing inflammation, parenchymal-cell proliferation, and fibroproliferation leading to disordered deposition of collagen. All of these pathways may be responsive to corticosteroid therapy. Only two randomized controlled double-blinded trials assessed the use of corticosteroids for persistent ARDS. In 24 patients, Meduri et al. reported an improvement of lung function and survival (1). In 180 patients, Steinberg et al showed no effect of corticosteroids on survival (2). A lower risk of death was observed when corticosteroids were started before 14 days after the onset of ARDS (2). Alveolar procollagen III is validated as a biomarker of active fibroproliferation. Alveolar procollagen III > 9 µg/L is associated to fibroproliferation (3). As mortality was lower in patients who received corticosteroids while presenting a high alveolar level of procollagen III on inclusion, Steinberg et al. showed that patients presenting with a low level of procollagen III and treated with corticosteroids had an increased risk of death (2). Investigatores hypothesize that the use of procollagen III could improve personalized decision-making regarding steroid treatment in patients presenting with persistent ARDS. The future of anti-fibrotic treatment, including corticosteroids, in persistent ARDS might propose to individualize the therapy according to the presence of an active fibroproliferative phase (precision or personalized medicine).
The present study will mainly aim at investigating the safety, tolerability and efficacy of different escalating single doses administration of nebulised Curosurf®, in preterm neonates with RDS (Respiratory Distress Syndrome) during nCPAP.
The purpose of this study is to determine if a repeat course of betamethasone given to pregnant women with preterm premature rupture of membranes (PPROM) will decrease the infant's length of stay in the neonatal intensive care unit (NICU) and the overall neonatal morbidity associated with this condition.
Bleeding complications and thromboembolic complications are frequent during extracorporeal membrane oxygenation (ECMO). Retrospective data suggest that platelet inhibition using prostaglandins, in this case PGE1, may reduce thromboembolic complications without increasing the bleeding risk. This randomized, double-blind trial aims to investigate the effects of PGE1 on bleeding risk, thromboembolic complications and the function of the ECMO.
This study compared the administration of porcine surfactant (poractant alfa, Curosurf®) through a less invasive method (LISA), using a thin catheter, CHF 6440 (LISACATH®), during non-invasive ventilation (CPAP, NIPPV, BiPAP) with an approved conventional surfactant administration during invasive ventilation followed by rapid extubation in terms of short term and mid-term safety and efficacy in spontaneously breathing preterm neonates who have clinical signs of respiratory distress syndrome (RDS).
This study is to evaluate the safety and tolerability of lucinactant for inhalation, administered as an aerosol in up to four escalating doses to preterm neonates 26 to 28 weeks gestational age who are receiving nCPAP for RDS compared to neonates receiving nCPAP alone.
Compare ventilation parameters in Adaptative Support Ventilation mode to conventional mode, on intubated, ventilated and sedated patients, during their secondary transfer from an hospital to another, by a SMUR team.
In this study, newborn babies with respiratory distress syndrome (RDS), receiving oxygen via nasal continuous airway pressure (CPAP) modalities, and needing surfactant treatment will be randomized to standard delivery of surfactant via and endotracheal tube airway (inserted after pre-medication for pain with a short-acting narcotic), or to surfactant delivery via laryngeal mask airway (LMA). The intent is to remove the airways and return babies to non-invasive CPAP support, after surfactant is given. The primary outcome measure is the rate of failure of initial surfactant therapy. Standardized failure criteria are reached: a) early, if the baby is unable to be placed back on non-invasive CPAP (i.e., needs tracheal intubation and mechanical ventilation) or, b) late, if the baby requires ventilation, retreatment with surfactant within 8 hours or more than 2 doses of surfactant. The objective of this protocol is to reduce the need for endotracheal intubation and mechanical ventilation in preterm neonates with RDS needing rescue surfactant therapy by instilling surfactant though an LMA, while achieving comparable efficacy of surfactant treatment. The hypothesis is that surfactant treatment through an LMA will decrease the proportion of babies with RDS who require mechanical ventilation or subsequent intubation, when compared to standard surfactant treatment following endotracheal intubation with sedation.
