Ultra-protective Ventilation Monitored by Electrical Impedance Tomography in Patients With Severe...

Severe ARDS

For ECMO supported patients with severe ARDS (acute respiratory distress syndrome), usual care include use of "ultraprotective" mechanical ventilation with tidal volume and pressure reductions that might ultimately enhance lung protection of patients with ARDS. Although very low tidal might also cause pulmonary derecruitment. The aim of this study is to monitor effects of very low tidal volume on regression of overdistension and derecruitment using electrical impedance tomography. Secondary aim is to describe the evolution of the optimal PEEP (Positive End Expiratory Pressure) during the decrease of the tidal volume

Enhanced Lung Protective Ventilation With ECCO2R During ARDS

ARDSHuman1 more

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: Minimal distension: Tidal volume 4 ml/kg PBW and positive end-expiratory pressure (PEEP) based on the ARDSNet PEEP/FiO2 table (ARMA). Maximal recruitment: 4 ml/kg PBW and PEEP adjusted to maintain a plateau pressure between 23 - 25 cmH2O. Standard: Tidal volume 6 ml/kg and PEEP based on the ARDSNet PEEP/FiO2 table (ARMA).

Acute Respiratory Distress SyndromeProne Position

Acute Respiratory Distress Syndrome (ARDS) is defined according to the Berlin definition (1) as diffuse lung damage occurring in patients with a predisposing risk factor. Positioning in the prone position (PP) has been shown to decrease mortality in patients with moderate to severe ARDS. However, this technique is not without deleterious effects such as ventilator-associated pneumonia, endotracheal tube obstruction, development of pressure ulcers, and increased workload for the caregivers. There are other positioning techniques such as the "upright" position, which simulates a relative verticality, which allows to increase the effects of the prone position and even in some patients to improve oxygenation without the PP in the acute phase of ARDS. However, given the revolution caused by the use of PP in ARDS patients, verticalization have not been studied in more details. Today, there is a bed on the market that allows patients to be truly upright without having to transfer them to a tilt table. The investigators believe that raising ARDS patients in the acute phase is safe and feasible in routine practice. In this research protocol comparing PP and verticalization in a crossover trial design in acute ARDS patients, the investigators want to show that this technique can be safe and feasible, with the same effects on oxygenation as PP.

Prone Positioning and Abdominal Binding on Lung and Muscle Protection in ARDS Patients During Spontaneous...

Acute Respiratory Distress SyndromeMechanical Ventilation Complication1 more

Ventilator-induced diaphragmatic dysfunction and intensive care unit (ICU)-acquired weakness are two consequences of prolonged mechanical ventilation and critical illness in patients with acute respiratory distress syndrome (ARDS). Both complicate the process of withdrawing mechanical ventilation, increase hospital mortality and cause chronic disability in survivors. During transition from controlled to spontaneous breathing, these complications of critical illness favor an abnormal respiratory pattern and recruit accessory respiratory muscles which may promote additional lung and muscle injury. The type of ventilatory support and positioning may affect the muscle dysfunction and patient-self-inflicted lung injury at spontaneous breathing onset. In that regard, ARDS patients with ventilator-induced diaphragmatic dysfunction and ICU-acquired weakness who are transitioning from controlled to partial ventilatory support probably present an abnormal respiratory pattern which exacerbates lung and muscle injury. Physiological-oriented ventilatory approaches based on prone positioning or semi recumbent positioning with abdominal binding at spontaneous breathing onset, could decrease lung and muscle injury by favoring a better neuromuscular efficiency, and preventing intense inspiratory efforts and high transpulmonary driving pressures, as well as high-magnitude pendelluft. In the current project, in addition to perform a multimodal description of the severity of ventilator-induced diaphragmatic dysfunction and ICU-acquired weakness in prolonged mechanically ventilated ARDS patients, prone positioning and supine plus abdominal binding at spontaneous breathing onset will be evaluated.

Rationale Acute respiratory distress syndrome (ARDS) is a frequent cause of hypoxemic respiratory failure with a mortality rate of approximately 30%. The identification of ARDS phenotypes, based on focal or non-focal lung morphology, can be helpful to better target mechanical ventilation strategies of individual patients. Lung ultrasound (LUS) is a non-invasive tool that can accurately distinguish 'focal' from 'non-focal' lung morphology. The investigators hypothesize that LUS-guided personalized mechanical ventilation in ARDS patients will lead to a reduction in 90-day mortality compared to conventional mechanical ventilation.

Rehabilitation of Critically Ill Patients With SARS-CoV-2 Variants in ICU With Limited Resources...

COVID-19 Acute Respiratory Distress Syndrome

Acute rehabilitation in critically ill patients can improve post-intensive care unit (post-ICU) physical function. Scientific evidence has considered neuromuscular electrical stimulation (NMES) as a promising approach for the early rehabilitation of patients during and/or after ICU. Neuromuscular electrostimulation can be an alternative form of muscle exercise that helps to gain strength in critically ill patients with COVID -19, due to the severe weakness that patients experience due to longer MV, analgesia and NMB duration. Thus, the general objective of evaluating the effects of an early rehabilitation protocol on the strength and functionality of patients affected by SARS-CoV-2 variants and specifically compare the effectiveness of NMES associated with the functional rehabilitation protocol(FR). Also, describe demographics, clinical status, ICU therapies, mortality estimates and Hospital outcomes, of every patients admitted in ICU during the observation periods.

The scientific community is in search for novel therapies that can help to face the ongoing epidemics of novel Coronavirus (SARS-Cov-2) originated in China in December 2019. At present, there are no proven interventions to prevent progression of the disease. Some preliminary data on SARS pneumonia suggest that inhaled Nitric Oxide (NO) could have beneficial effects on SARS-CoV-2 due to the genomic similarities between this two coronaviruses. In this study we will test whether inhaled NO therapy prevents progression in patients with mild to moderate COVID-19 disease.
