Effect of Randomization to Neuromuscular Blockade on Physical Functional Impairment and Recovery...

Acute Respiratory Distress SyndromeNeuromyopathies

The proposed work will determine the effect of neuromuscular blockade on physical function and recovery in patients with ARDS. The investigators will conduct a prospective ancillary study at five PETAL clinical centers that will evaluate the neuromuscular structure and function of ROSE (Reevaluation of Systemic Early Neuromuscular Blockade) patients during and after critical illness, including in-person assessments at 6 months after hospital discharge. The investigators hypothesize that patients randomized to NMB will have an increase in ICU-acquired neuromuscular dysfunction during and after critical illness.

Surfactant for Neonatal Respiratory Distress Syndrome at High Altitude Areas:a Prospective Cohort...

Surfactant

The traditional concept believes that the etiology of neonatal respiratory distress syndrome (RDS) is immature development of lung,especially the surfactant synthesis system,and RDS is still one of the major causes of mortality and morbidity in newborns, especially premature infants.In recent years, using pulmonary surfactant replacement therapy (PS treatment) in the treatment of respiratory distress syndrome (RDS) is a major breakthrough in neonatal medicine.Combined with clinical practice and experience,and through Meta analysis of related randomized controlled trials (RCTs),it confirms that natural surfactant treatment can reduce mortality,the incidence of pulmonary air leaks (pneumothorax and interstitial lung emphysema),and the incidence of bronchopulmonary dysplasia (BPD) or 28-day-old mortality.For RDS in preterm infants whose gestation is <35 weeks ,surfactant replacement therapy is also more effective than in nearly term and full term infants.Therefore, in the analysis of cases of different gestational age groups,the investigators should focus on the study of premature infants cases.Due to less relevant research for using PS treatment to cure newborn RDS in high altitude area,this retrospective study conducts statistics and analysis of recently three-year cases in some hospital of high altitude area,to explore the treatment effect of the high altitude region and the impact of altitude on the treatment.

Assessment of Microcirculation Alteration With Both Sublingual Microcirculation and Near-infrared...

Acute Respiratory Distress Syndrome

Microcirculatory alterations are frequently observed in critically ill and severe sepsis patients characterized by a decrease in capillary density and an increase in heterogeneity of perfusion. This derangements result in microcirculatory shunting and oxygen extraction deficit, and plays a major role in the pathophysiology of sepsis and multi-organ failure. Loss of hemodynamic coherence between the macro- and microcirculation results in persistent and incomplete reversal of microcirculatory and regional hypoxia that is the major factor contributing to the development of organ failure. Current techniques permitting monitoring the microcirculation can be classified in two main groups: (1) Methods for evaluation of local tissue oxygenation as a surrogate of microcirculatory blood flow. (2)Methods allowing direct visualization of the microvascular network and microcirculatory blood flow. Near-infrared spectroscopy (NIRS) is a non-invasive technique for evaluating tissue oxygenation in vessels with a diameter < 1 mm (arterioles, capillaries, and venules). Recent systemic review studies have showed that patients with severe sepsis or septic shock have lower levels of StO2, moreover, survivors present higher levels of StO2 compared with non-survivors. Reactive hyperemia during vascular occlusion test (VOT) can be considered an integral test of microcirculatory reactivity, evaluating the tissue's ability to adjust oxygen extraction capabilities to oxygen delivery after a hypoxic stimulus induced by a transient interruption in blood flow. Continuous StO2 measurement and VOT derived StO2 deoxygenation slope and StO2 recovery slope have been found to be predictors of mortality and organ dysfunction. Sublingual microcirculation allows direct visualization of the sublingual microcirculation and for quantitative determination of variables of flow, capillary density, and flow distribution. Microvascular alterations including decreased functional capillary density, increased perfusion heterogeneity, and increased proportion of stopped and intermittently perfused capillaries, are more severe in non-survivors than in survivors. In addition, persistence of these alterations was strongly and independently correlated with multi-organ failure and mortality. ARDS is the most severe form of acute lung injury in ICU with mortality about 45% without achievement in ten years. However, only few studies were focused on the microcirculatory alterations in ARDS patients.

Inflammation and Distribution of Pulmonary Ventilation Before and After Tracheal Intubation in ARDS...

Acute Hypoxemic Respiratory FailureAcute Respiratory Distress Syndrome

Spontaneous breathing efforts in patients with respiratory failure connected to mechanical ventilation, has been associated with strong respiratory muscles activity. However, these mechanisms may will be present in patients with acute lung deseases who are breathing with no ventilatory support. We hypothesize that spontaneous breathing during acute respiratory failure could induced lung inflammation and worsen lung damage. Hereby, the connection to a ventilatory support tool, may protect the lungs from spontaneous ventilation-induced lung injury. To test our hypothesis, our aim is to determine the effects of spontaneous breathing in acute respiratory failure patients, on lung injury distribution; and to determine whether early controlled mechanical ventilation can avoid these deleterious effects by improving air distribution.

A Realworld Study of Acute Respiratory Distress Syndrome in China

Acute Respiratory Distress Syndrome

ARDS is a critical respiratory disease caused by endogenous and exogenous factors. The mortality of ARDS varies from 30 to 70%. In 2012, a new international diagnostic criterion has been put forward. Yet, its feasibility, reliability and validity need to be tested. Meanwhile, the correlation of different severity and prognosis remains unclear. As so far, the epidemiological information about ARDS in China is lacking. Investigators plan to conduct a multi-center observational study(real-life study) to investigate the risk factors, morbidity, management and prognosis of ARDS in China, in order to facilitate standardization of diagnosis and management of ARDS and provide basic data and idea for further clinical intervention studies.

Pathological Findings of Fatal COVID-19

SARS-CoV-2Covid193 more

The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a new coronavirus discovered in December 2019 in Wuhan, China and currently responsible of a worldwide outbreak and the death of more than 55,000 patients in France. The more severe form of COVID-19 disease induces a pneumonia with profound hypoxemia which may require invasive mechanical ventilation. It is estimated that 5% of COVID-19 patients are admitted to the Intensive Care Unit (ICU) for management. Hospital mortality in patients who develop severe acute respiratory distress syndrome (ARDS) ranges between 40% and 60%. The investigators purpose to investigate the pathological findings of COVID-19 patients who died from ARDS in the ICU by doing post-mortem lung biopsies

Cerebral Bleeding in COVID-19 ARDS Patients on Veno-venous ECMO

Acute Respiratory Distress SyndromeExtracorporeal Membrane Oxygenation Complication1 more

Critically ill patients with severe acute respiratory distress syndrome (ARDS) sometimes require treatment with veno-venous extracorporeal membrane oxygenation (ECMO) to support gas exchange. To prevent clotting of the ECMO circuit, these patients need to be anticoagulated. This protective anticoagulation also leeds to an increased bleeding risk. Most critically ill COVID-19 patients suffer from an ARDS and some require ECMO support. However, the optimal strategy and targets for the anticoagulation of these patients remain uncertain. Studies have shown that COVID-19 is associated with endotheliopathy probably leading to procoagulatory effects. On the other hand, the incidence of bleeding complications associated with this endotheliopathy is not clear and remains to be elucidated. Anticoagulation of COVID-19 patients on ECMO thus poses a challenge for clinicians. The hypothesis of the current project is that COVID-19 patients with ARDS on ECMO exhibit a higher number of bleeding complications compared to historical control patients with non-COVID-19 ARDS requiring ECMO support.

Combined Lung Ultrasounds and Transthoracic Electrical Bioimpedance in Preterm Infants With Respiratory...

Respiratory Distress Syndrome in Premature InfantPatent Ductus Arteriosus After Premature Birth1 more

Respiratory distress syndrome (RDS) is among the most common complications of preterm birth, and typically becomes manifested soon after birth. A failure of the rapid reuptake of fetal lung fluids after birth, with subsequent liquid retention in the alveolar space, together with the deficit of surfactant proteins ensuing from lung immaturity represent the leading mechanisms for the development of RDS, which may require different levels of respiratory support. An increasingly used method for the evaluation of the neonatal lung is pulmonary ultrasound, which allows assessing alveolar fluids and other pathological conditions in a non-invasive manner, and has been shown to predict the need for respiratory support and for surfactant administration in preterm infants with RDS. However, this method requires specific training, is operator-dependent and does not provide a trend able assessment over time. Transthoracic electrical bioimpedance (TEB) allows continuous and non-invasive monitoring of static and dynamic thoracic fluids. It has been recently introduced in neonatal clinical practice to assess such hemodynamic parameters as cardiac output and also quantifies static thoracic fluids contents (TFC). This method provides continuous and non-operator dependent data on the pulmonary fluid status over time and does not require specific training. The combination of lung ultrasound with TEB could open to new diagnostic and prognostic perspectives in preterm infants with RDS.

COVID-19 : Transcutaneous pO2 and pCO2 as Predictive Factors for Acute Respiratory Destress Syndrome...

COVIDAcute Respiratory Distress Syndrome1 more

The first case of a person infected with SARS-Cov-2 virus can be tracked back on November the 17th, 2019, in China. On March 11, 2020, the World Health Organization (WHO) declared COVID-19 outbreak a pandemic. On April 13, COVID-19 is affecting 210 countries and territories worldwide, about 2 million positive cases have been officially declared along with 115.000 deaths. The real number of infected and deaths is scarily higher, considering that up to 65% people are asymptomatic and thus, not tested. The percentage of patients with COVID-19 needed for intensive care unit (ICU) varied from 5 to 32% in Wuhan, China. It was up to 9% in Lombardy, Italy. According to available data from Lombardy, 99% of patients admitted to the ICU needed respiratory support (88% invasive ventilation, 11% non invasive ventilation). The aim of the present investigation is to test the hypothesis whether transcutaneous partial O2 and CO2 pressures may be reliable predictive factors for acute respiratory distress syndrome (ARDS) development in hospitalized clinically stable COVID-19 positive patients and to clarify the role of the Angiotensin Converting Enzyme 2 (ACE2) and its final product, angiotensin 2 (Ang II) in the pathogenesis of this systemic disease. We also aim to test the hypothesis that plasma concentration of Clara Cell protein (CC16) and surfactant protein D (SPD), which are a biomarkers of acute lung injury, are severely decreased in COVID-19 positive patients and the plasma concentration is related to the severity of lung injury.
