Acute respiratory distress syndrome (ARDS) accounts for almost 10% of intensive care units (ICU) admissions. Three ARDS stages have been defined, based on the PaO2/FIO2 ratio measured with positive end-expiratory pressure (PEEP) ≥5 cmH2O: mild (201-300 mmHg), moderate (200-101 mmHg), and severe (≤100mmHg). They represent 30.0%, 46.6%, and 23.4% of ARDS, respectively. Mechanical invasive ventilation (MV), the cornerstone of ARDS patient care, has a primary goal to protect the lung from ventilator-induced lung injury (VILI). Delivering MV in a prone position (PP) has been shown to improve oxygenation, protect the lung through a better homogenization of lung stress/strain, and stabilize hemodynamics. A meta-analysis of four randomized controlled trials showed beneficial effect of PP vs. supine position (SP) in the most hypoxemic patients. A fifth randomized controlled trial further showed a significant reduction in mortality with PP in ARDS patients with PaO2/FIO2 <150 mmHg, when neuromuscular blockade and long prone positioning sessions were used. Therefore, PP has since been strongly recommended for ARDS patients with PaO2/FIO2 <150 mmHg. Yet, there is limited evidence in patients with mild to moderate ARDS. There are, however, strong arguments supporting the need for a new trial in ARDS patients with PaO2/FIO2 in the range 150-300 mmHg: 1. There is no trial that has specifically tested PP in this ARDS subset; 2. PP is safe and has become a standard of care in ICU; 3. Should VILI prevention be a mechanism through which PP improves survival, this should be involved in all ARDS patients; 4. The mortality at hospital discharge in this subset of ARDS remains significant, amounting to 34.9% (95% confidence intervals 31.4-38.5%) in mild and 40.3% (37.4-43.3) in moderate stages; 5. Among 580 patients with mild ARDS at admission to the ICU, in-hospital mortality was 10%, 30%, and 37% for those who improved, persisted, and worsened ARDS, respectively. 6. Finally, PP has been shown to be cost-effective under commonly accepted thresholds. The hypothesis is that in patients within the 150-300mmHg PaO2/FIO2 range at the time of ARDS diagnosis, PP can reduce mortality as compared to a similar group left in the SP.
Prolonged prone position ventilation reduces the 30-day mortality in acute respiratory distress syndrome (ARDS) and in COVID-19 infection. A large number of patients with COVID-19 suffered from new-onset cardiac disease, therefore, ECG is crucial. However, there is limited data on the effects of prone position on the ECG in COVID-19 patients.
The implementation of this project will improve the effectiveness of surgical treatment and reduce the level of complications and mortality among patients with heart failure and heart failure in the terminal stage. The goal of the study. Improvement of organ-substituting technologies in the treatment of heart and respiratory failure. Objectives of the study. Objective 1. To study the restoration of organ function during implantation of extracorporeal membrane oxygenation (ECMO), as an organ replacement, in cardiac and / or respiratory failure. Objective 2. To study the results of applying organ-substituting technologies in the treatment of sepsis.
The main objective is to determine the short-term effect of prone positioning in infants with infection-associated severe acute respiratory distress syndrome. The investigators compare oxygenation parameters and measurements from electrical impedance tomography (EIT) and lung ultrasonography (LUS) in mechanically ventilated infants in prone position versus supine position after surfactant administration.
This study is a Randomized, Double-blinded, Placebo-controlled Phase Ib Study to Evaluate the Safety, Tolerability and Pharmacokinetics of STC314 Injection Administered as Continuous Intravenous Infusion in Chinese Patients with ARDS (Acute Respiratory Distress Syndrome).
The COVID-19, a pandemic as declare by WHO1, has a devastating impact on health and economic worldwide2. Literature suggests that acute respiratory distress syndrome (ARDS) develops over 20% of the infected individuals with Coivd-pneumonia3 along with other symptoms like fever followed by cough and dyspnea as well as chest pain in severe cases4. The current preventative strategies are non-specific10, and current interventions are predominantly supportive1. Recently, some studies have demonstrated anti-inflammatory actions for local anesthetics including lidocaine.
ARDS is characterized by a diffuse, bilateral, extensive alveolar-interstitial infiltrate related to damage to the alveolar membrane. Studies of lung morphology assessed by CT scan have shown 2 types of ARDS. When the loss of ventilation is posterior and caudal, and the pulmonary parenchyma is otherwise "healthy", ARDS is said to be focal. When the loss of ventilation is diffuse, associated with excess tissue affecting the entire lung parenchyma, ARDS is said to be non-focal or diffuse. Only one recent multicenter study has evaluated whether individualized PEEP adjustment according to lung morphology (focal vs. non-focal) could improve ARDS survival outcomes compared with standard of care. Results for the primary endpoint, 90-day mortality, were negative. But lung morphology was misclassified on CT occurred 85 (21%) of 400 patients. In addition, per-protocol analysis in which misclassified patients were excluded showed that mortality was significantly lower in the personalized ventilation group than in the control group. Lung ultrasound may be the ideal bedside imaging technique. The loss of pulmonary aeration and its variations induced by therapeutic maneuvers can be quantified by lung ultrasound. Lung ultrasound is a non-invasive, non-ionizing radiation method that can be easily used at the bedside. APRV ventilation coupled with spontaneous breathing activity prevents atelectasis formation, recruits less ventilated areas, prevents mechanical ventilation-induced lung injury and improves lung compliance. The hypothesis is that a "LUVS" ventilatory strategy composed of a bundle of measures all aiming at reopening the atelectatic pulmonary zones in focal ARDS (synergistic effect of spontaneous ventilation in APRV mode, early prone sessions, and adjustment of PEEP according to the patient's BMI), could decrease the number of days under mechanical ventilation, compared to protective ventilation with low tidal volume according to the current international recommendations
Multi-centered, randomized, open label clinical trial to study the safety and effectivity of hydroxychloroquine + azithromycin to treat COVID-19 symptoms in primary care patients.
The patients suffered from acute lung ininjury (200<PaO2/FiO2 ≤ 300) will be divided into two groups: MSCs-treated group: patients are treated by intravenous injection of hUC-MSCs suspention ; control group: patients were treated with vehicle(Albumin) . The standard Therapies of acute lung injury were the same in both groups. In the following-up days, all the patients were monitored by the same items to evaluate the therapeutic effects.
