Active clinical trials for "Acute Lung Injury"

The main hypothesis are: Passive and Active-Passive airway conditioning devices reduce the incidence of ventilator associated pneumonia Active-Passive airway conditioning devices reduce the incidence of endotracheal tube obstruction Nurses' workload is reduced with Passive and Active-Passive airway conditioning devices

The primary hypothesis was that early aspirin administration will decrease the rate of developing acute lung injury during the first 7 days after presentation to the hospital.

The purpose of this trial is to determine whether low tidal volume during intraoperative one-lung ventilation could decrease the incidence rate of postoperative acute lung injury compared to "normal" tidal volume.

More than 2 million patients worldwide receive heart surgery every year, majority of these surgical patients will undergo cardiopulmonary bypass. However, the incidence of postoperative acute lung injury due to cardiopulmonary bypass is still as high as 20% to 35%. According to clinical experience, the earlier lung damage is detected, the more successful the treatment will be. On the basis of traditional detection, the investigators found a new indicator, serum soluble vascular endothelial-cadherin, which are easy to obtain and have certain specificity. Importantly, they can predict postoperative acute lung injury within 1 hour after cardiac surgery. It is meaningful that this indicator can provide clinicians with early decision-making advice and immediate treatment for patients who may be at risk.

Hypothesis 1A: Oral Administration or Nasal Feeding of Huzhangxiefei Decoction will significantly attenuate sepsis-induced systemic organ failure as measured by overall response rate. Hypothesis 1B: Oral Administration or Nasal Feeding of Huzhangxiefei Decoction will attenuate sepsis-induced lung injury as assessed by the respiratory rate and oxygenation index. Hypothesis 1C: Oral Administration or Nasal Feeding of Huzhangxiefei Decoction will attenuate sepsis-induced lung injury as assessed by chest x-ray scale score, Chinese Medicine scale score. Hypothesis 1D: Oral Administration or Nasal Feeding of Huzhangxiefei Decoction will attenuate biomarkers of inflammation (C-Reactive Protein, Procalcitonin), vascular injury (Thrombomodulin, Angiopoietin-2), alveolar epithelial injury (Receptor for Advanced Glycation Products), while inducing the onset of a fibrinolytic state (Tissue Factor Pathway Inhibitor).

Surfactant replacement therapy (SRT) improves oxygenation and survival in NRDS and some infant ARDS. SRT was tried in adult ARDS with conflicting results. Research by Filoche and Grotberg helped to understand the failure of previous clinical trials and yielded a strong scientific rationale for SRT success, now allowing to design a new administration protocol for SRT in adults, to be tested by this clinical trial in COVID-19 adult ARDS patients. Patients will be randomized to receive either a bronchial fibroscopy alone (with aspiration of secretions) or a bronchial fibroscopy with administration of 3 mL/kg of a solution of poractant alpha diluted to 16 mg/mL and distributed into each of the 5 lobar bronchi.

The purpose of this study is to see if stress doses of hydrocortisone improve early outcome in patients who are in early stage of ARDS and with relative adrenal insufficiency.

30% of ARDS patients ventilated according to NIH protocol presents CT scan evidence of hyperinflation. Functional analysis of pressure-time curve (Stress Index=SI) has been shown to identify this condition in experimental settings. We tested the hypothesis that the SI is an accurate predictor of mechanical stress due to overdistention in ARDS patients.

A randomized, concurrent controlled trial to assess if adding sigh breaths to usual invasive mechanical ventilation of victims of trauma who are at risk of developing ARDS will decrease the number of days they require invasive mechanical ventilation.

This study is designed to compare three ultrasound-based aeration scores that were previously validated in specific populations, and to assess their correlation with computed tomographic measurement of pulmonary aeration in a population with different pathologies. Hypothesis: The "Loss of Aeration Score" will be more accurate than a simplified version and another widely used score, the "Lung Ultrasound Score".
