Active clinical trials for "Lung Injury"

Background: Ventilator induced lung injury (VILI) remains a problem in neonatology. High frequency oscillatory ventilation (HFOV) provides effective gas exchange with minimal pressure fluctuation around a continuous distending pressure and therefore small tidal volume. Animal studies showed that recruitment and maintenance of functional residual capacity (FRC) during HFOV ("open lung concept") could reduce lung injury. "Open lung HFOV" is achieved by delivering a moderate high mean airway pressure (MAP) using oxygenation as a guide of lung recruitment. Some neonatologists suggest combining HFOV with recurrent sigh-breaths (HFOV-sigh) delivered as modified conventional ventilator-breaths at a rate of 3/min. The clinical observation is that HFOV-sigh leads to more stable oxygenation, quicker weaning and shorter ventilation. This may be related to improved lung recruitment. This has however to our knowledge not been tested in a clinical trial using modern ventilators. Purpose, aims: To compare HFOV-sigh with HFOV-only and determine if there is a difference in oxygenation expressed as a/A-ratio and/or stability of oxygenation expressed as percentage time with oxygen saturation outside the reference range. To provide information on feasibility and treatment effect of HFOV-sigh to assist planning larger studies. We hypothesize that oxygenation is better during HFOV-sigh. Methods: Infants at 24-36 weeks corrected gestational age already on HFOV are eligible. Patients will be randomly assigned to HFOV-sigh (3 breaths/min) followed by HFOV-only or vice versa for 4 alternating 1-hours periods (2-treatment, double crossover design, each patient being its own control). During HFOV-sigh set-pressure will be reduced to keep MAP constant, otherwise HFOV will remain at pretrial settings. Outcome will be calculated from normal clinical parameters including pulx-oximetry and transcutaneous monitoring of oxygen and carbon-dioxide partial pressures.

The early initiation of Airway Pressure Release Ventilation in multi-system trauma patients decreases the incidence and severity of acute lung injury and Acute Respiratory Distress Syndrome and allows faster recovery of lung function.

Severe radiation-induced lung injury (RILI) occurs in approximately 20% of the lung cancer patients, who are treated with curative chemoradiation. In this study the investigators want to evaluate the prognostic value of baseline cardiac function assessed with echocardiography for prediction of RILI.

Phase I-II Clinical Trial - Safety and efficacy of umbilical-cord-derived mesenchymal stem cell (UC-MSC) in patients with Acute Lung Injury ,open label, controlled prospective study.

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.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are devastating disorders associated with lung inflammation, low oxygen levels and respiratory failure in children. Prevalence of ALI ranges from 2.2 to 12 per 100,000 children per year. Using these estimates, up to 9,000 children each year will develop ALI/ARDS, which may cause upto 2,000 deaths per year. Currently, there are no specific therapies directed against ARDS/ALI in children. In adult patients, use of steroids early in the course of ARDS appears promising. There are no published clinical trials examining the use of steroids for the treatment of ALI/ARDS in children. Hypothesis: Subjects with ALI/ARDS receiving steroids early in the course of disease (within 72 hours) and longer than 7 days will have improved clinical outcomes as compared to placebo control group as defined by (a) a decreased duration of mechanical ventilation and (b) significantly increased PaO2/FiO2 ratios.

with appropriate inspired oxygen concentrations, NPPV would prevent intubation and hence avert the poor outcome associated with the need of invasive ventilation in patients with ALI/ARDS.

A phase1/2, open label, dose escalation, safety and early efficacy study of CAStem for the treatment of severe COVID-19 associated with or without ARDS.

Randomized, placebo controlled study to determine if nebulized heparin may reduce the severity of lung injury caused by the novel coronavirus, also known as COVID-19

This study is aimed to determine whether low- and standard-pressure pneumoperitoneum have different impacts on troponin T（TnT) level as well as pulmonary complications after prolonged robot-assisted surgeries in the Trendelenburg position.
